Set a target. Hit it. WeightTarget turns your weight goal into a clear plan β€” and shows you exactly how you're doing at every step. Pick your start weight, target weight and date, and WeightTarget plots your path: a target weight for every weigh-in, daily to monthly. Log your weight on the custom number pad (or straight from Apple Health) and every checkpoint is marked Hit or Missed, with your progress, pace, and weight-to-go always in view. APPLE HEALTH, TWO-WAY Connect Apple Health and your weigh-ins flow both ways β€” today's weight from your smart scale appears automatically, your history backfills new goals, and everything you log is written back to Health. Always on your terms: nothing syncs without your permission. ADAPTIVE TARGETS Bad week? Optional adaptive mode recalculates your upcoming targets from your latest weigh-in, so you always have an achievable path to the same end date. PROGRESS PHOTOS β€” COMPLETELY PRIVATE Take or import progress photos and watch your before & after develop. Photos live inside the app, never your camera roll, protected by Face ID or a PIN. ALSO IN WEIGHTTARGET β€’ Full weight history chart β€” scroll through time, see highs, lows and averages β€’ Multiple goals at once, in kg, lbs or stone β€’ Light, dark and pink themes β€’ App lock with Face ID, PIN or password β€’ Backup & restore to a file you control β€’ No accounts, no ads, no tracking.

LightYet does not require an account and contains no advertising or third-party analytics SDKs. Non-AI records are stored on your device. If you enable iCloud sync, supported data is stored in your private iCloud container. AI features are optional. Only after you agree and request an AI feature, selected information needed for that request may be sent to LightYet's AI processing service. Depending on the feature, this may include a meal photo or description, your question, and relevant profile, weight, body-fat, or calorie summaries. Progress photos are not included in AI body trend reviews. AI estimates can be inaccurate and should be reviewed before saving. Nutrition targets are planning estimates, not medical prescriptions. LightYet is not a medical device and does not replace professional medical advice.
