Overview
Pick Plug is a mobile sports picks application where subscribers receive daily handicapper selections. The platform includes in-app purchases, backend subscription management, and push notification delivery.
Challenge
The client had a broken Android IAP flow and a backend that failed to correctly unsubscribe users — causing billing issues and poor user retention. The fix required expertise in both Android and server-side subscription logic.
Solution & Outcome
Audited and rewrote the Android IAP validation flow end-to-end, fixed the backend unsubscribe webhook handler, and implemented reliable push notification delivery for daily picks. IAP conversion errors dropped to zero. Unsubscribe failures were eliminated. The client reported significantly improved user retention and store reviews after the release.
