Most fitness apps assume you can already do a burpee. Unfitly starts by finding out what you can do today — then asks for the smallest thing that still counts.
Free on the App Store · iPhone, iOS 17 or later · built for adults. The check runs in your browser if you'd rather not download anything first.
If one flight of stairs leaves you holding the bannister, a programme built around burpees isn't cautious — it's useless. Unfitly is built for the cohort that gets skipped: sedentary, prediabetic or diabetic, carrying weight, and tired of apps that open with a shirtless before-and-after.
You can take the check in your browser before you download anything. Eight safety questions and twelve about what you can do — about two minutes — and you get your functional capacity in METs — anchored to what that means in practice, like carrying the shopping in from the car. Some people find it lower than they expected. That's the point: you can't plan from a feeling.
Then thirty seconds on a chair, once a week. It's the number that moves before the scale does — and watching it climb is what keeps people going.
Real screens, not mockups — every one of these is the shipping app.
Set a goal with a date — a wedding, a trip, a grandchild — and if you're not going to be ready, it says so, and says how far off you really are. At six weeks, three months and half a year it writes you a short account of what changed, built from your own numbers, including the weeks that went badly. A record that can only report good news is a marketing asset, not a record.
Everything that measures you is free and stays free. Pro buys the writing-up — and only after the app has shown you a gain in your own numbers.

In the US, Pro is US$9.99 a month, US$49.99 a year, or US$79.99 once — your own store shows its local price. The one-off is shared with your family and never renews. Nothing you have already measured is taken away if you don't buy it.
Written for the same person the app is: plain, specific, and free.
Fitness is the most crowded category on the store, and almost all of it is built for people who are already fit. The users with the most to gain — and the highest rates of diabetes and obesity — get a scaled-down version of an athlete's app. Unfitly measures instead of motivating, and refuses to flatter. Every movement is priced from the 2024 Adult Compendium of Physical Activities; nothing in it is invented.
No. It starts by measuring what your body can currently do, then asks for the smallest useful thing — a two-minute walk after a meal, standing up out of a chair. Most fitness apps assume you can already do a burpee.
Never. Weight says almost nothing about what your body can do; two people at the same weight can be a decade apart in capacity. Unfitly measures capacity instead.
No. It measures functional capacity and suggests general activity. It does not diagnose, screen or treat, and it does not replace your doctor. If you report chest pain or a recent cardiac event it withholds the exercise programme and tells you to speak to a clinician.
The app is free, and the parts that measure you stay free forever — the assessment, your capacity score, the daily programme, the weekly re-test and the one-page summary you can hand a doctor. Unfitly Pro adds two things: the written record of what changed, and the full PDF of every reading with dates. In the US it's US$9.99 a month, US$49.99 a year, or US$79.99 once; other stores show their own local price. You're never asked for money until a weekly check has shown you a gain.
