Log every set. Plan every week. See real progress.
ZyFit records sets with weight, reps and RPE, times your rest automatically and detects personal records, with a celebration the moment you beat one. The AI Coach answers from your own log: review a session, plan the next one, or draft you a full training week you can save in one tap. Thirteen documented calculators and a 72-exercise library are built in.

Log every set in seconds
Weight, reps, done. Your last performance for the same exercise sits right in the set table, and the rest timer starts itself when you finish a set.
Plan routines and programs
Build routines, schedule them across the week, set target reps, RPE and rest for each exercise, then start a workout straight from the plan.
See the numbers move
Estimated one rep max trends, weekly volume and muscle distribution, computed from the sets you actually completed and linked back to each workout.
Records and achievements
Personal records for every lift, plus milestones unlocked by your own training. No invented badges, only progress your log proves.
Nutrition and hydration
Log calories, macros and water against the targets your calculators produce, and watch the week line up next to your training load.
Timers that behave
The rest timer counts down in the tab title and keeps running in the background. Warmup, working and drop sets are recorded separately.
