Your squad sees your effort and depends on it. That's what makes people show up differently.
Traditional team sport requires coordinated schedules. Riina doesn't. Train whenever.
Training for squad outcomes changes everything about how people show up.
Heart rate zones relative to your personal max. The playing field is effort, not sport.
Riina doesn’t grow through ads. It grows through people who already know what it’s worth. Every member got in because someone vouched for them. That’s the point.

Here’s what our users have to say about Riina.
Same person. Same workouts. Completely different outcome.
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.
