Both are serious workout loggers. The difference is whether you want a logger on its own, or your lifts beside your body composition, protocols and lab results.
We make Hemingway Performance, so read this with that in mind. Everything below about Strong comes from their US App Store listing and their website, checked November 2026. Apps change; check theirs before deciding.
Strong is a long-established workout tracker on iPhone and Android with a fully featured Apple Watch app that logs workouts with or without your phone. It has supersets, RPE, a warm-up calculator, custom timers, charts and CSV export, and the free version saves unlimited workouts (custom routines are capped at three). If you want logging and nothing else, it is hard to fault.
We log workouts too — programs, supersets, rest timer, RPE, PRs, estimated 1RM and Beginner-to-Elite strength standards — and on Performance an engine reads your last session and sets the next one's weights. What we add is everything around the training: body composition from a smart scale or DEXA, protocol tracking with reminders, and lab PDFs that are read and trended for you, all on one timeline.

If you've been logging in Strong, you don't start from zero. Export your data from Strong as a CSV, then in Hemingway go to Profile → Import workout history. Strong's file doesn't say whether it's in pounds or kilograms, so we ask. Your sessions land in your history and personal bests; exercises we recognise are matched to our library, and anything else is kept under your own name. It works best on the web dashboard.
Free to use, no card needed.
