# Install Summit

> Put Summit on your iPhone while it's in early testing.

Summit isn't in the App Store yet. Until TestFlight opens, you install a test build from a Mac with a free app called Sideloadly and your Apple ID.

You need an iPhone on iOS 17 or later, a Mac, and a USB cable.

::::steps
### Get the build

Get the latest test build, a file named `Summit.ipa`, from the Summit team. If you can see the Summit repo, it's the `Summit-ipa` file at the bottom of the latest **Build** workflow run.

### Install Sideloadly

Download it from sideloadly.io and open it on your Mac.

### Connect your phone

Plug your iPhone into the Mac, unlock it, and tap **Trust** when it asks.

### Install the app

Drag `Summit.ipa` into Sideloadly, enter your Apple ID, and click **Start**. Apple may text you a code to finish signing in.

### Turn on Developer Mode

On your iPhone, go to **Settings → Privacy & Security → Developer Mode**, turn it on and restart when asked.

### Trust the app

Go to **Settings → General → VPN & Device Management**, tap your Apple ID and tap **Trust**. Summit now opens from your home screen.

:::note[Why your Apple ID]
Sideloadly signs the app with your Apple ID so your iPhone will run it. You type the Apple ID into Sideloadly on your own Mac. If you'd rather keep your main account out of it, a spare Apple ID works too.
:::

## Limits of a free Apple ID

- **The app stops opening after 7 days.** Install it again with Sideloadly to reset the clock. Your walks and your peak stay on the phone.
- **Three test apps at a time.** Summit counts as two, one for the app and one for its widget.

:::tip
To get a newer build, install the new `Summit.ipa` the same way. It replaces the old one and keeps your data.
:::

When Summit moves to TestFlight, you'll install it from Apple's TestFlight app instead, and each build will last 90 days.
