Squad vs Squad every week

Your squad faces one opponent each week. Every member adds points. Train whenever — your effort moves the score.

Any sport. Fair competition.

A runner, a cyclist, a lifter, and a rower on the same squad — competing on equal terms. Your effort is the score.

Your effort is visible

Every workout you log appears in your squad’s feed. Teammates react. The scoreboard moves. No more invisible workouts.

Win matches. Climb the table.

Matches build your squad’s position. Seasons end with champions, final scores, final trophies.

Riina app — League 1 matchup screen

Built on what actually drives people

Find your squad. Compete together. Experience what makes training better, people are counting on you.

People, not algorithms

Your squad sees your effort and depends on it. That's what makes people show up differently.

Team sport, solo schedule

Traditional team sport requires coordinated schedules. Riina doesn't. Train whenever.

Bigger than yourself

Training for squad outcomes changes everything about how people show up.

Same effort, same score

Heart rate zones relative to your personal max. The playing field is effort, not sport.

The way in is through someone already in

Built on trust, not traffic.

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.

Got questions?

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.
