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 a clean logger. The UI is tidy, the exercise library is large, logging is fast, and there's a social feed for following other lifters and sharing workouts. Checkfit logs your sets just as cleanly, from the same kind of large exercise database — and then keeps going: it writes the program, picks the weights, and manages the progression Hevy leaves to you.
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.
An optional coach connection comes with it too, if you want a person looking at the same data. Hevy logs your sets; Checkfit decides them.
What $17/mo actually buys
The logging is the easy part — Hevy does it well and so does Checkfit. The expensive part is the programming: the block that knows your current strength, the load for each set, the volume that's enough without being too much, and the deload before you dig a hole.
Checkfit's $17/mo is that engine. Six-week hypertrophy mesocycles calibrated to two lifts you already know, per-set weights computed from RIR-based math, managed volume, scheduled deloads, and an optional coach connection — with clean logging and a full exercise database underneath. You're not paying for a place to write numbers down; you're paying for the numbers.

The verdict
Checkfit logs as cleanly as Hevy and then does the work a logger can't: it writes the six-week mesocycle, picks every weight, autoregulates from your reps in reserve, manages volume and schedules deloads, and includes an optional coach connection — $17/mo, with no program or coach to buy on the side. Equal where it counts to Hevy, ahead everywhere else. Get Checkfit.
