Fitless vs Hevy: generate the workout or track it?
Fitless and Hevy solve different problems. Hevy is a tracker: you build the routines and it offers the best manual set logging in the category, with a strong social feed. Fitless is an AI personal trainer: it builds the plan from an analysis of your body, logs your sets, and suggests when to add weight. If the question is who builds your workout, the answer decides which of the two makes sense for you.

The core difference: who builds the workout?
In Hevy, the workout is your job. You create routines exercise by exercise (or import a friend's) and Hevy handles the logging brilliantly: a fast interface, per-exercise history, personal records, and charts. If you already have a plan from a coach or know how to build your own, that is all you need.
In Fitless, the plan is generated by AI from your goal, your available equipment, and the photo-based body analysis. Set logging is there too (including on Apple Watch), with one extra layer: the AI follows your history and suggests the next load when you are ready to progress. You do not need to know how to program training to start well.
Free plans: what does each one unlock?
Hevy's free plan is one of the most generous among trackers: unlimited workout logging, with limits on saved routines and advanced history features, unlocked in Hevy Pro (between US$ 2.99 and 4.99 per month depending on region, with a lifetime purchase available). Fitless, during launch, unlocks everything without a subscription: workout generation, body analysis, plan import, Apple Watch, and social. The difference is that Hevy's free model is permanent by design, while Fitless's is a launch condition.
Social: global community or competition between friends?
Hevy's feed feels like a social network for workouts: you follow people, like sessions, and browse other users' routines, with a large global community. Fitless's social layer is closer to a game between friends: daily streaks, a weekly ranking for your group, and a collectible profile card with skins and stickers unlocked by training. Different propositions: broad audience on one side, close-circle competition on the other.
Verdict: which one should you choose?
Choose Fitless if...
- You want the AI to build and progress the workout for you
- You want to track body composition from photos
- You are migrating from a paper sheet, PDF, or another app
- You prefer competing with friends over following an audience
Choose Hevy if...
- You already have your training plan figured out

- You value a large global community
In 2026, with Fitless free during launch, you can try both without spending anything and decide in practice.
Frequently asked questions
Does Hevy build workouts with artificial intelligence?
No. Hevy is a tracker: routines are created manually by you or copied from other users. Support tools like a warm-up calculator exist in the Pro version, but building and progressing the plan remains manual.
Can I migrate my Hevy routines to Fitless?
Yes. Record the screen of your routines in Hevy, or export your data and send it as an image, PDF, or spreadsheet: Fitless's AI rebuilds the plan with exercises, sets, and loads, ready to continue where you left off.
