Fastoria

About

Fastoria is your companion for intermittent fasting — a clean timer, rich health charts, and the science behind every phase of your fast. TRACK YOUR FAST Tap once to start. A live countdown guides you through each fasting phase — from fat burning at 12 hours to deep ketosis and autophagy beyond 24 hours. Milestone notifications keep you motivated without interrupting your day. Tap again to end your fast and log it instantly. UNDERSTAND YOUR BODY With a Fasting Insights subscription, Fastoria reads your Apple Health data and charts it against your fast in real time: • Heart rate & resting HR — watch your pulse settle as fasting deepens and your cardiovascular system shifts into recovery mode • HRV — monitor autonomic nervous system recovery hour by hour throughout your fast • Blood glucose — see your levels stabilize and drop as insulin falls and fat burning begins • Body weight — track the trend across multi-day fasts and see real progress • Combined view — all four metrics on one synchronized timeline so you can spot correlations at a glance Every chart is built from your own Apple Health data — the same readings your Apple Watch already captures. Fastoria just brings it all together in the context of your fast. HISTORY & STREAKS A color-coded calendar shows every completed fast at a glance. Shorter fasts appear in one shade, longer fasts in another — so your consistency is visible from across the room. Tap any day to review the details. Build your streak, spot your patterns, and celebrate milestones over time. BACKED BY SCIENCE The Learn tab links every fasting phase to peer-reviewed research. Understand the glycogen depletion that begins at hour four, the growth hormone surge at twelve hours, the ketone production that kicks in at eighteen, and the cellular autophagy that accelerates beyond twenty-four. Each milestone is grounded in published science — not wellness folklore — so you always know what your body is actually doing and why. PRIVACY FIRST Your health data never leaves your device.
