Everything you need to know before you join.

Riina is a team sport for people who work out solo. Connect any wearable and our AI turns your heart rate into effort points — so running, lifting, swimming, and CrossFit all compete on the same scoreboard. Join a squad, play a new 7-day match every Monday, and battle through a 5-week season against rival teams. Every workout you crush — or skip — your team feels it.

Apple Watch, Garmin, Whoop, Oura, Polar, Google Pixel, Fitbit, and any other wearable that syncs to Apple HealthKit or Android's Health Connect. If it tracks heart rate and syncs to your phone's health app, Riina reads it.

Leagues run from 2 up to 12 teams. Each team has 1–5 active members, plus an unlimited practice squad.

Your base score comes from the time you spend in different heart-rate zones during a workout — higher-intensity zones earn more points than lower ones. Our AI then validates and adjusts scoring based on overall intensity to keep competition fair. Your personal zones are calculated from your health profile (resting and max heart rate, ventilatory thresholds), so keeping it up to date keeps your scoring accurate.

Yes. Your raw health data — heart rate, GPS, weight and the rest — stays on Riina's own servers (hosted in the EU) and is never sold or shared for advertising. We use a small number of vetted providers (e.g. hosting and push notifications) strictly to run the app, under data-processing agreements. See our Privacy Policy for the full list.
