The best free AI workout apps in 2026

Updated 10 July 2026

Here is the honest version most roundups skip: truly free AI coaching barely exists, because building and rewriting a plan for you costs money to run. So free means one of two things. Hevy is genuinely free forever, but it is a tracker, so you design the plan yourself. The AI coaches, Ionik Health, Fitbod, Zing, Freeletics, give you a free trial instead, and Ionik Health's 14 day trial is the longest, so it is the most real coaching you can use before paying.

All prices were verified against official sources on the date above. Below, the table shows the free tier or trial for each so you can see exactly what free buys you.

Free tier versus free trial

The apps in detail

Ionik Health

Ours

AI coach that programmes your week and rebuilds it from what you log.

Ionik Health is built around one loop: the coach writes your week, watches every set you log, and rewrites next week from how you actually trained. Missed days slide forward instead of piling up, and you can ask the coach why anything is in your plan. It is the newest app on this page, with the smallest track record, and we are its developers, so weigh this entry accordingly.

Strong at

  • Weekly plan rebuilt automatically from your logged sets, effort, and notes
  • Conversational coach that explains and adjusts the plan on request
  • Missed sessions reschedule without guilt or catch up debt

Worth knowing

  • Newest app in this comparison, smallest community
  • No wearable integration yet

Price: $9.99 per month or $79.99 per year on the US storefront (£9.99 and £79.99 in the UK), 14 day free trial. We are the developer.

Hevy

Social workout tracker and gym log. Not an AI coach.

Hevy is not an AI training app and does not pretend to be: it is the best pure workout tracker on either store, with a generous free tier and the cheapest paid upgrade here. If you already know how to programme your own training, Hevy plus your own plan is a great, honest combination. If you want the plan built and progressed for you, it is the wrong category.

Strong at

  • Best in class logging experience (4.9 stars on iOS)
  • Genuinely usable free tier, unlimited logging
  • Cheapest paid tier here, with a lifetime option

Worth knowing

  • No plan generation, no coach, no progression logic
  • You bring the programme; it records it

Price: Free tier; Hevy Pro $2.99 per month, $23.99 per year, or $74.99 lifetime.

Fitbod

Algorithmic session generator built on recovery state and equipment.

Fitbod is the most established algorithmic trainer: each session is generated from your recovery state, equipment, and history, and the exercise library is excellent. It builds workouts one session at a time rather than programming a coherent week, and there is no coach to ask why. Prices rose in 2026 to $15.99 per month and $95.99 per year.

Strong at

  • Recovery aware exercise selection for every session
  • Huge, well filtered exercise library
  • Mature, polished app with a massive user base (4.8 stars on iOS)

Worth knowing

  • No conversational coach and no way to ask why
  • Session by session generation rather than a planned week
  • No free tier, and 2026 pricing is up from $12.99 and $79.99

Price: $15.99 per month or $95.99 per year (2026 pricing), 7 day free trial.

Zing AI

AI general fitness trainer with camera based form feedback.

Zing stands out for Zing Vision, which watches your form through the phone camera, and for daily readiness check ins that tune the plan. The trade offs: pricing runs through quiz funnels and promo offers that vary widely, many recent Trustpilot reviews cite billing and cancellation problems, and the strength programming is general fitness depth rather than serious progression.

Strong at

  • Camera based form feedback is a real differentiator
  • Daily readiness check ins adjust the workout
  • Body scan and mobility features beyond lifting

Worth knowing

  • Opaque promo funnel pricing; published store prices are $18.99 per month and $59.99 per year
  • Many recent Trustpilot reviews cite billing and cancellation problems
  • Light on serious strength programming

Price: $18.99 per month or $59.99 per year at published store prices; promotional funnels vary.

Freeletics

Journey based AI coach with bodyweight and HIIT roots.

Freeletics is the veteran here, strongest for home and bodyweight training with structured journeys that adapt as you complete sessions. It bills in 3 to 12 month blocks rather than monthly, and its barbell strength depth is thinner than its HIIT heritage, so lifters usually outgrow it.

Strong at

  • Excellent no equipment and home training
  • Cheap on the 12 month plan at $74.99
  • Long established with a large user base

Worth knowing

  • Minimum 3 month commitment; no monthly option
  • Programme journeys rather than a coach that replans your week
  • Barbell strength programming is comparatively thin

Price: $34.99 per 3 months or $74.99 per 12 months; 14 day money back guarantee.

Common questions

Are there any truly free AI workout apps?

Almost none. Real AI coaching, a plan built and rewritten for you, costs money to run, so it lives behind a subscription. The one genuinely free option here is Hevy, but it is a tracker, not a coach, so you still write the plan yourself. The AI coaches give you a free trial instead.

What is the catch with a free AI workout app?

Usually the word free means one of two things: a free tracker with no coaching, like Hevy, or a free trial that turns into a subscription. Neither is a trick, but they are different. Decide whether you want free logging forever or the most free coaching before you pay.

Which AI workout app has the longest free trial?

Ionik Health, at 14 days, is the longest here, double Fitbod's 7 day trial. That is the most real AI coaching you can use for free: a full plan built, run, and rewritten from your logs before you decide whether to pay.

Is Hevy's free tier enough on its own?

If you already know how to program your training, yes, Hevy free is excellent and unlimited. If you want the plan built and progressed for you, no free tier does that; you need a coach, and the free way to try one is a trial like Ionik Health's.
