The short answer
Pick by the job you need done
For gym weights chosen from your history, try Fitbod first, or Gravl if you want to run the session from your watch. For a person writing your plan, Future matches you with a coach at $199 a month, and Ladder gives you a coach's team program for much less. Freeletics suits bodyweight training at home, Zing adds camera feedback on your form, and Hevy is the free logger with no AI at all. Aion, which we make, fits a week that keeps changing, and its plan is free.

How the apps were chosen and what was checked
The shortlist started with apps that describe themselves as an AI trainer, AI coach or AI workout planner. Then came three that answer a different question: two that put a human coach behind the plan, and a plain logger for people who want no AI. Each app is here for one need. Fitness AI and JEFIT also pick weights from your history, and they were left out only to keep one app per need.
On October 20, 2026 we read each app's US App Store listing, including its In-App Purchases section, and the developer's own site or pricing page. Ratings and rating counts come from Apple's public lookup for the US store, with the average rounded to one decimal. We did not test the apps for this guide, and nothing here comes from reviews or other comparison sites. Where a site and the App Store list different prices, the card gives both.
- Price: the main subscription in US dollars, with its period, as the developer or the App Store lists it.
- Free: what you can use without paying, in the listing's or the site's own terms.
- Platforms: iPhone, Apple Watch, Android and the rest, from the listing and the developer's site.
- Languages: the languages the App Store listing gives for the app itself.
- What the AI does: taken from the app's own description, and attributed to it where it matters.
Prices change, App Store and web prices can differ, and introductory offers vary from one account to the next. Each card carries the date its facts were read.
The picks
Best for automatic gym weights
Fitbod
Fitbod builds each session from your goal, your equipment and what you lifted before, and sets the exercises, sets and weights for you. Its site says it launched in 2015 and counts 15 million downloads, and it has the largest US rating count in this guide. If you lift in a gym several times a week and want the next number chosen for you, this is the one to try first.
Where it is strong
- Picks exercises, sets and weights for every session, and the listing says it learns from the edits you make
- More than 1,000 exercises with multi-angle video, per the listing
- Home workouts with no equipment are covered too, the listing says
- Apple Watch, Android and Wear OS apps, per Fitbod's FAQ
Where it falls short
- After the 7-day trial it is a subscription; neither the FAQ nor the listing describes a free plan
- Trainers answer questions by email, per the listing, while the plan itself comes from the algorithm
- The App Store also lists cheaper plans than the website, so check which price you are paying
- Price
- $15.99 a month or $95.99 a year, per Fitbod's FAQ. The App Store also lists a $12.99 monthly and a $79.99 yearly plan
- Free

- App Store rating
- 4.8 from 287,775 ratings (US)

Best for training from your watch
Gravl
Gravl does the same core job as Fitbod. Its listing says it estimates your one-rep max from your logged history, prescribes the next session from that, and snaps the weight to the plates or stack you actually have. Where it pulls ahead is the wrist: a standalone Apple Watch app that runs a whole session without the phone, plus Wear OS and Garmin apps, according to Gravl's site.
Where it is strong
- Rate a set Easy or Hard and the next prescription adjusts, per the listing
- Weights are rounded to the plates or stack in your gym
- Gravl's site says it turns a routine from a screenshot, a whiteboard photo or a coach's PDF into a workout you can track
- Free to start
Where it falls short
- The watch app, full plans and analytics are on Gravl Premium
- Gravl's own site says it is not a running or cycling coach; strength training is the core
- A much smaller US rating base than Fitbod's
- Price
- The App Store lists $14.99 a month, $34.99 for three months and yearly plans from $59.99 to $89.99. Gravl's site gives no price
- Free
- Free to start, per the listing. Full training plans, the Apple Watch app and analytics need Gravl Premium
- App Store rating
- 4.9 from 5,925 ratings (US)
- Platforms and languages
- iPhone, Apple Watch, Android, Wear OS and Garmin watches. English, Czech, French, German, Italian, Polish, Portuguese and Spanish.

Best if you want a human coach
Future
Future is the one app here where a person writes your program. Its listing says you are matched with a coach who builds the plan around your goals and schedule, checks in, and refines it as you go. That costs $199 a month after a $50 first month, by far the most expensive option in this guide. If what you are missing is a real person who notices when you skip, that is what the money buys.
Where it is strong
- A dedicated human coach builds and adjusts your program, per the listing
- Your coach checks in and follows your progress
- Apple Watch tracking, and an Android app through Google Play, per Future's site
- A full refund if you cancel within 30 days, Future's site says
Where it falls short
- $199 a month is many times the price of any other app here
- No free plan
- The app is in English only
- Price
- $199 a month, per the listing and Future's site. The site offers the first month for $50
- Free
- No free plan. Future's site offers a full refund if you cancel within 30 days
- App Store rating
- 4.9 from 10,742 ratings (US)
- Platforms and languages
- iPhone, Apple Watch and Android. English.

