Three taps to your first session.

TestFlight is Apple's official app for trying builds before they hit the App Store. Setup is quick, and every update lands automatically.

  1. Open the invite

    Tap Join the beta on your iPhone to open the Chalky invitation in TestFlight.

  2. Install TestFlight

    If you don't have it yet, grab Apple's free TestFlight app — then accept the invite.

  3. Open Chalky

    Install Chalky from TestFlight and start logging. Your feedback goes straight to the team.

Get in early. Lift with intention.

Beta builds ship often, and what you tell us shapes the next one. Join now and train with Chalky while it's still being written.
