- Auto-upload: recordings now upload automatically over Wi-Fi after each session — no manual step needed. - Vietnamese voice guidance: hand-presence and recording prompts are spoken in Vietnamese when the app language is set to Vietnamese. - More reliable uploads in China: fixed a network error that could appear right after signing in with a +86 phone number. - Fixed stuck video uploads: resumed uploads now treat the server as the single source of truth, resolving cases where a video could retry forever. - Safer recordings: metadata is now written the moment recording starts, so your data survives an unexpected app close. - Camera fix: turning the guide border off no longer causes a black camera screen. - Recording cards now show the capture time (HH:MM). - Various stability and UI improvements.

New: Referral system • Sign in with a real account — everyone now gets a personal referral code. • On first launch you can set a nickname and bind your upline's referral code, so work can be tallied by team / project. • Settings let you edit your nickname, view your own code, and bind and view your upline's code. Tap any field — code, UID, phone or email — to copy it. More reliable uploads • Videos now upload in chunks (multipart), so large files are far more robust and can resume after an interruption. • Interrupted uploads resume automatically when you reopen the app. • Upload failures now show the exact reason in both the list and detail views. • Fixed a case where a recording could be marked "uploaded" before all of its files had actually finished uploading. Camera & compatibility • Fixed the ultra-wide lens not being selectable on some Android devices. • More accurate lens detection for better capture metadata. • Camera initialization errors are now shown on screen. Plus various stability and layout refinements.

This update significantly improves recording and upload reliability: • Recording salvage: footage already captured is saved when a recording is interrupted by an incoming call, backgrounding, or an unexpected stop — no longer lost • Recovery on launch: the app scans for and restores unfinished recordings when reopened • Damage detection: damaged recordings are clearly distinguished from ones that can simply be re-uploaded • Discard confirmation: you're now asked to confirm before discarding an in-progress recording • More reliable uploads: automatic retry on transient network failures, plus fixes to the bulk-upload count and button state • Mainland China phone sign-in: faster, more reliable SMS verification codes • First launch now follows your device's system language

• Sign in with a phone-number verification code • Login flow and stability improvements
