Checkfit vs Strong.
Strong records your workout. Checkfit decides it. Strong is a logger that assumes you bring the program; Checkfit is the program, written for you and built to grow muscle.
What Strong does well
Strong is a clean lifting logger with a fast interface and a broad exercise database. Checkfit logs every set just as cleanly — the difference is what happens around the logging. Strong records what you did; Checkfit also decides what you should do next. Anything Strong does inside a workout, Checkfit does too, and then keeps going.
Why lifters choose Checkfit
Strong assumes the hard part is already solved. It never picks a weight, calls a deload, or tells you when to push. If the program you're logging stopped working, a logger just keeps a tidy record of you not progressing.
Checkfit writes the program and runs it. It calibrates a six-week hypertrophy mesocycle to your current strength, picks the weight for every set, manages your volume, schedules deloads, and adjusts the next session from the reps in reserve you reported on the last one. You don't decide what to lift, how heavy, or when to back off — the app does, using the same hypertrophy science a good coach would.
And if you want a person involved, an optional coach connection is part of the app — someone who can see your training and adjust the plan with you. Strong tracks your sets; Checkfit decides them.
What $17/mo actually buys
With a logger, the app is the cheap part. The program is what costs you — a template you buy, a spreadsheet you maintain, or a coach on retainer. Strong keeps a tidy record of whichever of those you're running.
Checkfit's $17/mo is the program itself: the six-week mesocycle calibrated to your lifts, the weight for every set, the volume management, the scheduled deloads, the RIR-based progression, and an optional coach connection — with logging as clean as Strong's underneath it. One subscription, no program to source on the side.

The verdict
Strong is a logger, and Checkfit logs just as cleanly — so on the thing Strong does, they're even. Everywhere else, Checkfit does more: it writes the six-week mesocycle, picks every weight from your reps in reserve, manages volume, schedules deloads, and includes an optional coach connection — all for $17/mo instead of a logger plus a program you buy elsewhere. Equal where it counts to Strong, ahead everywhere else. Get Checkfit.
