Clearform takes the training data you already have in intervals.icu and turns it into a clean, fast, mobile view. Readiness now, the next 14 days ahead, your fitness trend behind it. 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. What it never tried to be is a pretty phone app. Clearform fills exactly that gap. It reads your data through the official intervals.icu API and shows the essentials the moment you unlock your phone: how ready you are today, what the next two weeks look like, and where your fitness is heading.
Your intervals.icu account stays the single source of truth. Clearform reads it, it does not replace it.
Planning depth, interval analysis and power tools stay where they belong: in intervals.icu. Clearform is the quick daily glance.
Clearform is built by an athlete who loves the platform. It is not affiliated with or endorsed by intervals.icu.
One dash per session, colored by sport. Solid means done, faded means planned. Tap a day to see what is on it.
Form, Fitness and Fatigue on a clear gauge. HRV, resting HR and sleep with quiet in-range verdicts.
A fitness curve and fatigue line with captions in plain language, so the chart explains itself.
Slide a planned session to another day in two taps, synced straight back to your intervals.icu calendar.
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, scroll to Developer, and generate a personal API key. That key is your login.
Go to app.clearform.icu, paste the key once, and add Clearform to your home screen. From then on it is one tap away.
