Built by an indie developer who needed it.
AppMetricsKit exists because measuring a subscription app should not require choosing between your users' privacy, a data engineering team, or flying blind.
The story
AppMetricsKit is built by Marwan Akhandaf, an independent developer shipping iOS and Android apps. It started as the tool he wanted for his own apps: analytics that could answer the questions a subscription app actually runs on. Does onboarding reach the paywall? Do trials convert? Do renewals hold? It answers those questions without advertising identifiers or a customer managed analytics warehouse.
Existing products often separate product behavior from subscription revenue, or rely on broader identity models and complex query workflows. AppMetricsKit brings pseudonymous product events and subscription reporting together in a product sized for independent developers and small mobile teams.
It is an independent product, funded by its customers rather than by advertising or data resale. That business model aligns the product with the developers who pay for it.
Open where it counts
Privacy starts with architecture
AppMetricsKit does not require advertising identifiers or cross-app tracking. Configured account identifiers are hashed on device, and ingest guardrails remove detected risky payload keys before event storage. This reduces the personal data your analytics setup needs to process.
Subscription revenue is part of analytics
Usage charts alone cannot explain why trials convert or renewals change. AppMetricsKit provides a canonical subscription event taxonomy, paywall funnels, and authenticated webhook ingestion for RevenueCat, Adapty, and Superwall.
Built for independent developers
Volume-based pricing, a free tier, native SDKs, and focused dashboards keep the product practical for developers whose apps are their livelihood.
Built in the open where it matters
The Swift and Kotlin SDKs are open source on GitHub. The roadmap and changelog are public, and compliance guides cite primary sources so customers can inspect important product claims.
