About Trimetra

Miss a session, fall ill or pick up extra load, and the plan adapts automatically.

Thresholds, intensity and load in future weeks adjust with it, so the plan fits your form better and better.

Ask your question in your own words (“my legs are sore, should I train?”, “slept badly”, “I feel strong”) and you get an answer from your own data, not from a generic article. What you report counts immediately: sore legs, illness or a short night adjust today’s plan straight away. Your question is recognised on your own device, and we do not keep its text unless you send us a question yourself.

Is your recovery dropping? Then Trimetra favours endurance or rest over quality.

Start your session in the app and Trimetra records time, distance and pace via GPS. A heart-rate strap or power meter connects straight over Bluetooth, and your planned session runs alongside as guidance: you see what you are doing now and what comes next, with a spoken cue and a beep at every block change. Pick a route from your library to go with it and you see and hear the turn cues along the way, with a heads-up as soon as you drift off the route. In the iOS app the recording keeps running in the background, so the screen can go off. After you stop, the entry is ready: top it up and save.

In the run-up to the race you also get a pacing plan for race day itself: pace bands per segment and fueling advice matched to the expected duration.

For outdoor sessions the weather counts: warm days do not distort your fitness trend, in the heat you get extra drinking advice, and you can see how used to training in the warmth your body already is.

The projection uses physics on your power and your weight rather than a lookup table, and says honestly when a climb is not within reach yet and what is missing. You get the elevation profile, a pacing breakdown per kilometre and a what-if simulation for lighter or stronger. Make it your goal climb and Trimetra projects your time towards your goal date on your own measured power trend: bounded, and only when that trend is genuinely there.

Trimetra also recognises climbs in your own rides: ride a hill twice and it appears by itself with your own times and PR. So even without a catalogue climb nearby you can see where your hills are, with their name and place, and every attempt listed with its date and watts per kilo.

You see the route on the map, save favourites in your own library and export them as a GPX file or straight to your bike computer.

Some finds only show up in frost or warm weather, and on the market you trade what you have twice. It is on by default and can be switched off in your profile, under Extra features.

The app distinguishes pool and open-water swimming, so your calibration stays clean while open-water sessions still count towards your load.

Per exercise you get an estimated 1RM and advice for the next session that moves with how the previous one went: felt light means room to build, all out means hold or ease back.

With the tracker off, you see none of it.

Fully opt-in and only visible when it is relevant for your profile; the data stays yours.

Swimming also shows your best pace per 100 metres. Cycling shows your highest power per duration, from a one-second peak to a full hour, the most elevation in one ride, your climbing power and your fastest time on each climb. Strength shows your estimated 1RM per exercise and your most reps with body weight. Every record shows the date and your top 5, so you can see whether a best mark is fresh or has stood for a while.

You turn each type on or off separately, at a time you choose.

It is a subscription, not a one-off export: when your plan shifts, your calendar shifts with it. The feed contains only the session type, the duration and the execution band of your own plan; health data does not go into it. The link is personal, so keep it private.
