GynoShift

Gyno. Puffy nipples. Male breast tissue. GynoShift is the iPhone app for men with gynecomastia, from the first check to full recovery. SEE YOUR CHEST WITHOUT GYNO Take one photo and GynoShift draws your goal: your own chest, flat and masculine. It's an illustration of where you're heading, not a promise, and both images stay on your phone. CHECK GYNO OR FAT. KNOW YOUR GRADE. A private photo check and a few questions about how the tissue feels give you an educational read on gland versus fat, with a grade. It's an estimate, not a diagnosis, and the app always says so. TACKLE PUFFY NIPPLES AND CHEST FAT WITH A 16-WEEK PLAN โข Sessions for the gym, dumbbells at home, or no equipment โข Never trained? It starts you gently at 2โ3 days a week โข Food targets that adjust to your weight trend โข Compression, posture and clothing guidance โข One clear thing to do today TRACK YOUR CHEST EVERY 2 WEEKS A reading every fortnight: a photo over a ghost of your last one, plus the tape at the nipple line. Your numbers sit on one chart with the normal noise shown, so you know whether it's really changing. PLAN GYNO SURGERY, FROM PRE-OP TO RECOVERY If surgery is your route, the Path plans it: whether it fits you, the pre-op checklist, the day itself, and a recovery map from day one to full recovery. COMPARE GYNO SURGEONS AND REAL PRICES Surgeons with sourced facts, quoted from their own practices, and what men actually paid. No surgeon can pay to rank higher. TALK TO MEN WITH GYNO, ANONYMOUSLY The Brotherhood: men at your week of the plan or your day after surgery. Anonymous handles, no faces, no chest photos in the feed. PRIVATE BY DESIGN Progress photos stay on your phone. Photos sent for a check aren't stored. No ads, no data sales. GYNOSHIFT PRO One subscription unlocks everything, yearly or monthly. Payment is charged to your Apple ID, and the subscription renews automatically unless you cancel at least 24 hours before the end of the period. Manage or cancel anytime in your App Store account settings. GynoShift is an educational companion for adults, not a medical service. Nothing in the app is a diagnosis or medical advice; a doctor who examines you is the definitive answer. Terms: https://gynoshift.app/terms Privacy: https://gynoshift.app/privacy
