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.

Blimbi
Read full descriptionHide full description
Blimbi is the intermittent fasting tracker that stays clear, private and pressure-free. No ads and no rigid rules. You choose when to start and stop. Pick 12:12, 14:10, 16:8, 18:6, 20:4 or another rhythm. Your reference time guides you but never starts or ends a fast automatically. Eating mode clearly separates your current eating window from the next fasting goal. THE ESSENTIALS, DONE WELL • Live timer with goal, time remaining and clear backdated edits. • Editable journal, weekly overview, calm milestones and CSV export. • Educational metabolic stages shown as approximate ranges, never measurements. • Illustrated quick reads about drinks, returning to food, evidence and safety. • Widgets, Live Activities, Shortcuts, Apple Watch and configurable reminders. • End-to-end encrypted backup with your Apple or Google account. • No ads. BLIMBI PLUS Build a custom weekly rhythm, add a clinician's comment, and prepare an assisted draft that you always review before saving. Plus also expands insights and personalization. Price and terms are shown before purchase. Blimbi is not a medical device. It does not diagnose, treat, cure, prevent or measure any condition or metabolic process, and it is not a substitute for professional care. If you have diabetes, take medication, are pregnant or breastfeeding, consult your healthcare team first. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
