Hidden Gainz, the no-audience fitness companion

Field notes

Hidden Gainz organizes fitness tracking around private, on-device records rather than a social graph. The described workflow covers workout sets, a rest timer, meal search with barcode and favorites, water in ounces, and body-weight goals. It also separates optional AI features from the core product: the page says meal-photo analysis and conversational coaching can use a user's own provider, while logging and training continue without that connection.
