EVA installs on a phone as an app: its own window without the browser bar, an icon on the screen, alerts as notifications. It is the same terminal and the same account, not a separate app from a store.
“More” → “App and notifications” → the “Install” block → “Install the app”. The browser opens its own install window — confirm, and the EVA icon appears on the screen.
If instead of the button it says the browser does not offer install right now, EVA is most likely installed already: open it from its icon. Otherwise — browser menu ⋮ → “Install app”. If it says install is not available in this browser, open EVA in Chrome.
On iPhone and iPad only Safari installs. “More” → “App and notifications” → “Install the app” shows three steps. If this is not Safari, the top says “Open this address in Safari: only Safari installs on iPhone”.
Apple allows notifications only for sites added to the Home Screen: turn them on in the installed EVA.
In Chrome and Edge: “Settings” → at the bottom of the left column “Install the app”. When opened as an app, it says “Installed as an app” there.
“More” → “App and notifications” → “Notifications on this device” → “Turn on”. On a computer the same sheet is ⚙ Settings → at the bottom of the left column “App and notifications”. When notifications are on, it says “✓ On…” and has the “Test”, “Show example” and “Turn off” buttons. Tick “phone” on an alert (in the alert form — “To phone”) — the notification arrives even with EVA closed.
Subscription, alerts, favourites and the course are the same as in the browser. In the browser and in the installed EVA there are no banners offering to install it — only the button in settings. In the Telegram mini app, rarely — at most once a week — a line “Full version — the EVA app…” with an “Open” button appears at the bottom; × hides it, and it goes away by itself after 15 seconds.
