# More resources

App downloads, the reference Products and source repositories.

For what to `npm install` and why, see [Packages & tools](packages.md). For
chains, endpoints and the network preset, see
[Networks & endpoints](networks.md).

!!! note "Paseo Next v2"
    This page covers the PCF Products Devnet (`devnet` preset). For Paseo Next v2 (`paseo` preset), see [Get the Polkadot App](../index.md#get-the-polkadot-app) or [Install Polkadot Desktop and Pair](../get-started/index.md).

## 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](https://appdistribution.firebase.dev/i/f3b79521380b40b9) to get each new build automatically |
| Android (manual APK) | the [latest Android release](https://github.com/Polkadot-Community-Foundation/polkadot-android-community/releases/latest) |
| iOS (TestFlight) | [join the TestFlight beta](https://testflight.apple.com/join/HnBX59vz) |
| Desktop (macOS / Windows / Linux) | the [latest desktop release](https://github.com/Polkadot-Community-Foundation/polkadot-desktop-community/releases/latest) |
| 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](https://faucet.polkadot.io).

## Reference Products to open

These apps run on the Devnet. They are developer-preview examples, not audited
production applications.
