Weight tracking is a small job done daily, and Luff treats it that way. Have a normal weekend without the app sulking about it. Plot a new course from where you actually are, not where you wish you were. How it works Pick a direction: lose, gain, or maintain. Step on your scale; Luff syncs with Apple Health. Hit your goal and Luff shifts you to maintenance automatically. What's included: Weight logging with Apple Health sync. A smoothed trend line instead of daily noise.

About

Rosacea Flare Trigger Tracker

Features
Read full description

Living with facial rosacea means noticing the flush—and wondering what set it off. Rosacea gives you a calm place to track flares, log likely triggers, and see patterns over time. Check in on redness, burning, dryness, and more in seconds. Note stress, sun, spicy food, skincare, weather, and the rest of your day. Over weeks, your history helps you talk clearly with a dermatologist—without guessing from memory. What you can do: • Daily skin check-ins with a simple flare score • Trigger logging that fits real life • Trends, photo progress, and routine tracking • Private by design—your diary stays on your device • A clear history when you need it for a visit Built for sensitive facial skin. No account required. Not a diagnosis—just a clearer picture of your own patterns. Rosacea is for personal tracking and awareness only. It does not provide medical advice. Always follow guidance from your dermatologist or healthcare provider.
