Session Replay

SessionGlossaryApp SessionA single period of continuous user activity in an app, from open to close (or background past an inactivity timeout) — the atomic unit on which most engagement metri... replay is a tool that records anonymized user sessions in your mobile app — capturing screen interactions, taps, gestures, navigation paths, and (with permission) screen content. The recordings let product, design, and engineering teams watch real users navigate the app, surfacing UX issues, debugging crashes-in-context, and understanding behavior patterns that aggregate analytics can't show.

What session replay shows

• Screen navigation — which screens users visit, in what order, how long they stay.
• Taps and gestures — every interaction, including rage-taps (repeated taps on unresponsive elements).
• Form / input interaction — how users fill out forms, where they hesitate or abandon.
• Scroll behavior — how deep users scroll on screens, what they pause to read.
• Crash context — what happened in the 30 seconds before a crash.
• Funnel drop-offs — exactly what happened at each step where users abandon.

Some tools also include console logs, network requests, and performance metrics alongside the visual replay.

Privacy considerations — critical:

• Mask PII automatically — modern tools auto-detect and mask credit card fields, email inputs, password fields, personally-identifiable text. Verify your platform handles this correctly for your specific input types.
• GDPRGlossaryGDPR (General Data Protection Regulation)The EU's General Data Protection Regulation — the foundational privacy law governing how mobile apps collect, process, and share personal data of European users. / CCPA compliance — session replay captures user behavior; arguably "personal data" under GDPR.

• Block sensitive screens — payment screens, health information, identity verification flows should be excluded from recording entirely (not just masked).
• Document in privacy policy — disclose session replay use to users.
• Limit retentionGlossaryRetention (D1 / D7 / D30)The percentage of users from a cohort who return to the app N days after install. D1 = day-1 retention, D7 = 7-day, D30 = 30-day. The single most important non-reven... — recordings shouldn't be stored forever. 30-90 days is typical.

4. 04Investigate negative reviews — search for sessions matching specific behaviors mentioned in reviews.
5. 05Discover unexpected user behavior — find patterns analytics didn't tell you about (users using features in unexpected ways, finding hidden flows, getting stuck on UI elements).
