GYM LOG & WORKOUT TRACKER
• Clean, notebook-style gym log built for speed

• Tag sets as warm-up, normal, drop set or failure
• Automatic rest timer, plate calculator and one rep max calculator
• Personal records for every exercise

HANDS-FREE TRAINING
• Auto-advance: after you log a set, Fitns moves straight to the next one
• Voice cues: when your rest timer ends, Fitns reads out your next weight and reps, so you can keep your eyes off the phone between sets

SMART MUSCLE MAP
• A 3D muscle map shows the stimulus each muscle gets, from chest and back to quads, glutes and calves
• Every exercise is split across the muscles it trains, and every set is weighted by effort (RIR) and set type
• Weekly stimulus per muscle lands in a zone: low, maintaining, growth, focus or recovery risk
• Zones follow the volume landmarks used in hypertrophy training (MEV, MAV, MRV) and adapt to your level, from beginner to elite
• Compare each muscle with the previous period and check its training frequency, recovery spacing and a confidence score
• Stimulus is an estimate based on the sets you log

PROGRESS TRACKING
• Track strength training progress and progressive overload with one rep max, volume, reps and duration charts
• Stats for the week, month, six months, year or lifetime, each compared with the period before
• Averages per workout: volume, duration, intensity, exercises, sets and reps

EXERCISES & ROUTINES
• 400+ exercises with demonstrations, filtered by muscle or equipment
• Create your own exercises and routines
• Plan push pull legs, upper/lower, full body or any split you like
• Train at the gym or at home: log barbell, dumbbell, machine and band exercises
