Take a quick body photo every day and watch your progress turn into a smooth timelapse video. FormLapse auto-aligns position, tilt and scale, so you don't need to line up a ghost overlay or use a tripod. Casual shots are fine. Your photos never leave your iPhone: no network connection, no account.

Me then. Me now. Same pose. Same angle. See what changed. The scale misses some visible changes. Aligned photos help you see them. MeThen turns progress pics into a comparable record of your bulk, cut, or recomp. Slide between check-ins, with an optional, non-medical AI read. MeThen is a privacy-first progress-photo tracker for lifters who trust the mirror over the scale. Guided check-ins keep every photo shot the same way, your timeline and compares are stored locally, and AI sees photos only for actions you start. HOW IT WORKS 1. Check in: capture front, side, and back with on-screen alignment guides and a self-timer, so every check-in lines up with the last. Got old pics? Import them as backdated check-ins and your timeline builds itself. 2. Watch the trend: browse your timeline and compare any two check-ins side by side — free, unlimited, and entirely on your device. 3. Want a second opinion? Tap Analyze — the first two are free — for a careful, non-medical read of what changed. Choose Cut, Bulk or Recomp. Optional Sunday reminders, streaks and countdown widgets support your weekly ritual. Share a GIF made on your device. Pro Deep Compare adds a photo-based verdict and a V-taper estimate when photos allow. WHAT AN ANALYSIS GIVES YOU • What visibly changed — shoulders, chest, waist, arms, posture, leanness, symmetry — in plain language. • The trend since your last check-in, claimed only when your photos are consistent enough to trust it. • A body-fat estimate as a broad range, clearly labeled a rough guess from photos — never fake-precision decimals. An optional height, weight, or measurement sharpens it locally and is never sent by MeThen. • A better-photo suggestion when lighting, angle, or clothing would make any read unreliable — instead of a guess. • Follow-up questions: 10 successful replies a day free. Pro removes the daily reply cap for normal personal use. DEEP COMPARE (PRO) Pick any two check-ins and Deep Compare sends both sets of photos to the AI so it reads the change directly: leaner or softer, and by roughly how much — sharper than comparing summaries. It asks for your OK first, every single time. HONEST BY DESIGN No scores, no grades, no shame. MeThen describes what the camera shows, gently — and when lighting, pump, or time of day could exaggerate a change, it says so instead of inventing progress (or panic). It is a fitness tool, not a medical one: every result carries a non-medical disclaimer and body-fat figures are estimates, not measurements. A wellbeing page is one tap away if the numbers stop helping: https://lightpathapps.com/apps/methen/wellbeing/ PRIVATE BY DESIGN Your photos and check-ins are stored on your device, with no sign-in, ads, or tracking. When you tap Analyze, Gemini receives the selected photos, its journal note, and a compact prior-result summary if available; Deep Compare sends both sets. Photo metadata is stripped and requests aren't used to train models. Google may retain request data temporarily for safety or caching, as detailed in the privacy policy. Chat never resends photos. PLANS & PRICING Free: unlimited check-ins, timeline, side-by-side compare, 2 AI analyses, and 10 chat replies a day. Pro: unlimited AI analyses, Deep Compare, and follow-up chat for normal personal use. Pro is available monthly or yearly. The App Store shows your local price and any introductory offer for which you're eligible. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. Payment is charged to your Apple ID, and you can manage or cancel anytime in your App Store account settings. Terms of Use: https://lightpathapps.com/apps/methen/terms/ Privacy Policy: https://lightpathapps.com/apps/methen/privacy/ MeThen gives general, non-medical fitness observations from photos. It is not medical advice, and body-fat figures are broad estimates, not measurements.
