Best App Marketing Agencies in 2025 (Updated List + Industry Insights)

There are more than 7 million apps floating around the iOS App Store and Google Play Store right now. Every single one is fighting for visibility, downloads, and, most importantly, loyal users.

The truth? Just building a great mobile application isn’t enough anymore. Without a clear marketing strategy, even the most innovative apps end up buried under competitors.

That’s where a mobile app marketing agency comes in. The right partner doesn’t just run ads; they help you design and execute data-driven strategies that push your app into the spotlight and keep it there.

From user acquisition to app store optimization (ASO), from tracking conversion rates to boosting long-term retention, the best agencies connect the dots so your app not only gets downloaded, but actually used.

But here’s the catch: picking an agency in 2025 isn’t simple. The market is saturated with digital marketing agencies that claim to do “everything,” yet few have the deep mobile expertise to deliver real app growth.

Add in rising ad costs, stricter privacy rules, and a growing emphasis on app visibility, and the stakes have never been higher.

So, which team deserves your trust—and your budget? That’s exactly what we’ll unpack here.

TL;DR: The Quick List of 2025’s Top Contenders

If you’re pressed for time, here’s the shortlist. But keep scrolling for the details, because the differences between these agencies could make or break your next big push.

• REPLUG – Best Full-Service Mobile App Marketing Agency
  Specializing in Paid UA, ASO, MMP setup, OEM ads, and analytics. Trusted by Bolt, Le Figaro, McDonald’s, BILD News, and many more.
• AppTweak – Best for App Store Optimization (ASO)
  If your focus is purely on organic traffic and app store rankings, their ASO tools and managed services are top-notch.
• Singular – Best for Attribution and Analytics
  A leading MMP that gives clarity on campaign performance. Pair it with an agency like REPLUG for full execution.
• BrightApps Media – Good for MVP-Stage Startups
  A small boutique agency handling early-stage marketing campaigns with limited budgets.
• NextGen App Growth – Best for Local EU Markets
  Regional campaigns with a personal touch, though not built for global scale.

What Is Mobile App Marketing (and Why It’s Getting Trickier)?

Mobile app marketing is the umbrella term for all the marketing efforts designed to make your app successful before, during, and after its launch.

Think of it as the backbone of your app’s growth strategy. It blends creativity and analytics to boost user acquisition, strengthen retention, and maximize conversion rates.

In 2025, app promotion isn’t just about pushing ads on Meta or TikTok. It’s about orchestrating a mix of:

• Paid Media: Smart PPC ad campaigns across Google Ads, Apple Search Ads, TikTok, and Meta.
• App Store Optimization (ASO): From metadata tweaks to high-performing screenshots that drive app installs.
• Influencer Marketing & Social Media Marketing: Especially for lifestyle, fitness, or dating apps, where authentic voices sway audiences more than banner ads ever could.
• Email Marketing & CRM: Building loyalty and engagement in app through personalized messaging and user flows.
• MMP Setup & Analytics: Without accurate attribution, your ROI is just guesswork. Tools like Singular, AppsFlyer, or Adjust ensure every click is accounted for.
• OEM Ads: For transactional apps, placements on devices from Xiaomi or Samsung can give you a “first impression” edge—95% of users download new apps within 48 hours of setting up a phone.

And while this might sound overwhelming, the goal is straightforward: increase app visibility, improve performance, and deliver measurable ROI.

The problem is, many mobile app marketing companies claim to do all this but lack the data-driven approach or in-house expertise to deliver.

That’s why finding the best app marketing agency isn’t just a line on your to-do list—it’s the difference between hitting your KPIs and watching your download curve flatline.

2025 App Marketing Trends You Can’t Ignore

If 2023 was about adapting to post-IDFA chaos and 2024 focused on short-form ad creative, then 2025 is shaping up to be the year of precision + personalization. And no, we’re not talking fluffy personalization like “Hi, .”

We mean serious segmentation, hyper-local targeting, and budget efficiency across every channel. Here’s what’s shaping the year for mobile app marketing professionals:

1. CPI Costs Are Not Playing Around

We’re seeing CPI (cost per install) increase across almost every vertical. Some as much as 21.4% year-over-year.

