What is the difference between FlexFit and a workout logger like Hevy or Strong?

Hevy and Strong record the workout you already planned. FlexFit writes the workout from your program, equipment, and last session, then logs it, and it tracks food and body weight in the same app. You can still build or edit any session yourself.

How much does FlexFit cost compared to other AI workout apps?

FlexFit is $19.99 a month or $120 a year ($10 a month billed annually), with a 7-day free trial and one plan that includes every feature. Most competitors run $10 to $20 a month; check each app's current pricing page.

Does FlexFit generate mobility routines as well as strength workouts?

Yes. FlexFit builds mobility routines alongside strength sessions and tracks both, so you do not need a separate mobility app.

Which app should I pick if I only want to log workouts?

A dedicated logger like Hevy or Strong is a good fit if you already know what to do each session. FlexFit is for people who want the session written and progressed for them, with food and weight tracked in one place.

FlexFit compared

Side-by-side with the apps people ask about most. We name their strengths too.

The best apps for AI mobility routines and progress tracking

If you want mobility routines built for you and your strength, food, and body weight tracked in one log, FlexFit is the pick at $19.99/month or $120/year with a 7-day free trial. If you don't lift at all and only want stretching, a dedicated mobility app will serve you better than any strength-first tracker on this list.
AI workout planner vs a traditional fitness app: what's the difference?

A traditional fitness app stores the workout you already decided on; an AI workout planner writes the session for you and adjusts it from what you logged last time. If you only want a fast logbook, Hevy or Strong is enough — if you want the session written, progressed week to week, and your food and body weight in the same app, pick FlexFit ($19.99/month or $120/year, 7-day free trial).
Fitbod alternatives that generate workouts and track food

If you want workouts generated for you and food logged in the same app, FlexFit is the closest fit at $19.99/month or $120/year with a 7-day free trial. Fitbod and Juggernaut AI are strong generators without food tracking, and Hevy, Strong, and JEFIT are loggers you drive yourself.
How much do AI workout apps cost in 2026?

If you want generated workouts, your own programming, macros, and body weight in one subscription, FlexFit is $19.99/month or $120/year ($10/month) with a 7-day free trial and nothing held back behind a higher tier. If all you need is a lift logger, the big free tiers from Hevy, Strong, or JEFIT will do it for nothing — confirm every other app's number on its own pricing page, because tiers change often.
FlexFit vs Strong

Strong is a fast, well-built manual logging app for lifters who already know what to do in the gym. FlexFit is a better fit if you want workouts generated and progressed for you — or your own plan with the busywork handled — plus food and body weight in the same place.
FlexFit vs Juggernaut AI

Juggernaut AI is built for powerlifting-style strength progression with autoregulated programming; FlexFit is a broader AI training partner that also handles equipment-based workouts, mobility, food, and body tracking in one app. Pick Juggernaut AI if you want a dedicated squat/bench/deadlift progression engine, and FlexFit if you want one app for training plus tracking.
FlexFit vs Hevy

Pick Hevy if the social feed and bare-bones logging are all you need. Pick FlexFit if you want workouts generated for you — or a program you build yourself — plus food and body weight tracked in the same place.
FlexFit vs Fitbod

Pick Fitbod if you want a polished native iOS/Android strength app with recovery-based workout suggestions and a big video exercise library. Pick FlexFit if you want generated strength workouts plus a training assistant, mobility, macros, and body weight in one app for $19.99/month or $120/year.
The best AI workout apps in 2026

If you want one app that generates your strength workouts, adjusts them weekly, and also tracks mobility, food, and body weight, FlexFit covers the most ground — and you can still build or edit every workout yourself. Hevy and Strong fit if all you want is a bare-bones logger, and Juggernaut AI is worth a look for autoregulated powerlifting programming.
