A screen-free bracelet: why use one

Why no screen

• Fewer distractions. No notifications, activity rings or flashing numbers. The bracelet works in the background while you get on with life.
• Sleep undisturbed. Nothing lights up when your wrist moves at night. Especially useful if sleep tracking is your priority.
• Longer battery life. A screen uses substantial energy. Without one, tri runs for up to 15 days per charge.
• Light and soft. A fabric strap keeps the module against your wrist. Wear the bracelet continuously.

Where do I view the data?

In the app. Each morning, it summarizes sleep, recovery and strain in three scores with daily guidance. Want detail? Explore sleep stages, heart rate, HRV, workouts and habit insights there too.

No need to check the app hourly: the bracelet stores up to 30 days of data and transfers it when your phone is nearby. Ask the Russian-speaking assistant if anything is unclear. It sees your measurements and answers in context.

Who it won't suit

If you need time, notifications, a running map and wrist payments, choose a watch. Many people wear both: a watch on one wrist, tri on the other. The watch handles everyday tasks; the bracelet tracks sleep, recovery and strain.

Screen-free bracelets on the market

The American brand WHOOP popularized the idea: a subscription-based, screen-free bracelet estimating recovery and strain. It is not officially shipped to Russia, so we created tri, with the same philosophy, Russian support, ruble payments and an assistant that sets bracelet alarms.
