Two minutes, no app store
Morphora installs right from your browser — no App Store or Play Store needed. Once it's added, it opens full-screen like any other app, works offline, and sits right on your home screen.
Has to be done in Safari specifically — Chrome and other browsers on iPhone can't do this part, even though they can browse the site fine.
Works in Chrome, which is the default browser on most Android phones.
Once it's added, look for the Morphora icon right on your home screen — tapping it opens the app directly, without Safari or Chrome's address bar or tabs around it.