This means your marketing strategy needs to work harder, not just louder. Throwing more money into Meta or Google Ads without optimizing app store performance, messaging, or creative testing is like filling a leaky bucket.

Tip: Pair your paid media with solid ASO and in-app retention strategies to make every click count.

2. OEM Marketing Is Having a Moment

Remember when OEM ads were the weird cousin of UA strategies? Not anymore.

With more users downloading apps during device onboarding, placements through partners like Xiaomi, Transsion, and Samsung are becoming an essential user acquisition channel, especially for ecommerce, fintech, and utility apps.

• 95% of users download apps within 48 hours of device setup.
• The visibility and intent are unmatched—no algorithm gating you.

If you're not working with a mobile app marketing agency that understands OEM ads, you're likely missing out on growth opportunities.

3. Retention > Installs

The obsession with app installs is over. In 2025, app marketers are being judged by Day 7 and Day 30 retention, not flashy install spikes. That’s why agencies need to know their way around CRM systems, email marketing, push notifications, and yes, sometimes even onboarding design.

Retention loops aren’t sexy. But they’re what gets you to profitability.

4. Creative Velocity Is the New Ad Budget Multiplier

In a world where attention spans are shorter than ever (TikTok, we see you 👀), ad creative burns out fast. Teams that test weekly outperform those testing monthly by a mile. This trend is pushing agencies to adopt more agile workflows and creative automation.

If your agency hasn’t updated your video ad in 6 weeks? That’s not a partner. That’s a placeholder.

5. Localization Is the Hidden Growth Lever

Want to scale outside your home market? Localizing your app store assets, in-app messaging, and even your influencer partnerships can unlock massive upside.

Agencies that skip market research or use Google Translate to localize your ASO? Not the award-winning ones, apparently.

What to Look for in a Mobile App Marketing Agency (Without the Corporate BS)

Finding the best app marketing agency isn’t about scrolling through Clutch directories or seeing who posts the most on LinkedIn.

It’s about knowing what matters—and being able to tell the difference between an agency that “talks mobile” and one that lives and breathes it.

Let’s break it down.

1. Mobile-first, not “also does mobile”

There’s a big difference between a digital marketing agency that offers app services as a side hustle and a true mobile app marketing agency that specializes in it.

If their homepage talks more about websites, blogs, and email funnels than app installs, MMPs, or retention metrics, you’re probably not in the right place.

You need someone who understands:

• App store algorithms (ASO + metadata)
• Channel-specific UA strategies (TikTok, Apple Search Ads, Google Ads)
• In-app user behavior and engagement metrics
• Funnel leaks and conversion rate drops

2. Real performance marketing: not vanity metrics

If they’re selling you on impressions, likes, or “brand lift” without mentioning ROAS, CPA, CPI, or retention, it’s a red flag. A solid app agency should speak in numbers, and they should break those numbers down per cohort and channel.

Ask them:

• How do you define success?
• Can I see case studies or past campaign results?
• What tools do you use for measurement and attribution?

(Spoiler: if they don’t mention Singular, Adjust, or AppsFlyer… yikes.)

3. Attribution and MMP setup = must-have

No MMP, no clarity. That’s just how it works in 2025. You can’t measure conversion rates, user retention, or return on investment without proper attribution tools.

The best agencies will either help you set up your MMP or optimize an existing setup, ensuring you’re tracking across platforms, devices, and events.

Bonus if they offer audits to find attribution leaks (REPLUG does that, by the way 😉).

4. Transparency in pricing and ad ownership

Let’s be blunt—some agencies will trap you in long-term retainers, hide spend behind vague dashboards, or worse: own your ad account. If you can’t access your campaign data directly, you're being held hostage.

The best agencies will:

• Give you access to every account
• Let you pause, scale, or test freely
• Tell you exactly where your budget is going

That’s how it should be.

