GynoShift

Features
Read full description

GynoShift is a private daily companion for adult men navigating gynecomastia. It adapts to where you are: managing without surgery, researching, saving, preparing for a consultation, booked or recovering. AN HONEST START Answer a short assessment and, if you choose, run a private chest photo check for a rough educational read. It is not a diagnosis. Check images are analyzed for the result and discarded. A PLAN BUILT AROUND YOUR STAGE Follow a personalized 16-week plan covering the parts you can influence, with the limits explained clearly. • Training sessions for gym, home or no equipment • Progressive calibration based on your schedule and logged sessions • Body-composition, compression, posture and clothing guidance • Small confidence challenges that move at your pace • A clear next action each day PRIVATE, CONSISTENT PROGRESS Create a repeatable photo record with an alignment overlay, compare matching angles and track the changes that are too gradual to see day to day. Progress photos remain on your device or in your own iCloud—not on a server we run. SURGEON AND COST EVIDENCE When surgery is part of the decision, research candidates without sales pressure. Compare available credentials, techniques, caution flags and evidence. See published prices separately from costs reported by men, with sources attached where available. No surgeon can pay to appear higher, and GynoShift does not use star ratings to make a surgeon decision look simple. PREPARATION AND RECOVERY If surgery is booked, use a countdown, preparation checklist and private baseline. After surgery, the app provides a week-specific recovery map, compression guidance, photo checkpoints and a gradual return-to-training structure. Your surgeon's instructions always come first. THE BROTHERHOOD Join moderated rooms using an anonymous handle. Share perspective, join a private Circle and take part in consistency leagues built around showing up—not appearance or weight. SUPPORT IN THE MOMENT Power Mode is a short, offline grounding experience for moments when chest anxiety spikes. You can also receive optional weekly reviews and clearly labeled AI insights based on the activity you choose to record. APPLE HEALTH With your permission, GynoShift can read weight, step count and active energy from Apple Health to reduce manual logging and support body-composition progress. GynoShift does not write data to Apple Health. PRIVACY AND SUBSCRIPTIONS Available plans, prices and trial eligibility are shown before purchase. Subscriptions can be managed or canceled through your App Store account settings. GynoShift is for adults aged 18 and over. It is educational and does not diagnose a condition or replace a qualified clinician or your surgeon's instructions.
