Hi Product Hunt! 👋

I'm Petr, and I built Aurin because I had all the data from my watch and ring but no app told me what to do with it that day, across riding, running, swimming and the gym.

What Aurin does:

• Today, on one screen: readiness weighed against your own normal, sleep, strain with a target for the day, HRV, and a short line from the coach every morning

• A plan that adapts: ride, run, swim and gym in one week. Follow a plan, plan it yourself or let the AI do it, and sync with Intervals.icu

• Gym built for today: a workout from rested muscles and your gym's equipment; training mode fills in last time's weights and keeps the rest timer on your lock screen and Apple Watch

• Nutrition that follows training: train harder and you get more to eat; log from a photo, a barcode or a search

• An AI coach that knows your data: ask how to train today or how to adjust your week; when it proposes a workout, you confirm it and it lands in your plan

Works with Apple Health, Google Health, Intervals.icu , Ultrahuman Ring, WHOOP and Wahoo.

Privacy: data is stored in the EU and is never sold or used to train AI models. You can pause health data or delete your account in the app.

Aurin is in free testing on TestFlight before the App Store: https://testflight.apple.com/join/dk1nZQfa (if it's full, join the waitlist at https://aurin.health). I'd love your honest feedback: what's confusing, what's missing, and what you'd want the coach to do next.

Thanks for checking it out! 🙏
