🌿 Take a moment today to care for yourself.
⏱️ Ketone is a self-care app centered around intermittent fasting — track your weight, water intake, sleep, mood, and notes all in one place. Record and reflect on the small changes that happen every day.
🕐 Intermittent Fasting, Simple & Beautiful
Choose your plan — 16:8, 18:6, OMAD, or any custom duration — and just tap start.
From fat burning → ketosis → autophagy, see exactly what's happening in your body at each stage.
You'll get notified when you reach each milestone, so you can trust the timer and focus on your day.
Record your weight before and after fasting to see how your body changes with each session.
📸 Fasting Results & Sharing
When you finish a fast, get a clear summary of your duration, stages reached, and weight change.
A streak card and stage-journey timeline make your consistency visible.
Save your results as a beautiful image or share them with friends to celebrate your progress.
Even mid-fast, share your live timer in two styles — full timer or compact card.
