weyt.ai vs Strong
Strong is a fast, minimalist workout logger with a well-regarded Apple Watch app. 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.

“varies” means the answer depends on tier, platform or release and we would rather not guess.
Who should pick which
- You log from an Apple Watch and want a native app from the store today.
- You want the fastest possible set entry with nothing else on screen.
- You prefer a tool you pay for once (where still offered) over a subscription.
- You already have years of history in Strong and only need a logger.
- 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, and a suggested swap-in when a lift stalls.
- 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 Strong; it is a different bet about what a training app is for.
Questions
Is weyt.ai a replacement for Strong?
For logging, yes: weyt.ai logs sets, runs a rest timer and keeps history. For Apple Watch logging and native store apps, no; Strong has those and weyt.ai does not. weyt.ai adds what Strong 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 Strong?
Not today. There is no Strong 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 Strong?
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. Strong has a free tier and a paid Pro tier that has been sold both as a one-time purchase and as a subscription; check their site for current prices.
