Volume is a workout logger with one job: show you a single number for how much work you did, and make beating it next time feel good. Log your reps and weight. Volume multiplies them out across every set and gives you one score for the session. Next time you do that workout, that score is already sitting there as your target. HOW IT WORKS • Log sets in seconds — big buttons, a full-size number pad, one-handed between sets • Every workout gets one volume score: reps × weight, added up • Start each session with last time's score as the target to beat • Pass it and you'll know about it BUILT AROUND YOUR WORKOUTS, NOT OURS You name your own workouts — Push, Leg Day, Tuesday, whatever you call them. Volume always compares like for like, so your Pull day is measured against your last Pull day and never against yesterday's Legs. There's no split to pick and no muscle-group taxonomy to fight. TWO STREAKS • Records in a row — every workout you beat adds one • Weekly streak — set your own target of 1 to 7 days a week WHAT ELSE • 50+ exercises built in, or add your own • Warm-up sets are logged but don't inflate your score • Personal bests and PR counts for every workout • Calendar of everything you've logged, with backdating for sessions you forgot • Charts per workout, over 3 months to all time • Pounds or kilograms, switch anytime • Syncs across your devices through your own iCloud — no account, no sign-up • Full dark mode WHAT IT DOESN'T DO No coaching. No AI. No workout plans. No rest timers. No social feed. No login. Volume doesn't tell you what to do — it keeps the log and shows you the number. FREE Volume is free. No ads, no in-app purchases, and no data collected.

Verdict
The clearest difference is in-app purchases: Volume at none against Woomi's 3. Woomi's advantage is update cadence (daily vs every 3 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
