Join the Stamio beta
Stamio brings GPS-watch training metrics to your Apple Watch: VO2 max, training load and status, readiness, energy, sleep score, race predictions, and a training plan that adapts to you. Before its App Store release, we're looking for testers.
Who we're looking for
You need an Apple Watch (Series 6, SE 2nd generation, Ultra or newer, on watchOS 11 or later) and an iPhone on iOS 18 or later, and be 18 or older. Every kind of runner counts, especially:
- women, seniors (60 and over) and beginners;
- regular runners as well as competitive ones;
- US runners who think in miles;
- people who do other sports (cycling, swimming, strength…);
- people who also wear another watch (Garmin, Coros, Polar, Suunto…) every day: it's the best way to check the calculations.
What you'll do
- Install Stamio with Apple's free TestFlight app and wear your watch day and night for 3 to 4 weeks.
- Turn off automatic updates for Stamio in TestFlight (Stamio › Automatic Updates), then install each new version when you're not in a workout: an update installed during a workout stops it (Stamio then offers to resume it, and to merge the two parts).
- Tell us what you think: what you love, what confuses you, what looks off (TestFlight's "Send Beta Feedback" button, or by email).
- If you want, send an export of your calculated values from the app, with your explicit consent: never your raw measurements, your location or your name. Details are in the privacy policy, "Beta version" section. If you live in the United States, see also our Consumer Health Data Privacy Policy (stamio.app/health-data-privacy.html).
What's in it for you
Stamio before anyone else, 1 month of Stamio Pro free at launch, then the Founders price through January 31, and a say in what it becomes.
Join the beta
The beta is open: open this link on your iPhone, it installs Stamio with TestFlight (Apple's free app for betas).
To claim your launch offer, leave your email on the home page (it takes ten seconds).
Stamio is not a medical device: its values are estimates to help you train.