5. A track record of real case studies

Not just “we helped a global dating app increase installs.” You want receipts. Real client names (when possible), screenshots, before-and-after performance metrics, and a clear explanation of how they got results.

If all you see is fluff and fancy words like “innovative solutions for scalable outcomes,” hit that back button fast.

6. A team you actually want to work with

This one’s often overlooked. You’ll be in the trenches with your agency: running experiments, testing creatives, pushing deadlines. If you don’t vibe with their team or if they act like they're doing you a favor by responding to emails, run.

Look for:

• A partner, not a vendor
• A team that teaches, not gatekeeps
• People who’ve been through your growth stage before

Comparison of the Best App Marketing Agencies in 2025

Let’s be honest: not every agency that calls itself a mobile app marketing agency deserves to be on this list. Many are just digital marketing companies that added “app” to their pitch deck.

But a handful stand out—some for specific strengths, some because they’ve proven they can actually move the needle for apps.

Here’s how they stack up.

1. REPLUG — The Best App Marketing Agency in 2025

If you want a partner that treats your app growth like its own KPI, this is where you stop scrolling.

• Headquarters: Berlin, Germany
• Core Services: Paid UA, ASO, OEM marketing, MMP setup, analytics, app launch
• Clients: Bolt, Le Figaro, BILD News, McDonald’s, upday for Samsung, Ecosia. Just to name a few.
• Why They’re #1:
  • Proven case studies: For one client, REPLUG boosted app visibility by 512% in the US and keyword rankings in Germany by over 245%. No BS, all case studies are live on REPLUG’s website.
  • Unique strength in OEM ads: Thanks to partnerships with Xiaomi, Oppo, Vivo, and BranchAds, REPLUG delivers clean, fraud-resistant traffic.
  • Data-driven strategies: Every campaign is tied to KPIs—whether it’s retention, conversion rates, or ROAS.
  • Full transparency: Clients own ad accounts, see every euro spent, and get access to custom analytics dashboards.
    
    
• Awards: Clutch Global Leader 2024, Finalist at the App Growth Awards 2024, Winner at the 2025 Web Excellence Awards
• Drawback: These marketing experts only work with apps that are ready to scale. If you’re still in MVP mode, REPLUG isn’t the right fit for digital marketing services.

2. AppTweak — Best for ASO and Organic Growth

AppTweak isn’t an agency in the traditional sense—it’s an ASO tool. Their managed services team helps apps nail their app store optimization strategies with a laser focus on keyword rankings and creative performance.

• Specialty: ASO, metadata optimization, screenshots, localization
• Strengths: Strong tools for SEO-style keyword research in the app stores; helpful for new app launches.
• Limitation: Doesn’t cover user acquisition, OEM, or influencer marketing. Works best as a complement to a full-service agency.

3. Singular — The Analytics Backbone

Singular is an MMP, not an agency, but it’s impossible to ignore if you’re serious about accurate attribution. Agencies without Singular (or similar tools) are essentially guessing where your installs came from.

• Specialty: Attribution, analytics, ROI measurement
• Strengths: Detailed cohort analysis, fraud detection, data-driven insights
• Limitation: Needs to be paired with an actual agency to run campaigns

4. BrightApps Media — Boutique for Bootstrapped Startups

A small mobile app marketing agency with limited reach, BrightApps Media focuses on startups with tight budgets testing their MVP.

• Specialty: Paid media campaigns on social platforms, AI solutions
• Strengths: Friendly support, flexible pricing
• Limitation: Limited scale; weak on ASO, MMP, or OEM

5. NextGen App Growth — Regional Focus, EU Markets

NextGen Apps is a niche player for early-stage companies targeting specific European markets. They pride themselves on personalization but can’t compete globally.

• Specialty: Local marketing campaigns, app development
• Strengths: Good for localization and grassroots visibility
• Limitation: No advanced performance marketing or OEM support

The Stages of App Marketing: Awareness → Acquisition → Retention

Think of app marketing like running a marathon. You can’t just sprint the first mile (hello, user acquisition) and expect to win the race.

Real app growth requires pacing, planning, and knowing when to push harder. In 2025, agencies that focus only on installs without thinking about retention or user engagement are doing half the job.

