weyt.ai vs Hevy
Hevy is a social workout logger with a big library and native apps. weyt.ai is a strength coach that shows where you stand for your age. 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 Hevy is
Hevy, as of 2026, is a widely used workout tracker built around set-by-set logging, saved routines, a large exercise library with demonstrations, progress charts, and a social layer where you follow friends and like or comment on their workouts. It ships native iOS and Android apps, a web app and watch apps, and runs a free tier alongside a paid Pro subscription.

“varies” means the answer depends on tier, platform or release and we would rather not guess.
Who should pick which
- You want a native app from the App Store or Play Store today, with watch logging.
- A social feed of friends' workouts is part of why you train.
- You want the largest possible exercise library with demonstrations.
- You already log in Hevy and like it; there is no reason to move your history.
- You want your strength ranked against real population norms, by age and sex, and a number that moves.
- You want a coach that reads your actual sets and answers with your numbers, not generic tips.
- You want progression written into your plan for you after each session.
- You would rather install a web app than wait for a store listing, and you want it free on the web 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 Hevy; it is a different bet about what a training app is for.
Questions
Is weyt.ai a replacement for Hevy?
For logging, yes: weyt.ai logs sets, runs a rest timer and keeps history. For a social feed of friends' workouts and native store apps, no; Hevy has those and weyt.ai does not. weyt.ai adds what Hevy does not: a Weyt Age ranked against population norms, muscle groups hit and sessions done counted by fixed rules, and a coach that has read every set you logged.
Does weyt.ai import workouts from Hevy?
Not today. There is no Hevy importer; the coach builds your first workout from three answers, and you can build your own, design one with the coach, or read one from a photo of your old log. Your number needs only one chest press or one squat to appear.
What does weyt.ai cost compared with Hevy?
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. Hevy runs a free tier plus a paid Pro subscription; check their site for current prices.
