weyt.ai vs Fitbod
Fitbod generates each workout for you and adapts it to your recovery and equipment. weyt.ai gives you a plan you own and a coach that tells you whether it is working. Here is where they overlap, where they do not, and who should pick which.
What weyt.ai is
weyt.ai is a strength training app with a coach, free on the web while its iPhone app is being prepared. Three answers at sign-up (what you train for, the standards and age to measure you against, what you train with) and the coach builds your first workout. You log a workout in two taps or lift through a live set-by-set session with a rest clock and the plates to load drawn for you, and a workout can be read from a photo or a screenshot. Every set feeds two plain counts, the muscle groups you have hit and the sessions you have done, kept by fixed rules with no AI. Your bench press and squat set a percentile and a Weyt Age against two ladders: the general population (Cooper Institute and ACSM bench-press norms) and lifters who track (Strength Level standards); one bench set at weyt.ai/weyt-age gives a first number in thirty seconds without an account. The coach is one tap away on every screen, has read every set you logged, and after your workouts writes one short read with one change to make. Your plan's targets move after each session by double progression, and Shared lets you add a popular workout with its weights set from your own lifts.
What Fitbod is
Fitbod, as of 2026, is a workout app built around algorithm-generated sessions: you tell it your equipment, your goal and how you feel, and it writes the day's workout, adjusting exercise selection and loads to your recent training and the muscle groups it considers recovered. It ships native iOS and Android apps with an Apple Watch app, an exercise library with demonstrations, and integrations with the phone's health platforms. It is a paid subscription after a short free trial.

Feature by feature
| Feature | weyt.ai | Fitbod |
|---|---|---|
| Core idea | Where you stand against real norms (a percentile and a Weyt Age), a plan you own and a coach that reads it | A generator: each workout written for you from your recovery, equipment and goal |
| Who writes the workout | You, the coach's first workout from three answers at sign-up, or Design with coach; the plan then adapts by double progression | The algorithm, every session |
| Workout logging | Two-tap log, log-with-changes, or a live set-by-set session with a rest clock and the plates drawn | Set-by-set logging with a rest timer |
| Muscle groups and sessions | Muscle groups hit and sessions done, counted by fixed rules, no AI in the numbers | varies |
| Strength age vs population norms | Weyt Age on two ladders: general population (Cooper/ACSM) and lifters who track (Strength Level) | no |
| Per-lift strength standings | Percentile and level per norm lift by sex, bodyweight and age | varies |
| AI coach | A short read after your workouts with one change to make, plus a chat coach that has read every set you logged | no chat coach; the adaptation is the product |
| Adaptive progression | Double progression writes next-session targets into your plan after every workout | Loads and selection adapt per generated workout |
| Muscle balance | One circle per muscle group over 30 days, each set against what it needs | Recovery-based muscle map drives selection |
| Exercise library | 391 catalog exercises plus custom ones; any spelling counts as the same lift | Large library with demonstrations |
| Community | Shared: add a popular workout and its weights are set from your own lifts, or share yours as a public link; no feed of friends' sessions | varies |
| Platforms | Web app that installs on your phone from the browser; an iPhone app is being prepared, not in the App Store yet | Native iOS and Android apps, Apple Watch app |
| A workout from a photo | A whiteboard, a printout or another app's screen becomes a workout you check and save | varies |
| Wearables | A run read from a running app's screenshot: distance, time and heart rate | Watch app and health-platform integrations |
| Price | In the iPhone app, 7 days free, then $9.99 a month; the web app is free while the iPhone app is being prepared | Subscription after a free trial (check their site) |
| Ads and data | No ads, no selling of data; delete your account and everything with it from Settings | varies |
“varies” means the answer depends on tier, platform or release and we would rather not guess.
Who should pick which
- You want to walk into the gym and be told exactly what to do today, with no plan of your own to maintain.
- You want a native app from the App Store or Play Store with watch logging today.
- You train with whatever equipment is around and want the workout rewritten to it each time.
- You already pay for Fitbod and like the generated sessions.
- You want to know how strong you actually are: a Weyt Age against real population norms, by age and sex, from one bench set.
- You would rather own a plan that adapts by clear rules than be handed a new workout you did not choose.
- You want every session set beside the last one, and a coach read that commits to one change.
- You want it free on the web today, with no ads.
Plenty of lifters run both: a logger they already like at the rack, and weyt.ai for where they stand and the coach. Nothing here is a knock on Fitbod; it is a different bet about what a training app is for.
Questions
Does weyt.ai generate workouts like Fitbod?
Partly. The coach builds your first workout at sign-up from three answers, and Design with coach drafts a complete workout from your history when you ask. After that the plan is yours: it adapts by double progression after every session rather than being regenerated each day. Fitbod regenerates the workout every session from your recovery and equipment.
Which one tells me if I am getting stronger?
weyt.ai is built around that question: a Weyt Age ranked against population norms, a strength card that reads each lift's best lift estimate (an estimated one-rep max) over twelve weeks, PRs called out after each session, and a coach read after your workouts with one change to make. Fitbod tracks your history and adapts loads, but it does not rank you against population norms or publish a strength age.
What does weyt.ai cost compared with Fitbod?
In the iPhone app, weyt.ai is 7 days free, then $9.99 a month, monthly only, through Apple. There is no free version. If your subscription ends, your account and everything you logged are kept, and training is locked until you renew. The web app is free while the iPhone app is being prepared. Fitbod is a paid subscription after a short free trial; check their site for current prices.
