Keep the study
The house can sit on a phone, a tablet, and a Windows desk like any other app. It does not wait on a store. Chrome, Safari, and Edge already know how to keep it.
Phone and tablet
Chrome can install the study as its own app. Full screen. Home-screen icon. No browser chrome.
Open This Generation in Chrome.
Tap Install when Chrome offers it, or open the Chrome menu and choose Install app.
Confirm. The temple mark is now on the home screen.
Samsung Internet and Edge on Android can install it the same way. Firefox usually cannot.
What this is not
Play Store, the App Store, and the Microsoft Store each require their own review, certificates, and a published address. This Generation installs from the browser instead: a home-screen app on Android and iPhone, a windowed app on Windows. Same study. Same desk. Uninstall it the way you uninstall any other app.
Do the install in Chrome, Safari, or Edge on the device itself. A nested window cannot pin an icon to a home screen.
