hæl vs Phasely

hæl is a fasting timer that observes instead of coaching. the app watches the hours, reads the cycle, and reflects what it sees in prose. no prescription. no congratulation. most fasting apps count down and celebrate. hæl counts and stays quiet. the interface is a single ring. the language is literary. the body's rhythm shapes what the app says and when. THE FAST an ensō ring marks the hours. drag to choose a duration, tap to begin. the timer carries a name that changes as the fast deepens. lauds, prime, terce, vespers. names borrowed from the canonical hours. prose arrives about what the body is doing, not what it should do. overtime continues past the goal without comment. a day can be marked as rest instead, held without penalty. the first week is witnessed from the start, free. THE CYCLE hæl reads the menstrual cycle through Apple Health. the ring tint shifts with the phase. fasting windows adjust. shorter during menstruation, longer during follicular. weight is read in cycle context. a gain during luteal is not a gain during ovulation. the app knows the difference, and across enough cycles it learns the pattern, marking when today confirms what the body has already shown. cycle tracking is optional. non-cycle users receive their own prose register, rotating by month. THE WEIGHT a constellation sparkline tracks weight over time. each point a breathing star. the app reads the trend and writes one observation. no graphs demanding interpretation. one line of prose. THE LETTERS weekly letters arrive on mondays. a retrospective of the week. the fasting, the weight, the cycle. written in the same quiet voice. monthly readings take the longer view. quarterly readings mark the turn of each season. once a year, a year-in-review colophon gathers the whole arc into one page. in the ledger, a correspondence appears, one letter at a time, on the ensō, the canonical hours, the luteal phase, autophagy, the colophon. dismissed when read. a finite pool that goes quiet when the last page turns. THE COLOPHON when a fast ends, a page stays. the date spelled out, the hours witnessed, a line composed from what happened. a small ceremony for something the body did. shareable. THE LEDGER a bound record of every fast, grouped by cycle or by month. the current group is open. past groups fold to a spine, a date range and a spelled-out count. tap to unseal the colophon beneath. THE PRACTICE hydration tracking with eight water drops. notifications that observe the season, the morning, the phase. never demanding, always noticing. live activities on the lock screen and dynamic island. siri shortcuts for starting a fast or checking the hours. apple watch companion with a complication that carries its own witness line. ipad support. THE FULL WITNESS (one-time purchase, $19.99) the free app sees the fast. the full witness sees the cycle. the ring becomes phase-aware. body readings gain context. weekly letters, monthly readings, quarterly readings, and the year-in-review arrive in full. weight tracking reads the cycle. the ledger letters appear. milestone ceremonies mark the long stretches, seven days, thirty, ninety, a year. fasts beyond twenty-four hours unlock. one purchase, nothing recurring. PRIVACY all data lives on-device, in Apple Health, and in a private iCloud container. no account. no server of ours sees it. once Apple Health holds a weight or cycle entry, hæl stops mirroring that entry to iCloud and lets Health carry it between devices instead. hæl uses standard HTTPS for StoreKit and anonymous, privacy-first telemetry. nothing else. hæl is not a medical device. it does not diagnose, treat, or prescribe. fasts beyond forty-eight hours should be medically supervised. the app says so every time.

Phasely is a fasting app built for women's bodies — not a generic fasting tracker with pink branding. Most fasting apps treat every day the same. But your hormonal cycle changes everything: how you respond to fasting, what your body needs, when to push and when to rest. Phasely adapts fasting windows to your current phase — shorter in the late luteal phase when cortisol is sensitive, longer when estrogen and energy are climbing. — FREE AT LAUNCH — The entire app is free. Track your cycle, see your phase, use the timer, log meal photos, and chat with the AI coach. A premium tier with unlimited coach queries is planned for a future release. — FEATURES — CYCLE-AWARE FASTING Personalized fasting window suggestions for each of your 5 phases: Reset (menstruation), Build (follicular), Peak (ovulation), Sustain (early luteal), and Soften (late luteal). No more pushing 16-hour fasts when your body needs an earlier breakfast. AI COACH GROUNDED IN REAL RESEARCH Ask anything — about fasting, hormones, energy, training, hunger, mood. The coach draws from peer-reviewed research and 6 expert camps including Dr. Stacy Sims, Dr. Mindy Pelz, Dr. Aviva Romm, Alisa Vitti, Dr. Jen Gunter, and Dr. Mary Claire Haver. Every answer cites its source. Free version includes 10 coach queries. PHASE-AWARE TIMER Recommended fasting windows pre-fill based on your current phase. Track active fasts. See progress at a glance. MEAL PHOTO INSIGHTS Snap a photo of what you're eating. Phasely identifies the foods, checks for inflammation markers, and ties insights back to your current phase. CYCLE TRACKING Log periods, see your phase forecast, and understand hormone curves through each part of the month. Visualize where you are now and what's coming. HEALTHKIT INTEGRATION Sync menstrual flow data with Apple Health for unified tracking. Never enter your period twice. GROUNDED, NOT GUESSED Phasely's recommendations come from 160+ peer-reviewed studies and clinical guidance from women's health specialists. Where experts disagree, Phasely shows you the camps and lets you decide. — BUILT WITH CARE — PRIVATE BY DEFAULT Your data stays yours. Export everything anytime. Delete your account and all data permanently with one tap. Apple Health data never leaves your device unless you choose to sync it. NOT MEDICAL ADVICE Phasely is educational. We surface research and frameworks but don't diagnose, prescribe, or replace your doctor. If something feels off, see a professional. NO ADS, NO TRACKING No third-party advertisers. No selling your data. No newsletter spam. Just the app. — WHO IT'S FOR — Phasely is designed for women aged 18+ who are cycling, perimenopausal, or postmenopausal. Whether you're new to fasting or experienced and ready to make it cycle-aware, Phasely meets you where you are. It is NOT appropriate for: anyone with current or past eating disorders, pregnant or nursing women, those with type 1 diabetes, anyone underweight, or anyone whose doctor has advised against fasting. The app screens for these during onboarding. — FROM THE FOUNDER — I built Phasely because I couldn't find a fasting app that treated women's bodies seriously. Every tool I tried was either a generic tracker with pink colors or a one-size-fits-all protocol that ignored my cycle entirely. Phasely is the app I wanted — grounded in real research, respectful of how women's hormones actually work, designed to support not control. — PRIVACY & SUPPORT — Privacy Policy: https://phasely.today/privacy Terms of Service: https://phasely.today/terms Medical Disclaimer: https://phasely.today/medical-disclaimer AI Safety Policy: https://phasely.today/ai-safety Support: hello@phasely.today Built in Zürich.
