Use it in your browser
Nothing to install. This is the full app, not a preview of it, and it is the fastest way to try Momentum: you can be typing about four seconds from now.
Open the web appChrome, Safari, Firefox and Edge. Works on a phone too.
Install Momentum
Everything on this page is also on the home page — this one exists so you can send someone straight to it.
Install it on Android
.apkA proper app on your home screen, with the capture widget — one tap from the launcher to a captured thought.
Download for Android- Tap the download button. It is an .apk file, straight from the build server.
- Android will warn you about installing outside the Play Store — Momentum is not on it yet. Allow it for your browser.
- Open the file, install, done.
Updates arrive over the air after that. You will not reinstall for every change.
On an iPhone? There is no App Store build yet — that needs a paid Apple developer account, which comes later. Open the web app in Safari and add it to your home screen; it behaves like an app from there.
Your first two minutes
- Pick your language and tap through the three intro screens.
- Tap “Catch my first thought”. No sign-up, no email, no password.
- Type something real: “remind me to call the dentist tomorrow”.
- You get a receipt — a card showing exactly what was filed, built from what actually hit the database rather than from what the AI claims.
- Ask it “what’s on today?”
- Open the Map tab to see everything you have captured as a constellation of linked stars.
