You already collect the data. Clearform turns it into answers: how ready you are right now, what the next two weeks ask of you, and proof your fitness is building. Plain language, on your phone, in under ten seconds. No new platform, no new account.
Requires a free intervals.icu account.
intervals.icu is one of the best training analytics platforms there is: deep, precise, endlessly configurable. But depth takes time, and most mornings you just want the answer. Clearform connects through the official API and turns your own data into exactly that: how recovered you are, whether today should be hard or easy, and whether all that training is actually working. Ten seconds, one glance, on with your day.
Your intervals.icu account stays the single source of truth. Clearform reads it live: nothing to migrate, nothing to keep in sync, nothing to maintain twice.
The deep dives and power tools stay where they belong, in intervals.icu. Clearform is the layer on top that tells you what it all means, before you have finished your coffee.
We build Clearform because we train with intervals.icu ourselves and love it. Independent, unaffiliated, and made with a lot of care.
Open the app and get a straight answer: push today, or take it easy. Your Form, HRV, resting heart rate and sleep are checked against your own normal range, so a quiet "in range" means you are genuinely fine. No red arrows shouting that you are broken, no mystery score to decode, just a clear call you can trust, with the numbers right there whenever you want proof.
Every session is a dash, colored by sport: solid is banked, faded is still to come, race days glow. One look tells you where you stand and what is waiting, no calendar digging. Go ahead, swipe the strip.
Your fitness climbing while fatigue settles after the big weeks: proof your training is working, in one calm picture. Zoom out to six months and see how far you have come, with captions in plain language so you never decode a chart before breakfast.
Tomorrow's session, drawn to scale: the warmup, the work, the recoveries, each block colored by how hard it will bite. You know exactly what is coming, so you can show up ready to give it everything. And when it is done, your stats and time in zones land in the same place, one tap from the full deep dive in intervals.icu.
Tuesday's tempo lands on Thursday in two taps. Caught a cold, off on holiday? Mark it right in the app. Everything syncs straight back to your intervals.icu calendar, and tomorrow's verdict takes it into account instead of guilt-tripping you.
Your next race sits at the top of the app with a live countdown, and Clearform projects your Form forward, day by day, through the taper. No more hoping it works: watch yourself getting fresher as the start line approaches.
Clearform runs entirely in your browser. Your personal API key lives on your device, and every request goes straight from your phone to intervals.icu. No Clearform server ever sees your training data, because there is no Clearform server. Forget the key anytime with one tap, and it is gone.
No middleman. There is no Clearform server reading, storing or seeing your training data. The site you are on now only serves this page.
Clearform builds on it, so you need one. The free tier is plenty, and if you train with Garmin, Runna, Rouvy or similar, your data is probably already flowing in.
In intervals.icu: Settings, Developer, copy. A handful of taps, no forms, no new password to invent. That key is your login, and it never leaves your phone.
Open app.clearform.icu, paste the key, add Clearform to your home screen. From then on it opens signed in: one tap from lock screen to verdict.
Free during early access. All you need is an intervals.icu account.
