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.

SilverStrong is built for people over 50 who want to move well at home — without a gym, without a class, and without guessing whether any of it is working. START WITH A NUMBER, NOT A GUESS The Check is a five-minute test you do at home: how many times you can stand from a chair in 30 seconds, and how long you can hold four balance positions. Your result is scored against the published figures for your age and sex, so you know where you actually stand. A SESSION BUILT FOR TODAY Every session is assembled to the length you choose, from movements you can actually do — seated, holding on, or free-standing — and it leaves out anything that loads a joint you have told it is sore. IT LISTENS, AND IT CHANGES Rate the effort and any pain at the end, answer one question the next morning, and the plan moves. Two clean sessions and it steps up. Pain, or soreness that is worse the next day, and it eases back. The reason is written on the screen in plain words every time. THE THREE WEEKLY TARGETS Moving minutes, strength days and balance days, tracked separately against the World Health Organization's weekly numbers for adults. Balance is the one almost nobody counts. BUILT FOR THE EYES AND HANDS THAT WILL USE IT Large type, high contrast, generous buttons, spoken instructions so you can look away from the phone, and a light and a dark theme. It works on iPhone and iPad. FREE, AND IT STAYS FREE The Check and its score, a complete session every single day, the whole movement library, the three weekly targets and every safety behaviour are free — permanently. SILVERSTRONG PLUS (optional subscription) - Unlimited re-Checks, your trend line, and a projected date you reach the published average for your age - Sessions that step up on their own, plus 20 and 30 minute lengths - Your stiffness compared across session days and rest days - A printable session sheet and a summary page you can hand your doctor - Your full history $6.99 a month or $39.99 a year, after a 7-day free trial. Payment is charged to your Apple Account at confirmation. It renews automatically at the same price unless you turn off auto-renew at least 24 hours before the end of the period, and you can manage or cancel it any time in your Apple Account settings. SilverStrong is a wellness tool, not medical advice. If something hurts, changes, or worries you, talk to your doctor.
