About
Fasting is a quiet, focused intermittent fasting tracker for iPhone — no accounts, no servers, no analytics. Your data lives only on your device.
WHY FASTING
Most fasting apps want your data, your email, and your attention. Fasting just wants to help you keep time. It's local-only by design: every session, goal, and preference stays on your iPhone, in Apple's secure app sandbox. No sign-in, no cloud, no third parties.
LIVE ON YOUR LOCK SCREEN
Live Activities keep your current fast (or eating window) ticking on the Lock Screen and in the Dynamic Island. No need to open the app to see how long you've been going.
FASTING STAGES
Watch your body shift through six stages on a clean timeline:
• Fed — insulin high, glucose fueling you
• Early Fasting — blood sugar drops, digestion winds down
• Metabolic Switch — liver glycogen runs low, ketosis begins
• Enhanced Fat Burning — fat is the primary fuel
• Ketosis & Autophagy — cellular cleanup ramps up
• Deep Ketosis — sustained ketone production
CHOOSE YOUR STYLE
• FreeStyle — just press start and go. No goal, no pressure.
• Goal mode — set a fasting/eating window like 16:8, 18:6, or your own. Watch the ring fill as you progress.
INSIGHTS
Review your fasts on a simple chart. See your trend, your streak, and your longest fast — without anyone else seeing them.
PRIVACY, BUILT IN
• No accounts. No sign-in. Ever.
• No data leaves your device.
• No analytics, no tracking, no advertising SDKs.
• No push servers — Live Activities run on-device through Apple's ActivityKit.
• Delete the app and your data is gone.
