Open Source Tool Predicts App Conversion Churn

mrr7337 · hn · 2026-07-14

Rejourney is an open-source tool designed to predict experience leaks in web and mobile apps before they impact conversions.

By installing an SDK, it records user sessions, key conversion events, and interaction sequences. It then combines this with context like errors, API latency, and crashes, using heuristic clustering and an LLM to identify anomalous paths that cause user churn. The author created this project after losing many users due to confusing onboarding and UX in a campus app.
