About

Acne Tracker

Read full description

Track your acne with a forgiving daily routine, a same-position photo timeline, and an honest AI read of every photo so you can see what's actually changing. No fake severity scores, no "pay per scan," no shame. Acne Tracker is built for adult acne, hormonal breakouts, Accutane and Tretinoin journeys, and back & body acne. Take a 90-second quiz to get a personalized AM/PM routine, mark each day's check-in done, and watch a real photo timeline — with a clear, hedged AI summary — tell the story. WHAT YOU GET FOR FREE • 7-question skin quiz: skin type, breakout zones, treatments, sensitivities → personalized routine • AM and PM check-ins with a forgiving "did you do PM last night?" backfill • Streak counter, late-night grace until 3 AM, calendar with current and previous month • Up to 5 products and 30 progress photos • Front-facing camera with a face-positioning oval guide • Honest AI read on every photo: severity score, region breakdown, lesion counts • AM and PM reminders • Trigger journal: stress, sleep, dairy, sugar, cycle day • Weekly summary • Basic badges PREMIUM UNLOCKS • Barcode scanner with Open Beauty Facts + Open Food Facts lookup • Ingredient compatibility check against your skin profile and routine • Unlimited products and unlimited progress photos • Multi-angle photos (cheeks, chin, forehead, body) • Compare any two photos side by side • Trigger correlations: cycle, dairy, sleep, stress • Monthly reports • PDF export for your dermatologist • Treatment mode: Accutane, Tretinoin, Spironolactone — day-count and side-effect log • Per-product reminders, breakout-prep alerts • 1 silent grace day per 30 days • Manual spot annotation • Premium badge collection • iCloud sync across your Apple devices Premium Monthly or Premium Yearly. Subscriptions auto-renew until cancelled. Manage anytime in Settings. WHY IT'S DIFFERENT • Honest AI, not hype. Every photo gets one clean analysis pass with hedged language ("trend suggests," "possible pattern") — never medical claims. • No "pay per scan." No "refer 3 friends to unlock." Free works standalone for at least 14 days of real use. • Forgiving streak rules. Late-night grace until 3 AM, one-tap backfill for yesterday, silent grace days. We never shame you for missing a day. • An ingredient checker that knows your routine. Verdict cards say "may not be ideal" — never "BAD FOR YOUR SKIN." • Treatment mode for Accutane and Tretinoin without paywalling everything else. • Your data stays on your device. Photos sync via your private iCloud Photos library, never through our servers. WHAT IT IS NOT This is a tracking tool, not medical advice. The AI read is informational — a photo summary, not a diagnosis. For medical concerns, please see a dermatologist. PRIVACY No sign-in required. No ads. Your products, routines, photos, check-ins, and trigger logs live on your device. When you take a progress photo, the cropped face frame is sent to our server for one analysis pass and the result is stored locally — no biometric face ID, no facial recognition, no third-party sharing. Anonymous product analytics only (you can opt out). Photos sync via your private iCloud Photos library, never through our servers.
