One home-screen icon.
All four trainers, interactive diagrams, quizzes, reading lessons and bundled research in one place.
You’re using the standalone app.
Add TRQC to your screen
iPhone / iPad: open this site in Safari, tap Share, then Add to Home Screen. Leave “Open as Web App” enabled if shown, then tap Add.
Android / computer: use Install below when available, or your browser’s Install app / Add to Home screen menu.
Then open the TRQC icon to use the app in its own window.
Offline access & updates
Preparing offline access…
The first download includes the lessons, activities and bundled research files. Wait for “Ready offline” before disconnecting. External websites and videos still require internet.
Updates preserve saved progress. Applying an update reloads open app windows; finish any unsubmitted exam first. Your device may remove offline files if storage runs low—reconnect to download them again.
Keep your progress
Progress is saved on this device. The home-screen app may have separate storage from Safari. To transfer it, export a backup in Safari, then open this page from the app and restore that file.
Close other trainer windows before restoring. Included course records replace their existing progress; export first if you want to keep a copy.
