Checkfit vs Hevy.
Hevy and Checkfit both live on iOS and both serve lifters. They take very different approaches, and the better one depends on what you want the app to do for you.
What Hevy does well
Hevy is genuinely good. The UI is one of the cleanest in the category, the core app is free, and the social and community features make it the closest thing strength training has to a Strava. The exercise library is large, the logging is fast, and you can follow other lifters and share workouts. For someone who already trains and wants a beautiful place to track it, Hevy is hard to beat.
Where Checkfit is different
Hevy logs the work. Checkfit decides the work. Checkfit's job is to pick your exercises, calculate your weights, run the progression, and call deloads. The app is built around an algorithm that reads what you did last session and writes the next one. Hevy hands you a blank page; Checkfit hands you a calibrated session. If you want the community and the freedom to design your own training, Hevy fits. If you want the decisions made for you, Checkfit fits.

Which one is for you
If you already have a program and you want a great place to record it, the other app is a fine choice — possibly better. If you don't have a program, or the program you have stopped working, that's the gap Checkfit is built to fill.
