How it works
No complicated setup. No syncing. Just open the app and start logging.
Get Fortis from the App Store in seconds. Create your account, and 6 exercises are preloaded and ready to go. Your first 14 days are completely free.
Pick an exercise, enter your weight and reps, hit save. Fortis remembers your last session so you always know where to pick up.
After a few sessions your progress charts, streak, muscle balance insights, and PR history start painting a real picture of your training.
Features
No bloat. No subscriptions to features you'll never use. Clean, focused, fast.
Log weight, reps, and notes in seconds. Last-session hints pre-fill so you never start from scratch. Add as many sets as you need.
Best weight, total volume, and estimated 1RM plotted over time for every exercise. See your arc across weeks, months, and years.
Every new personal record is flagged automatically and celebrated in the app. Your PR history for every exercise is always one tap away.
Set a target weight for any exercise. A progress bar tracks how close you are and alerts you the moment you reach it during a session.
Your full training history on a visual calendar. Schedule upcoming sessions, log rest days, and see your streak at a glance.
See exactly how much volume you're putting into each muscle group. Get warned when you're overtraining one area or neglecting another.
Log your bodyweight alongside your training. Charts show your weight trend over time so you can correlate it with strength changes.
Evidence-based set targets per muscle group. Know if you're hitting the right volume each week for hypertrophy or undertraining.
Get nudged when your streak is at risk or it's been too long since your last session. Stay consistent without thinking about it.
Most gym apps just store your data. Fortis actually analyses it. After a few weeks of logging, Insights gives you a clear picture of how you're training — and where you could be doing better.
Consistency beats intensity every time. Fortis's calendar makes your training habit visible — you can see at a glance when you trained, when you rested, and how long your current streak is.
