TIIMO
Unlocking full iOS visibility and +36% revenue with the right iOS tracking stack.
CHALLENGE
Tiimo is a visual daily planning app designed to support neurodivergent individuals - including those with ADHD and autism - in managing routines, focus, and time. With a global audience and a subscription-driven business model, the app is available on both iOS and Android.
When Tiimo set out to sharpen the performance of its iOS growth engine, the team already had a solid acquisition foundation. They brought REPLUG in as a trusted partner to elevate tracking, attribution, and data clarity, areas that hadn’t been prioritized recently amid other roadmaps. The brief was clear: refine SKAN 4.0 configuration, enable seamless web-to-app attribution on Meta, and unify the AppsFlyer setup across channels.
Together, Tiimo and REPLUG co-piloted a focused technical upgrade that empowered the team to scale with confidence.
SKAN 4.0
NOT YET ACTIVATED
WEB-TO-APP META ATTRIBUTION NOT YET ENABLED
EVENT MAPPING & WINDOWS NOT YET STANDARDIZED
SOLUTIONS
SKAN 4.0
CONFIGURATION
We activated SKAN 4.0 inside Appsflyer’s Conversion Studio, mapping fine and coarse values to in-app events by user engagement levels. Postbacks were structured across all 3 activity windows, and lock windows were optimized - co-designed with Tiimo’s team - to support a subscription-driven model.
WEB-TO-APP META
TRACKING
Using Meta’s partner integration with Appsflyer, we enabled full web-to-app attribution—bypassing iOS privacy thresholds while improving campaign measurement. This allowed us to run Meta web-based iOS acquisition strategies with in-app event optimization enabled.
ATTRIBUTION HYGIENE ACROSS CHANNELS
We aligned all attribution windows to best practices (7d click / 1d view), standardized event naming, extended reattribution windows to 90 days, clarified the revenue events tracking, and configured missing SKAdNetwork schemas. All major channels and events were activated and validated in collaboration with Tiimo, aligning teams on a single source of truth.
CLIENTS SPEAK
-
Working with REPLUG honestly feels like working with extra team members who actually care about what we’re trying to achieve. They’ve been reliable and responsive from day one, always ready to provide feedback or answer any question, no matter how big or small. Their proactive approach, clear communication, and hands-on support gave us the confidence to scale our campaigns sustainably, and the improvements we’ve seen have been immediate.

IMPACTFUL CHANGES
2x INCREASE IN WEEKLY PAID SUBSCRIPTIONS
By unlocking full iOS attribution and bringing confidence to performance data, the team could finally increase spend where it mattered. With SKAN 4.0 configured and Appsflyer dashboards aligned, Tiimo was able to test and scale campaigns with clarity—resulting in a doubling of weekly paid subscriptions in just a few weeks.
UP TO 360% REDUCTION IN CPA ON META
Before the upgrade, CPAs on Meta were higher and fluctuated versus recent benchmarks. After enabling web-to-app tracking and optimizing event setup, the cost per trial start in the US dropped significantly, making Meta a reliable, scalable acquisition channel again.
CROSS-PLATFORM ATTRIBUTION RESTORED
As with many privacy-first iOS stacks, visibility had been limited: SKAN 4.0 wasn’t yet rolled out, and Meta web-to-app attribution wasn’t enabled. Within weeks, our joint setup delivered end-to-end visibility across Meta, SKAN 4.0, and AppsFlyer, giving Tiimo a durable foundation to optimize creative and spend.
