Comparison
FitFo vs Strong
Strong is the better pick if you already know your program and want the leanest possible logger. FitFo is closer if you want the logging plus a way in: automatic rest windows sized per exercise, next-set suggestions from your last session, and import from a video you saved. Both apps log sets and reps competently, and both have a free tier — the decision comes down to where your workouts come from.

Should you use FitFo or Strong?
Use Strong if you are lifters who want the fastest possible set entry and nothing else. Use FitFo if you want free unlimited set logging with rest timers that size themselves per exercise, next-set suggestions from your last session, and the ability to turn a TikTok or Instagram Reel into an editable workout in about 30 seconds.
What is Strong?
Strong is a long-running workout tracker focused on speed of entry. It strips the interface down to logging sets against a routine, with a rest timer, plate calculator, and one-rep-max estimates. It is frequently cited as the fastest app for getting a set recorded and getting back to lifting.
What Strong does well
- Fastest set-entry interface among mainstream loggers
- Deliberately minimal — no feed, no gamification, no noise
- Long-standing Apple Watch support and a loyal iOS user base
- Solid plate calculator and one-rep-max estimation
Where it falls short
- The free tier limits how many custom routines you can save — check current limits in-app
- Minimalism cuts both ways: little help deciding what to train
- No path from a workout you saw online into the app except retyping it

Which should you pick: FitFo or Strong?
Pick Strong for its core strength — fastest set-entry interface among mainstream loggers. Pick FitFo if most of the workouts you actually want to run are ones you saved from social video, and you want them logged with automatic rest timing and progression tracking rather than retyped by hand.
Neither choice is permanent, and both apps are free to try. The one real cost of switching later is your training history, so whichever you pick, check that you can export it before you build a year of data inside it.