Here’s how the stages break down:

Stage 1: Awareness

This is where you plant the seed. If people don’t know your app exists, they won’t search for it—simple as that. Awareness campaigns often include:

• Social Media Marketing: Instagram, TikTok, and Facebook ads that create noise.
• Influencer Marketing: UGC-driven TikTok videos or Instagram Stories that show real people using your app.
• Market Research: Understanding your target audience before you even launch. Who are they? Where do they spend time? What messaging works?
• Creative Content: Engaging video ads, memes, and even interactive polls—because bland content dies fast in feeds.

Done right, awareness campaigns give you a pool of high-intent prospects before your first install even happens.

Stage 2: Acquisition

Now it’s time to convert awareness into downloads. This is where paid media and app store optimization (ASO) team up:

• PPC Campaigns: Running on Google Ads, Apple Search Ads, and TikTok.
• ASO: From keyword-rich metadata to persuasive screenshots that boost conversion rates.
• Localization: Customizing your Google Play Store and iOS App Store pages for each market.
• In-App Incentives: Offering bonuses, discounts, or free trials to drive those first app installs.
• OEM Ads: Showing your app on new devices during onboarding—an overlooked app marketing strategy with incredibly high CTRs.

The goal? Quality installs, not just vanity download spikes, for your app performance.

Stage 3: Retention

This is where most apps stumble. Acquiring users is expensive—losing them after Day 1 is brutal. That’s why top agencies put serious energy into retention strategies:

• CRM Systems: Tracking user journeys and tailoring outreach.
• Email Marketing & Push Notifications: Personalized reminders, special offers, and “we miss you” nudges.
• In-App Experiences: Onboarding flows that don’t bore or confuse, personalized recommendations, and gamification elements.
• Performance Marketing for Retention: Testing new creatives and re-engagement ads for churned users.
• Automation: Using tools to trigger messages at the perfect time—whether it’s a renewal reminder or a reward unlock.

Retention is about increasing lifetime value (LTV) and ensuring your marketing efforts pay off in the long term.

👉 So, awareness brings them in. Acquisition gets them to install. Retention keeps them coming back. Skip any stage, and your mobile app marketing strategies will collapse like a poorly built Jenga tower.

Metrics That Actually Matter (Because Vanity Numbers Don’t Pay the Bills)

It’s easy to get wowed by flashy charts showing “millions of impressions” or “X% engagement.”

But here’s the truth: if those numbers don’t tie back to installs, retention, or revenue, they’re basically just noise. A good mobile app marketing agency doesn’t drown you in vanity metrics—they show you the KPIs that directly link to your bottom line.

Here are the metrics you should demand to see in every report:

1. App Visibility

Your app’s presence in the iOS App Store and Google Play Store matters more than ever. This means tracking:

• Keyword Rankings: How your app shows up for high-intent search terms.
• Featured Placements: Whether you’re winning premium real estate in the app stores.
• Conversion Rates from Store Pages: Are your screenshots and messaging convincing users to hit “Download”?

If your agency can’t explain your app’s visibility growth, you’ll struggle to scale organic traffic.

2. Conversion Rates (CVR)

This isn’t just about installs—it’s about the efficiency of your funnel.

• Ad Click → Store Visit → Install: Every step matters.
• Track CVR for each PPC campaign, creative, and keyword.
• Identify leaks: Is it the ad, the store listing, or the onboarding?

A drop in CVR without answers? That’s a red flag for your agency.

3. Retention Rates

Downloads mean nothing if users churn after Day 1. Retention is where you see real user engagement:

• Day 1 Retention: Did they even open the app?
• Day 7 Retention: Are they sticking around past the novelty stage?
• Day 30 Retention: Is your app becoming part of their routine?

Retention connects directly to monetization, especially for ecommerce, subscription, and gaming apps.

4. Return on Ad Spend (ROAS)

This is where you separate the serious agencies from the pretenders. A true performance marketing partner will break down ROAS:

• By channel (Meta, TikTok, OEM, Google Ads)
• By audience (geography, demographic, interest)
• By creative (video vs static, influencer vs branded)

If you don’t know where your best installs come from, you’re wasting money.

