Your body measurements. Always to hand. UltraSize helps you capture your body measurements, store them securely and compare them over time. Whether you are training for bodybuilding, following a diet, or simply want your measurements with you when you shop โ UltraSize keeps you on top of your progress. Record the measurements that matter: height, shoulders, chest, waist, hips, neck, arm length, inseam, thigh, calf, biceps and forearm. Every value is time-stamped so you can see exactly how things have changed and compare new readings to any earlier entry. Your data stays with you UltraSize works without an account, without tracking and without any cloud AI. Your measurements stay on your device. If you choose, you can turn on the optional iCloud sync to keep your data in step across your own Apple devices โ privately, in your own iCloud. On-device automatic measurement With camera mode, UltraSize can estimate your body dimensions right on the device. The app uses Apple's Vision framework to detect your pose and compute approximate measurements locally โ no upload, no server. Important: camera measurement is a convenient estimate, not a replacement for a tape measure. Lighting, clothing and posture can all affect the result. For tailor-grade accuracy you should still measure by hand. For following your progress across weeks and months, though, the automatic measurement is fast and practical. Features โข Twelve essential body measurements you can capture and edit โข Multiple profiles โข Time-stamped history โข Compare values and trace every change โข On-device automatic camera measurement โข Switch between centimetres and inches at any time โข Optional iCloud sync โข No account, no tracking, no cloud AI UltraSize is for anyone who wants to document their measurements cleanly, follow changes in their body, or have the numbers to hand when shopping.
Pixel Workout

Pixel Workout is a free, offline workout tracker for iPhone that turns every training session into a pixel on a GitHub-style contribution grid. Log your sets, watch your year fill with color, and build a streak you can actually keep. THE YEAR GRID Every active day earns a pixel โ colored by what you trained (push, pull, legs, cardio, core) and brighter the harder you worked. Your whole year of training on one screen. When it looks good, share it: one tap renders your grid as an image for the group chat. WEEKLY STREAKS THAT SURVIVE REST DAYS Pick a weekly goal you can keep โ 3, 4, or 5 days. Rest days never break your streak; only a missed week does. Milestones at 2, 4, 8, 12, 26, and 52 weeks keep the long game interesting. FAST, FLEXIBLE LOGGING Sets and weight, timed holds, distance cardio, or a hundred bodyweight squats a day โ log it how you train it. Steppers prefill from your last session, an in-app numpad keeps you off the keyboard, and a rest timer starts itself after weighted sets. TRAINING PROGRAMS WITH AUTO-PROGRESSION Eight ready-made plans โ Full Body A/B, Push Pull Legs, Upper/Lower, classic 5x5 strength, bodyweight-only, dumbbell-only โ or build your own in the editor. Targets progress automatically from what you actually lifted last time: hit the top of the range and the plan adds weight; fall short and it holds. PERSONAL RECORDS, DETECTED Heaviest set, estimated 1RM, best-day totals, longest hold, fastest pace - records fire the moment you log them, for every training style, with a gold flash to match. PROGRESS YOU CAN SEE Every exercise gets its own chart โ topduration, or distance โ drawn in chunkypixel lines that make the trend obvious at a glance, plus a per-exercise activity grid so consistency shows up lift by lift. SUPPLEMENT CHECKS One-tap daily checks for creatine and friends, tracked separately so rest days never touch your training grid. MADE FOR HOW YOU TRAIN Lifters chasing a 5x5, runners logging miles, calisthenics athletes counting daily push-ups, plank holders and stretchers โ every training style erecords on equal terms. YOUR DATA IS YOURS No account. No cloud copy of your training. Workouts live on your iPhone with one-tap JSON backup, and the whole app works fully offline โ log in ng. The app collects only anonymoususage statistics to help improve it; your training data is never uploaded. Free, with no ads and no subscriptions. Every workout is a pixel. Start filling

Verdict
The clearest difference is update cadence: UltraSize at every 5 days against Pixel Workout's fortnightly. Pixel Workout's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
