Keep your plates close.

Install PlateHerder for a home-screen shortcut and its own app window.

iPhone and iPad

Open PlateHerder in Safari. Open the Share menu, choose Add to Home Screen, then Add.

Android and desktop

Use your browser's Install app or Add to Home screen option. Supported browsers may also offer an install button in the address bar.

You still need an internet connection for your private library, video playback, and extraction. Installing does not make your plates public.