5. Cohort Analysis & LTV

It’s not just about installs—it’s about value over time.

• Cohort Analysis: See how users acquired in January behave compared to those from March.
• Lifetime Value (LTV): How much revenue each user generates.
• Combined with retention, this tells you which app marketing strategies actually work.

👉 The bottom line: Don’t settle for a digital marketing agency that hands you surface-level reports.

The best app marketing agency and marketing team will deliver numbers that explain why you’re growing (or why you’re not) and give you a roadmap to fix it.

Pricing: How Much Does App Marketing Cost in 2025?

Let’s not sugarcoat it: marketing an app in 2025 isn’t cheap. Between rising CPI costs, the need for a proper MMP setup, and the reality that creative fatigue kicks in faster than ever, you’ll need a budget that matches your ambition.

But here’s the good news: done right, every euro you invest comes back to you with measurable growth.

So, what does it actually cost to work with a mobile app marketing agency?

Startup Stage (MVP or Early Launch)

• Budget Range: €3K–€7K/month
• What You Get: Basic app store optimization (ASO), light PPC campaigns on Meta or TikTok, and some email marketing or CRM flows.
• Goal: Get initial app installs, test messaging, and validate market fit.
• Best Fit: Bootstrapped startups and teams testing the waters before scaling.

Growth Stage (Scaling with Confidence)

• Budget Range: €15K–€30K/month
• What You Get: Full-stack performance marketing including Google Ads, Apple Search Ads, paid social, advanced ASO, creative testing, and MMP attribution.
• Goal: Increase user acquisition while improving conversion rates and retention.
• Best Fit: Apps with some traction that need a steady stream of new users and clean data to prove ROI.

Scale Mode (Global Expansion)

• Budget Range: €40K+/month
• What You Get: Multi-channel paid media, OEM ads, influencer marketing, global localization support, and automated CRM campaigns for retention.
• Goal: Dominate app store categories, expand into new regions, and maximize lifetime value (LTV) with a strong return on investment.
• Best Fit: Established apps ready to break into new markets or verticals.

Tip: If an advertising agency promises “scale” on less than €5K a month, it’s either skipping proper attribution or giving you traffic that won’t convert.

The best app marketing agencies are upfront about pricing because they know transparency builds trust and results.

FAQs - You Asked, We Answered

1. What does an app marketing agency actually do?

A good one helps your app grow. That includes everything from user acquisition (UA) and app store optimization (ASO) to MMP setup, creative testing, CRM strategies, and even OEM placements. It’s not just about installs—it’s about retention, ROI, and sustainable growth.

2. How much does it cost to market an app in 2025?

Budgets typically start around €3–5K/month for early-stage apps and scale up to €30–50K/month for more aggressive marketing campaigns. It depends on your goals, channels, and whether you're targeting local markets or global reach.

3. Is ASO still worth it in 2025?

Absolutely. With CPI rising and app store competition getting tougher, ASO is essential for boosting organic traffic, increasing conversion rates, and lowering your paid UA costs.

4. What’s the role of an MMP in app marketing?

An MMP (Mobile Measurement Partner) like Singular, Adjust, or AppsFlyer helps you track installs, user behavior, and revenue across channels. It’s the only way to get accurate attribution and make smart data-driven decisions.

5. Do I really need influencer marketing?

It depends on your audience. For consumer-facing apps in categories like lifestyle, fitness, or beauty, influencer and UGC-style creative can outperform traditional ads, especially on platforms like TikTok.

6. Is OEM marketing just hype?

Not at all. With most users downloading apps in the first 48 hours of getting a new phone, OEM ads offer high-intent placements that no algorithm can block. They’re especially effective for transactional apps like delivery, shopping, mobility, and travel.

7. Can REPLUG help with app launch strategy?

Yes. We’ve worked with apps from pre-launch to global scale. From localization to creative strategy to app store readiness, we’ve got you covered.
