Android app

Holy Grace for Android is the web app wrapped as a real app: full screen, on your home screen, with notifications. Installed from here, not from a store.

Install

1. Open the downloaded file. Android asks to allow installs from your browser — allow it once.
2. Tap Install. The app appears on your home screen as Holy Grace.
3. Open it. It runs full screen; your highlights, plans and offline packs are shared with the website in Chrome.
