See what’s actually changing in your physique. GainFrame turns progress photos into body-fat estimates, muscle-group insights, side-by-side comparisons, and an AI Coach grounded in your real check-ins—not generic fitness advice. FROM PHOTO TO PROOF • Compare any two check-ins side by side • See body-fat, weight, and physique-score changes together • Open an AI Deep Dive that explains what changed—and why • Review 12 muscle groups across front and back poses AN AI COACH THAT KNOWS YOUR DATA Ask Coach about your latest check-in, weight trend, training, sleep, or recovery. Responses use the data you choose to connect, so the guidance reflects your actual progress instead of a generic template. SEE MORE THAN THE SCALE • Body-fat estimates from progress photos • Physique scoring and muscle-group breakdowns • Precision estimates from multiple poses • BMI and FFMI trends • Future You physique projections • Weekly and monthly progress chapters BUILT FOR CONSISTENT CHECK-INS • Guided pose templates and photo alignment • Import existing photos from your camera roll • Organize every check-in in a visual timeline • Track streaks, milestones, and weight trajectory • Create shareable before-and-after cards CONNECTED TO YOUR ROUTINE Connect Apple Health, Hevy, and Strava to bring weight, workouts, cardio, sleep, HRV, and recovery into the same progress story. PRIVATE BY DESIGN Your progress-photo library is stored on your device, and no account is required to start tracking. When you choose an AI feature, the selected photos are securely processed for analysis and are not stored on GainFrame servers. HOW IT WORKS 1. Capture a check-in or import photos you already have 2. Get your visual progress read and body-composition estimates 3. Compare over time and ask Coach what to focus on next Start your next check-in and turn the work you’re already doing into progress you can see. IMPORTANT GainFrame is a fitness tracking tool, not a medical device. AI-generated estimates—including body-fat percentage, BMI, FFMI, muscle scores, and macro recommendations—are approximations based on photo analysis and should not be used for diagnosis or treatment. Consult a qualified healthcare professional before making health or fitness decisions.

HealthPit reads your health data from Apple Health, lays it out clearly, and syncs it straight to your own Home Assistant — without a detour via anyone else's servers. YOUR AREAS Activity, heart, sleep, body, nutrition and vitals on a home screen you arrange yourself: move tiles, resize them, hide the ones you don't want. TRAINING Every sport with the figures actually recorded — duration, distance, pace, calories, heart rate, volume, sets, reps. Anything without data is left out rather than shown as an empty tile. Up to three figures can be compared in one chart. Plus personal records across every sport, manual workouts, and import from GPX and TCX. PAIN AND INJURIES A calendar that colours every day a complaint covered — not just the day it was entered. A two-week strain reads as two weeks. Anything you note during a workout turns up here on its own. DIARY For complaints that come in episodes: headache, migraine, panic attacks, dizziness, asthma, allergies. With severity, duration, the symptoms alongside and the possible triggers — and whether a medication helped. HealthPit shows you what comes up most often. That is the reason anyone keeps such a diary at all. EQUIPMENT Shoes, bike, and whatever else collects kilometres. From a date you set, a piece falls to the matching workouts on its own; a single workout can be assigned differently. Individual parts — chain, brake pads, tyres, insoles — carry their own intervals: by distance, by time, or by both, whichever comes first. CYCLE History, bleeding and symptoms, documented discreetly and written back. HOME ASSISTANT Values, workouts and goals arrive as sensors in your own instance. The integration is available through HACS. Automate whatever you like — from a closed ring to a reminder that the bike chain is due. YOUR DATA HealthPit has no account and no server of its own. Everything stays on your iPhone except what you send to your own Home Assistant. No tracking, no advertising, no third party looking at any of it. REQUIREMENTS Home Assistant is optional. Without a connection HealthPit simply shows your values on the iPhone. German, English, Spanish, French and Simplified Chinese.

Verdict
The clearest difference is in-app purchases: HealthPit at none against GainFrame's 8. GainFrame's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (75 vs 1). On price, rating, ads and device support there is nothing between them.
