# Install the apps

> Install Continual on your iPhone through TestFlight, and on your Mac from its disk image.

Continual runs on your iPhone, on your Mac, and in any browser. Get each app from the
[download page](/download), then sign in with the same account you use on the web.

## Install on iPhone

The iPhone app is in early testing, so it installs through TestFlight, Apple's app for trying apps
before they reach the App Store. It needs iOS 26 or later.

<Steps>
  <Step title="Install TestFlight">
    Open the App Store on your iPhone, search for **TestFlight**, and install
    it.
  </Step>
  <Step title="Open the Continual link">
    On your iPhone, open the download page and choose **Get it on TestFlight**.
  </Step>
  <Step title="Accept the invitation">
    TestFlight opens and shows Continual. Choose **Accept**, then **Install**.
  </Step>
  <Step title="Open Continual">
    Open Continual from your Home Screen and sign in.
  </Step>
</Steps>

## Install on Mac

The Mac app gives Continual its own window and a shortcut that works from any app. With your
permission, Continual Computer, a helper that comes with the app, lets Continual see and use your
Mac.

<Steps>
  <Step title="Download the disk image">
    On your Mac, open the download page and choose **Download for Mac**. Your
    browser saves `Continual.dmg`.
  </Step>
  <Step title="Open the disk image">
    Open `Continual.dmg` from your Downloads folder.
  </Step>
  <Step title="Drag Continual to Applications">
    In the window that opens, drag **Continual** onto **Applications**.
  </Step>
  <Step title="Open Continual">
    Open Continual from your Applications folder. If macOS asks whether to open
    an app downloaded from the internet, choose **Open**. Then sign in.
  </Step>
  <Step title="Grant Continual Computer its permissions">
    When macOS asks to give **Continual Computer** a permission, open System
    Settings and turn it on. **Accessibility** lets it read and use other apps;
    **Screen & System Audio Recording** lets it see the screen.
  </Step>
</Steps>

<Callout type="tip" title="Turn a permission on later">
  Open System Settings › **Privacy & Security**, choose **Accessibility** or
  **Screen & System Audio Recording**, and turn on **Continual Computer**.
</Callout>

## Use Continual in a browser

Continual's web app needs nothing installed. Open the download page and choose **Open Continual** on any computer, including Windows and Linux.
