Checkfit vs Hevy.
Hevy records your workout. Checkfit decides it. Hevy is a logger — you bring the program; Checkfit is the program, written for you and tuned to build muscle.
What Hevy does well
Hevy is genuinely good. The UI is one of the cleanest in the category, the core app is free, and with 14M+ users and 4.9-star ratings it has the closest thing strength training has to a social network. The exercise library is large, logging is fast, and you can follow other lifters and share workouts. For someone who already has a plan and wants a beautiful place to track it, Hevy is hard to beat.
Why lifters choose Checkfit
Hevy hands you a blank page. That's the whole catch — it never tells you what to lift, how heavy, or when to back off. If you don't already have a program that works, a logger just records you spinning your wheels.
Checkfit writes the program and runs it. It calibrates a six-week hypertrophy mesocycle from two lifts you know, picks every weight, manages your volume, schedules deloads, and adapts each session to the reps in reserve you logged last time. This is hypertrophy science — the same method serious coaches use — automated end to end so you just train.
It also covers the part that actually builds the muscle: daily calorie and protein targets are built in, and an optional coach connection comes with it. Hevy logs your sets; Checkfit handles the programming and the nutrition that turns those sets into size.
Nutrition the others don't have
Hevy is a great place to track a workout and a great place to compare workouts with friends. What it can't do is help you eat for the result. There's no calorie target, no protein goal, no food log — and all the volume in the world won't build size if you're not eating for it. Checkfit puts that inside the same app: a daily calorie and protein number, and a food logger to hit it. Search a food, add it, and watch the running total close in on your target for the day.
One subscription covers the training and the eating — no separate macro app bolted on the side. See how nutrition works.

The verdict
If all you want is a free notebook for a program you already trust, Hevy is fine — better, even. But a notebook doesn't make you grow. Checkfit writes the program, picks every weight, and logs your food against a calorie and protein target — programming plus nutrition in one $17/mo subscription. If you want the work done instead of just recorded, get Checkfit.
