NeonMail installs straight from the web — no app store, no Google account needed. Add it to your home screen and it opens full-screen like any native app.
The one-tap install button appears in browsers that support it (Chrome/Edge on Android & desktop). On iPhone, use Safari's Share → Add to Home Screen. Instructions below.
Prefer a raw install file? Grab the signed APK above and open it (you may need to allow installs from your browser).
iOS installs web apps through Safari's Share menu — the same NeonMail, on your home screen.
