Clearform reads your intervals.icu data back to you: how ready you are today, what the next two weeks ask of you, and where your fitness is heading. In 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 out there: deep, precise, endlessly configurable. It answers "what is my data". Clearform answers the question you actually wake up with: how am I, and what should I do today? It reads your data through the official intervals.icu API and does the meaning work, with ranges, baselines and verdicts, the moment you unlock your phone.
Your intervals.icu account stays the single source of truth. Clearform reads it, it does not replace it.
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.
Clearform is built by an athlete who loves the platform. It is not affiliated with or endorsed by intervals.icu.
Form on a labeled gauge with a calm verdict for the day. HRV, resting HR and sleep judged against your own 30-day baseline, not someone else's. No scary arrows, no black-box scores: every verdict shows the numbers behind it.
One dash per session, colored by sport. Solid is done, faded is planned, races glow. Swipe between the 14 days behind you, around you and ahead of you.
A fitness curve and a fatigue line, captioned in plain language so the chart explains itself. Flip to six months for the long view.
Planned sessions draw their structure: warmup, reps, recoveries, cooldown, sized by time and colored by effort. Finished ones show the stats that matter and your time in zones. The deep analysis stays one tap away in intervals.icu.
Slide a session to another day in two taps. Mark yourself sick, injured or on holiday, drop a note, and it syncs straight back to your intervals.icu calendar and feeds tomorrow's verdict.
Your next race sits one glance away with a live countdown, and Clearform projects your Form day by day so you know how you will land on the start line.
Clearform runs entirely in your browser. Your personal API key is stored on your device, and every request goes directly from your phone to intervals.icu. Forget the key anytime with one tap.
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 works fine, and if you train with Garmin, Runna, Rouvy or similar, chances are your data already flows in.
In intervals.icu, open Settings, find Developer, and copy your personal API key. A handful of taps, no forms. 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 away.
