HabitStack helps you build a morning routine that actually sticks. Instead of tracking habits in isolation, you stack small new habits onto the anchors you already do — your first coffee, brushing your teeth — so the whole routine flows in order and nothing gets forgotten. STACK HABITS ONTO ANCHORS Start from something you already do every morning, then stack new habits before or after it. Reorder the stack, set a duration and reminder per step, and build a sequence that feels natural. RUN YOUR MORNING AS A FLOW The Morning Run walks you through the stack one step at a time, so you move through the routine instead of staring at a checklist. A FORGIVING STREAK Keep one streak for the whole routine — with a built-in grace day, skip, and freeze, because one missed morning shouldn't erase weeks of progress. SEE WHAT'S REALLY STICKING The Momentum Engine scores how automatic each routine is becoming and estimates when it could feel effortless — an estimate grounded in habit research, never a promise. Watch your streak calendar and consistency trends build over time. HABITSTACK PRO (optional subscription) The routine builder, morning run, streak, and calendar are free. Pro unlocks multiple routines, your complete history, per-habit consistency, best-time-of-day and weakest-link insights, and shareable weekly reports. - $4.99/month or $29.99/year, with a 7-day free trial - Payment is charged to your Apple ID at confirmation; auto-renews unless canceled at least 24 hours before the period ends; manage or cancel anytime in your App Store settings.

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.
