Beta · iPhone and Apple Watch

Run it first

Moonstride is nearly ready, and we'd love runners to put it through its paces before anyone else. Run with it for two weeks, tell us what works and what doesn't, and help shape the coach before it reaches the App Store.

What we'll ask of you

Free during the beta. Needs an iPhone on iOS 26 and an Apple Watch you run with.

  1. 1

    Get the beta

    Tap the button on your iPhone. TestFlight, Apple's app for betas, installs Moonstride.

  2. 2

    Connect Apple Health

    Moonstride reads your runs, sleep and heart rate. It's read-only, and there's no account to make.

  3. 3

    Run for two weeks

    Record every run with your Watch, as normal. Try the things below as you go, and tell us how it went.

Why another running app

Not another feed

Most running apps want an account, your runs on their servers, and a subscription before they'll coach you. Moonstride starts from the runs already on your iPhone, and keeps them there.

  • Your history on day one

    Every run your Watch has ever recorded is already in it: personal bests found inside them, your current form, and a plan built from where you really are. Nothing to import and no starting from zero.

  • A coach, not a feed

    Other apps show you numbers and a leaderboard. Moonstride tells you what the numbers mean, then talks you through the next run, hills and all.

  • Keep your Workout app

    Record runs as you always do. They stay native Apple workouts, still close your rings and still count toward challenges.

  • Nobody's watching

    No account, no public map of where you run and no server for your runs to sit on. They never leave your iPhone.

Questions

Is it free?

Yes, everything is free during the beta.

Do I need an Apple Watch?

It's made for one. Your runs come from the Watch's Workout app, through Apple Health, so without a Watch there's very little for Moonstride to read. You'll also need an iPhone on iOS 26.

Android?

Not for now. Moonstride is built around Apple Watch and Apple Health.

What do you see of my data?

Your runs, sleep and heart rate stay on your iPhone, beta or not. We only see what you choose to send: feedback and screenshots from TestFlight, crash reports if you allow them, and your emails.

What happens when it launches?

The App Store version installs over the beta, and your runs are still in Apple Health as they always were. Beta builds expire after 90 days, and TestFlight installs each new one for you.

See you out there

Thanks for running with us. Every run you log and every note you send makes Moonstride better for the next runner.
