Best Gym Workout App for Planning and Tracking
Fitonist is a gym workout app for people who want planning, logging, exercise videos, and progress analytics in one place. It can generate workouts, let you build custom routines, track every set and rep, and work from iPhone, Android, or Apple Watch.
What a gym workout app should do well
A useful gym app needs to survive real workouts: equipment is busy, time is limited, and your plan may need changes between sets. Fitonist is built around that practical gym flow.
Plan workouts before you start

Who Fitonist is best for
| Gym user | Why Fitonist fits |

Not just a workout logger, not just a fixed program
Many gym apps make you choose between rigid programs and empty logging. Fitonist sits between those two modes: it can create a workout for you, but it also lets you edit the details when you know what you want.
- ✓ Use AI when you want a quick structured session.
- ✓ Use custom workouts when you want total control.
- ✓ Use exercise videos when you need form guidance.
- ✓ Use analytics when you want to understand whether training is moving forward.
