Installing the mobile app
Add EverySqueeze to your phone's home screen after signing in there with the QR code or your personal sign-in link.
The mobile app isn't in the App Store yet: it's a web app you add to your phone's home screen. Sign in on your phone first, by scanning the QR code from your computer (Get it on your phone) or with a personal sign-in link (Phone access). After a QR sign-in your phone opens the app page and points at the button to tap.
iPhone
Open the link in Safari, then tap Share → "Add to Home Screen". It installs like a regular app icon; open it from there each time.
Android
Open the link in Chrome, then the menu (⋮) → "Add to Home screen".
Why it has to be installed this way
Each sign-in link and QR code works once, on the device that opens it — that's what ties the app to your phone without a password. Installing it to your home screen (rather than just bookmarking the page) is also what lets push notifications work, since a plain browser tab can't receive them the same way.
Asked to sign in again?
That sign-in is tied to your phone's browser session: if it's cleared (a browser reset, a new phone), scan a new code from Get it on your phone (or make a fresh link from Phone access) and re-add it to your home screen. A phone signed in with a code stays signed in while you use it (see Staying signed in). The Home Screen app keeps its own sign-in, separate from Safari: if it asks you to sign in, use "Email me a sign-in code" or "Paste sign-in link" there.
