Fitbod
Price: $15.99 a month or $95.99 a year, 7-day free trial, no free tier.
Fitbod builds workouts based on the equipment you tell it you have and rotates exercises using a muscle-recovery model, so it tries to avoid hitting the same muscle group two days in a row. It's a solid choice if you like a fresh workout generated each session with minimal setup.
Verdict: Good for varied, equipment-aware workouts, but it doesn't track food or body weight, so you'll need a second app for that.
Juggernaut AI
Price: $34.99 a month or $349.99 a year, 2-week free trial, no free tier.
Juggernaut AI comes from a well-known strength-sports coaching background and focuses on autoregulated programming — it adjusts your working weights based on how your sets go. It leans toward powerlifting and strength-focused lifters rather than general fitness.
Verdict: Strong pick if you specifically want autoregulated strength programming and don't need nutrition or mobility tracking in the same place.
Hevy
Price: Free, ad-free logging. Hevy Pro is $2.99 a month, $23.99 a year, or $74.99 for life.
Hevy is primarily a workout logging app with a clean interface and a genuinely social feed — you can follow friends, see their workouts, and share your own. It has routine templates, but it doesn't generate a program for you; you decide what to do each session.
Verdict: Great if logging speed and social motivation matter more to you than having an AI decide your workout.
Strong
Price: Free forever for logging. Strong PRO is $4.99 a month, $29.99 a year, or $99.99 for life.
Strong is another established logging app, similar in spirit to Hevy: fast set entry, custom routines, and progress charts. It's less social than Hevy but has a long track record and a loyal user base.
Verdict: A dependable choice if you already know your program and just want a clean way to record it.
JEFIT
Price: Free Basic tier. Elite is $12.99 a month or $69.99 a year.
JEFIT pairs a large exercise library (1,400+ movements with demos) with prebuilt plans and a solid logger. Elite adds designed programs, analytics, video demos, and removes ads. The plans are templates you follow rather than sessions generated around what you did last time.
Verdict: A good value if you want a big library and ready-made programs, and you're fine driving progression yourself.
Ray
Price: From $19.99 a month after a 7-day free trial; discounted 3- and 12-month plans, prices not published. iOS only.
Ray is a voice-coached trainer: it plans your week, talks you through each session, and counts reps with the phone camera. It's built around guided sessions rather than a program you edit.
Verdict: Worth a look if you want a coach in your ear during the workout. Less so if you want to build or edit your own programming, or you're on Android.
Forge Trainer
Price: $19.99 a month or $59.99 a year (about $5 a month), with a $6.99 weekly option and a 7-day free trial. iOS and Android.
Forge builds custom workouts around your goals, schedule, and injuries, and adds an AI coaching chat. The annual price is the lowest of the generators here.
Verdict: The budget pick among generators if you pay yearly. It doesn't bundle food or body tracking.
FlexFit
Price: $19.99 a month or $120 a year ($10 a month), 7-day free trial, one plan with every feature.
FlexFit generates your strength workouts from your equipment, schedule, and how your last session felt, and adjusts week to week automatically. You can also build your own programs and edit any generated session — swap exercises, add or drop sets, or run your own split. The same subscription also covers mobility routines, food and macro logging (by text or photo), and body weight tracking, so you're not stitching together separate apps.
Verdict: Best if you want the programming decisions handled — or just a head start you can edit — with training, mobility, and nutrition in one place.
Which one for you
Pick Fitbod or Juggernaut AI if you want AI-driven programming but don't need food or body tracking bundled in. Pick Hevy or Strong if all you want is a fast logger, with Hevy adding social features Strong doesn't have — though FlexFit will happily run a program you build yourself, too. Pick FlexFit if you want the workout-generation piece of Fitbod or Juggernaut AI plus food, weight, and mobility tracking in the same app, without hitting a paywall on any of it.
