DietConnect: Weight Diary

Dieting, one number is enough. No meal logs. No workout tracking. No calorie counting. No photos. DietConnect is a minimalist diet companion where you enter just one number a day — your weight. Zero logging burden, and an AI character who watches over you every day. WHO IS IT FOR - Anyone who quit a diet-tracking app after a few exhausting days - Anyone who gave up dieting over daily weight swings - Anyone who wants warm encouragement, not nagging - Anyone who feels alone but finds social check-ins too much KEY FEATURES One Number a Day - Just enter today's weight once - Automatic 7-day and 14-day moving averages filter out daily noise - Streaks reward consistency Four AI Characters with Distinct Personalities - Dohyun (calm coach): reads trends and averages, steady and clear - Bom (warm cheerleader): praises you just for showing up - Gyeoul (tsundere friend): acts prickly but always has your back - Noa (data analyst): MA7, MA14, deviation — dry and precise - Switch characters anytime with a gentle farewell ritual Safe Encouragement (shared by all characters) - Daily swings are normal; guidance points to the 7-day trend - The gentler it gets, the more your weight went up that day - Rapid loss is flagged as a concern — health first - No calorie, fasting, or specific-diet prescriptions - Never reinforces negative self-talk Trend at a Glance - Current weight, change since start, remaining amount and progress - Weight chart with moving averages over 7-day / 30-day / all ranges - Per-date history with day-over-day deltas Quality - Material 3 design, automatic dark mode - Pretendard Korean font bundled — identical output across devices - No account, no login, all data stays on the device Data Notes - Nickname, weight, and goals are stored locally on the device. - Uninstalling the app removes the data with it. - To generate AI character replies, a summary of your weight trend may be sent to an AI server; no personal identifiers such as your name are sent. (If the server call fails, replies are generated by on-device rules.) - Free to use, with ads.