Best for coach-written programs
Ladder
Ladder sits between an app and a personal coach. A human coach writes each week for a team, you join the team that suits your style, and you follow along with in-ear cues, videos and a timer. Ladder's site says plainly that its programs are neither generated by an algorithm nor one-to-one. You get a real coach's programming for $29.99 a month, written for the group.
Where it is strong
- 23 coach-led teams, from bodybuilding and kettlebells to Pilates strength, per Ladder's site
- In-ear coaching, video demos and a built-in timer in every workout
- Food and macro tracking is included in the iPhone app, Ladder's site says
- The highest US rating average in this guide
Where it falls short
- No Android app, per Ladder's site
- The program is the team's; one-to-one coach chat is on the ELITE plan
- Subscription only once the 7-day trial ends
- Price
- Pro is $29.99 a month or $179.99 a year, per Ladder's pricing page. The App Store also lists higher PRO+ and ELITE tiers
- Free
- A 7-day free trial with no payment details taken until it ends. Subscription only after that, per Ladder's site
- App Store rating
- 5.0 from 210,098 ratings (US)
- Platforms and languages
- iPhone, iPad, Apple Watch and a web app. No Android app. English.

Best for bodyweight training at home
Freeletics
Freeletics is the pick when there is no gym. Its listing calls bodyweight HIIT and calisthenics-style sessions classic Freeletics, and the free version gives you 34 of those workouts to keep, which is more free training than most apps here offer. The paid Coach builds a plan from your goals and level, adjusts each workout from your feedback, and can mix in weights, machines or running when you have them.
Where it is strong
- A free version with 34 bodyweight HIIT workouts and more than 100 exercises
- The Coach adapts workouts to your feedback, your time and your setup, per the listing
- Apple Watch control and an Android app
- The app comes in 10 languages
Where it falls short
- The Coach is sold in 3, 6 or 12 month plans; the listing names no monthly option
- Nutrition coaching is a separate Freeletics app, sold as a bundle
- Price
- The Training Coach is sold as 3, 6 or 12 month plans, listed on the App Store from $34.99 to $79.99. A training and nutrition bundle is listed from $49.99 to $89.99
- Free
- 34 bodyweight HIIT workouts and more than 100 exercises, per the listing. The Coach has a 14-day money-back guarantee

Best if you want camera feedback on form
Zing AI
Zing tries to see more of you than the others do. Its listing describes Zing Vision, which uses the phone's camera to track your movement and give technique feedback, and an AI body scan for body composition. A coach in the app checks in on energy, mood and sleep and adjusts the plan. If you train alone and want something looking at your form, Zing is built around that, and Aion has no camera form check at all.
Where it is strong
- Camera tracking of your movement for technique feedback
- Daily check-ins on energy, mood and sleep feed the plan, per the listing
- Home and gym workouts drawn from almost 500 exercises
- Apple Watch support, and Android through Google Play
Where it falls short
- Hard to compare on price: the App Store lists several Zing Premium prices, and the period of each shows in the app
- The body scan report is a separate $19.99 purchase on the App Store
- The listing describes no free plan
- Price
- The App Store lists Zing Premium at prices from $18.99 to $59.99, including a three-month plan at $29.99. Zing's terms say the app's price screen shows the period
- Free
- The listing describes no free plan. Zing's terms say any trial is stated on the price screen before checkout
- App Store rating
- 4.8 from 30,760 ratings (US)
- Platforms and languages
- iPhone, Apple Watch and Android. English, French, German, Portuguese and Spanish.

Best for a plan built around a changing week
Aion Coach
Aion is ours, so read this one with that in mind. It is for people whose week will not hold still. You give it your days, your minutes, your kit and your goal, and it builds the week only from exercises that kit allows. When a logged session goes well, the next one goes up one small step; two misses and it backs off. All of that is free. The membership adds a chat coach: ask for a swap, a shorter session or another day, and a card shows the before and after so you can Apply or Keep.
Where it is strong
- The whole plan is free, progression included, with one exercise swap per workout
- Uses only exercises your kit allows, from a 594-exercise catalog
- Ten calisthenics skill ladders with exit criteria, from the pull-up and dip to the front lever and planche
- Running and HYROX plans
- Injuries and limits you mention are remembered, and moves that aggravate them are eased or swapped
Where it falls short
- iPhone only, and the app is in English
- New, with no US App Store ratings yet
- The chat coach needs the membership
- No camera form check, and no nutrition or calorie tracking
- Price
- Plan free. Coaching membership $3.49 a week, $9.99 a month, $59.99 a year; the annual one opens with 7 free days
- Free
- The whole plan: every workout, every new week, the logbook, progression and one exercise swap per workout
- App Store rating
- Too new to have ratings yet (US)
- Platforms and languages
- iPhone. English.

