Get the app
Section titled “Get the app”The Polkadot app is where people use Products, on mobile and desktop. The web gateway works in any browser if you only want to look around.
These are devnet builds. The Polkadot releases on Google Play and the App Store connect to a different network and do not work with these docs.
| Platform | Where to get it |
|---|---|
| Android (recommended) | join the tester group to get each new build automatically |
| Android (manual APK) | the latest Android release |
| iOS (TestFlight) | join the TestFlight beta |
| Desktop (macOS / Windows / Linux) | the latest desktop release |
| Web gateway (no install) | https://dev-dot.li |
On Android, the tester group is the easiest route. Accept the invitation with a Google account and you are notified of each new build.
To install by hand instead, take app-polkadot-devnet.apk (~200 MB) from the
latest release and allow installs from unknown sources. The same APK runs with
or without Google Play services.
iOS builds are only distributed through TestFlight. The first build of each version reaches the group once Beta App Review approves it.
If an account cannot submit a transaction, it probably needs devnet funds. Get them from the faucet.
