Custom App-Install Banner
Put an “Install our app” button anywhere on your website — one click opens the install dialog on Android, and step-by-step instructions on iPhone.
Turn on the Branded Web App
The install banner needs an active Branded Web App: a verified custom domain, an uploaded logo, and the toggle switched on. Open Settings → Branded Web App and check that all three requirements are met — without them there is nothing to install.

Add a button that installs the app
In Website → Pages, open the page where you want the banner and add a Buttons strip (or edit one you already have). Give the button a label like “Install our app” and set its link to exactly #install-app. That special link is recognized by the platform — no code needed. Save and publish.
What happens when guests click
On Android and desktop Chrome/Edge the click opens the browser's native install dialog directly — one tap and the app is on the home screen. On iPhone and iPad a popup shows three short steps (Share → Add to Home Screen → Add), because Apple allows no direct install. In browsers that cannot install apps, guests are pointed to Google Chrome.
The button always works — even for guests who closed the automatic install banner earlier.
Building a fully custom banner? (advanced)
Strips not enough — you want your own design? Website → SEO → Custom scripts (body) accepts JavaScript that runs on every page of your site. Have the script build your banner element and either give the button a data-ot-install attribute or call otInstallApp() in its click handler — both trigger the exact same install flow as the strip button. This field takes JavaScript only, not raw HTML.
Test it on a real phone
Open your website on an Android phone in Chrome, tap the new button and confirm the install dialog appears. Then try an iPhone and walk through the three steps. Once installed, your logo sits on the guest's home screen and the app opens full-screen.