Best for logging only, no AI
Hevy
Hevy is for people who see the words AI workout app and think: I already have a program, I just want to write it down. You build routines, log sets, watch the graphs and follow friends who train. The free version has no ads and no cap on logged workouts. Hevy's own comparison page says its Trainer feature follows a rule-based algorithm that does not use AI generation.
Where it is strong
- Free with no ads, unlimited logging and up to 4 saved routines
- Hevy Pro is the cheapest paid plan in this guide: $2.99 a month or $74.99 once for life, per Hevy's site
- Runs on iPhone, iPad, Apple Watch, Android, Wear OS and the web
- Friends can follow and copy each other's workouts
Where it falls short
- A logger first: no AI planning, and its Trainer is rule-based

What "AI" actually does in these apps
Every app on this list uses the same two letters for different jobs. Before you pay for one, work out which job you are buying.
Weights chosen from your history. Fitbod and Gravl read what you lifted, estimate what you can handle now, and set the next session's sets and loads. It is the narrowest job and the easiest to judge: after a month of honest logging, are your numbers going up? It also only works if you log every set. Skip the logging and the app is guessing.
A generated plan. Freeletics, Zing and Aion build a plan from an intake and keep adjusting it. The difference between them is what they adjust from. Freeletics says it uses your feedback, Zing a daily check-in on energy, mood and sleep, and Aion what you logged and what you tell it about your week.
A chat coach. Zing's listing describes an AI coach that suggests goals and schedules workouts. Aion's membership is a chat coach you ask for a swap, a shorter session or another day, and nothing changes until you tap Apply. Chat is the newest layer, so give it the hardest test during a trial: ask it something awkward about your own week and see whether the answer holds up the next day.
A person. Future and Ladder put a human coach behind the plan, and Hevy leaves the plan to you. They belong in an AI list because for plenty of people the missing piece was never the algorithm. It was someone to answer to, or a program they trust and a clean place to log it.
| App | What it reads | What it changes |
|---|---|---|
| Fitbod | Your goal, equipment, logged lifts and your edits | Exercises, sets and weights for each session |
| Gravl | Logged history, Easy or Hard set ratings, your equipment | The next session's reps and weight |
| Future | Your coach's check-ins and your progress | The program, changed by your coach |
| Ladder | Your quiz answers, to place you in a team | The team's weekly program, written by its coach |
| Freeletics | Your goals, level and feedback | Each workout in your plan |
| Zing | Daily energy, mood and sleep check-ins, and the camera | Workout intensity and complexity |
| Aion | Your days, minutes, kit, goal and logged sessions | The next session's step; members can change the week in chat |
| Hevy | What you log | Nothing by AI; its Trainer builds a rule-based program |
How to choose in 2 minutes
Read down the list and stop at the first line that is a clear yes.
- You lift in a gym and mainly want to know what weight to use next: Fitbod, or Gravl if you would rather leave the phone in the locker.
- You want a person to answer to: Future, if $199 a month fits the budget. Ladder, if a coach's team program is enough.
- You train at home with little or no equipment: Freeletics, starting with its free workouts.
- You train alone and worry about your form: Zing, for its camera feedback. A coach watching you in person is still better.
- Your week changes every week, you are chasing a first pull-up or a muscle-up, or you are training for a run or a HYROX race: Aion, whose plan is free.
- You already follow a program and only want to log it: Hevy, free.
Then use the trial properly. Log at least three real sessions before you decide, because any app looks clever on day one. Fitbod and Ladder give you 7 days, Future refunds you within 30 days, and the Freeletics Coach comes with a 14-day money-back guarantee. Aion's plan needs no trial because it does not run out; the annual membership opens with 7 free days.
Questions people ask
What is the best AI workout app in 2026?
There is no single winner, because the apps do different jobs. For gym weights chosen from your log, Fitbod has years of history behind it and Gravl has a standalone watch app. For a plan that follows a week that keeps changing, Aion fits and its plan is free; we make it, so weigh that. If you want a person, Future matches you with a coach for $199 a month.
Is there a free AI workout app?
Aion's plan is free on iPhone, including the progression from your log and one swap per workout; the chat coach is the paid part. Gravl is free to start, with full plans on Premium. Freeletics gives away 34 bodyweight workouts. Hevy is free too, but it is a logger with no AI planning.
Can an AI app replace a personal trainer?
For planning and progression it can cover a lot. None of these apps can watch you lift the way a trainer in the room can, though Zing's camera feedback tries, and none of them can assess pain or an injury. If what you need is someone to hold you to it, Future and Ladder put a person in the loop.
Which AI workout apps work on Android?
Fitbod, Gravl, Future, Freeletics, Zing and Hevy, according to their own sites and terms. Ladder's site says it has no Android app, and Aion is iPhone only.
Do AI workout apps work for home workouts?
Yes. Fitbod's listing says it supports home training with no equipment, Freeletics is built around bodyweight work, and Zing covers home and gym. Aion plans only exercises your kit allows, so a pull-up bar and a pair of dumbbells is a complete setup as far as it is concerned.
How current are these prices?
Every price, rating and platform here was read on October 20, 2026, from each app's US App Store listing and its own site. App Store and web prices can differ and introductory offers vary by account, so the price the app shows you before you pay is the one that counts.
