weyt.ai vs Hevy
Hevy is a social workout logger with a big library and native apps. weyt.ai is a strength scoreboard with an AI coach. Here is where they overlap, where they do not, and who should pick which.
What weyt.ai is
weyt.ai is a free (in beta), web-based strength training app with a scoreboard. You log a workout in a few taps or lift through a guided set-by-set session with a rest timer, and every set feeds three deterministic scores (Gains, Balance, Routine) that roll into one Weyt Score. Your best bench press and squat set a Weyt Age against two ladders: the general population (Cooper Institute and ACSM bench-press norms) and lifters who track (Strength Level standards). A floating coach button opens an AI coach (Anthropic Claude) that has read your whole history and can log, edit or design a workout mid-conversation. Progression is written into your plan after each session by double progression. It installs on a phone as a web app (PWA); there is no app store listing yet.
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.

Feature by feature
| Feature | weyt.ai | Hevy |
|---|---|---|
| Core idea | A scoreboard: one Weyt Score that moves, a Weyt Age ranked against real norms | A social logger: record workouts, follow routines, share with friends |
| Workout logging | Two-tap log, log-with-changes, or a guided set-by-set session with rest timer | Set-by-set logging with rest timer and routines |
| Training score | Weyt Score = mean of Gains, Balance, Routine (each 0 to 100), deterministic, no AI in scoring | no |
| 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 | Streaming chat coach grounded in your full history; can log, edit plans, design workouts | varies |
| Adaptive progression | Double progression writes next-session targets into your plan after every workout | varies |
| Swap-in suggestions when a lift stalls | Deterministic: the recap and the weekly review name a same-muscle alternative; you decide | varies |
| Exercise library | 212 catalog exercises plus custom ones; any spelling resolves to one movement | Large library with demonstrations; custom exercises |
| Community | Your crew: publish, like, add and do shared workouts under an @handle; no feed of friends' sessions | Social feed: follow friends, like and comment on workouts, share routines |
| Platforms | Web app, installs as a PWA on iOS and Android; no app store listing yet | Native iOS and Android apps, web app, watch apps |
| Wearables | Optional watch screenshot import of duration, heart rate and calories | Watch apps for logging |
| Price | Free in beta, every feature, no credit card; a Pro tier is planned | Free tier plus Pro subscription (check their site) |
| Ads and data | No ads, no selling of data, hard delete from Settings | varies |
| Units | lb or kg, display only; everything stored in kg | lb or kg |
“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 scoreboard 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 free in beta with no ads.
Plenty of lifters run both: a logger they already like for the gym floor, and weyt.ai for the scoreboard 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 deterministic Weyt Score, a Weyt Age ranked against population norms, and an AI coach grounded in your data.
Does weyt.ai import workouts from Hevy?
Not today. There is no Hevy importer; you start with four starter workouts, build your own, or have the AI designer write one from your equipment and goals. Your Weyt Age needs only a bench press and a squat set to appear.
What does weyt.ai cost compared with Hevy?
weyt.ai is free while in beta with every feature included and no credit card. A Pro tier is planned and pricing may change before launch. Hevy runs a free tier plus a paid Pro subscription; check their site for current prices.
