FastingForge is a calm, offline intermittent fasting timer. One tap starts your fast — then the Tempering Ring shows which science-backed stage your body is typically in, and how long until the next one. THE TEMPERING RING A live dial that heats from cold slate to molten gold as your fast runs. Each milestone — blood sugar settling, glycogen depletion, fat burning, ketosis, autophagy — ignites as its hour is reached, with a plain-language note on what is happening. HONEST ABOUT THE SCIENCE Every stage carries an evidence badge: well established, individually varies, or animal-model. FastingForge estimates from the clock; it never claims to measure your body. It is a general wellness and educational tool, not medical advice. WORKS WITHOUT A SIGNAL The timer, the milestones, your history and your reminders all run on your device. No account needed, no feed, no articles, no upsells mid-fast. EVERYTHING THAT MATTERS IS FREE The timer and the Tempering Ring, every protocol (13:11 through 20:4, OMAD, custom and extended), your full fasting history, streaks and stats, the complete stages library, this month's calendar, achievements and offline reminders — free, forever. FORGE PRO (optional subscription) - Weekday consistency analytics and the full trend breakdown - Weight logging, plus an honest read on how your weekly fasting hours line up with your weekly weight change - Full-history calendar and shareable milestone cards - 7.99 USD per month or 49.99 USD per year, with a 7-day free trial for eligible new subscribers - Payment is charged to your Apple ID at confirmation. Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings. Fasting is not right for everyone. Talk to a doctor before fasting if you are pregnant or breastfeeding, under 18, diabetic, taking medication, or have a history of disordered eating.
