Install the app

Prow is a web app you can install (a PWA). There is nothing to download from an app store. Once installed, Prow opens full screen from your home screen or dock, and updates arrive by themselves.

iPhone and iPad

You need Safari on iOS 16.4 or later.

1. Open Prow in Safari

   Other browsers on iPhone cannot install apps with push.

2. Tap Share

   The square with an arrow, at the bottom or top of Safari.

3. Tap Add to Home Screen

   Scroll down the share sheet if you do not see it. Tap Add.

4. Open Prow from the home screen

   Sign in again. The installed app has its own storage.

Android

1. Open Prow in Chrome

   Edge and Brave work too.

2. Tap Install app

   It is in the browser menu, or in the banner Chrome shows.

3. Open Prow from your home screen

Desktop

Use Chrome, Edge, Brave or Arc. Click the install icon at the right of the address bar, then Install. Prow opens in its own window and shows up in your dock or Start menu.

After you install: restore your keys

An installed app can count as a new device, with its own storage. Your trading keys from the browser may not be there.

You have two ways to get trading again:

• Passkey backup. If you turned it on, Prow shows Turn on trading. Tap Use passkey. No wallet signature needed. See Back up keys with a passkey.
• Sign once. Without a backup, tap Approve in your wallet in the same window. Your wallet signs a new trading key for this device, one signature per venue. You can also do it later: tap Turn on trading on Portfolio, or in Settings > Venues.
