Get the ParaTrak app

First time installing? You'll need Apple's TestFlight app first (free, blue paper-plane icon) — it's the beta installer Apple requires. Install it, return here, tap Download for iPhone, then Accept and Install in TestFlight. If it asks for a redemption code, TestFlight isn't installed yet.

ParaTrak installs from a direct download, not the Play Store. Tap Download for Android to get the .apk. Chrome may warn that the file could harm your device — that appears for every sideloaded app; tap Download anyway. Open it, allow your browser to install apps if asked, then tap Install. The APK is built and signed by ParaDocs and updates over the air after that.
