Feature
Log every set while you train
Follow today’s plan, reuse a routine or build a workout on the spot. Fitaio shows your last numbers, times your rest and keeps the session moving.
Start from your plan
The Train tab opens the day your active plan calls for, exercises and target sets already in place.
Previous performance
Every exercise shows what you did last time, so you know whether to add load.
Rest timer
Starts when you complete a set, with your own default length from Settings.
Plate calculator
Enter the target load and see the plates per side for your bar.
Routines and history
Save a day as a routine to reuse, and find every past session in your history with volume and duration.
How it works
Pick a workout
Today’s plan day, a saved routine or an empty session.
Log as you go
Weight, reps and RPE per set. Warm-ups are marked so they do not count toward records.
Finish and review
The summary shows volume, sets and any new personal record.
Common questions
Can I log in kilograms or pounds?
Yes. Switch units in Settings. The developer API always uses kilograms.
Does the tracker work on the web?
Yes. The web app at fitaio.app/app has the same tracker as the phone apps.
