An app, finally, that reads what her body has been telling her — across sleep, mood, energy, recovery, the immune system, the gut, the heart, the cycle, the long seasons of a life. Apple Health and Oura have been writing it down for years, with almost no one to read it back. Nar is that reader — quiet, on her phone alone, fluent in every life stage. Built for women, only, and unapologetically so.
Open Nar on the App StoreFor her — across the long span her body moves through. The good sleep and the broken. The mornings of energy and the mornings of nothing. The heart that races for no reason she can name. The skin that runs warm before she catches a cold. The mood that turns sharper than the situation calls for. The gut that quiets, then complains. The headache she could see coming, days before it came. The cycle that becomes the after; the after that becomes a new normal. Nar reads through all of it, in the language of physiology rather than the language of wellness — on her phone alone, the way a woman's body has always been read by women who paid attention.
I built Nar after watching the women in my life — postpartum, in perimenopause, navigating cycles their textbooks couldn't describe — receive a great deal of advice and very little explanation. The numbers were there. The reading was missing. Women have always been the readers of their own bodies; only the writing has changed. Nar is the reader who can read in numbers. It is small, slow, lives only on your phone, and speaks plainly. It does not prescribe. It translates.

Nar is an iPhone app that reads Apple Health and Oura Ring data on-device and turns it into plain-language daily readings across nine domains of women's health. Every reading is computed against the woman's own personal baseline — a rolling standard deviation, not a population average — and filtered through one of six life-stage lenses: cycling, postpartum, perimenopause, menopause, and post-menopause.
The model behind it was trained on 71 million days of real women's physiology from the public LifeSnaps research dataset, runs as a CoreML temporal encoder entirely on the iPhone, and never leaves the device. The only optional outbound call is the Oura API, which the user opts into.
Nar is not a cycle tracker. The menstrual cycle is one of nine domains and one of six lenses, never the lead. Nar is built for women across the long span — including postpartum (where a 25 ms HRV is normal, not critical), perimenopause, and the years after — and it reads each life stage on its own terms.
Nar's strongest validated prediction is musculoskeletal pain and tension, twelve to twenty-four hours in advance. The pattern combines a high sedentary day, an HRV already suppressed below personal baseline, and a sudden activity contrast the next day. The onset marker is an intra-hour heart-rate spike of roughly twenty-three beats above resting average. After the event, Nar follows the recovery cascade — the HRV ceiling collapsing over three nights, deep sleep falling about thirty-six minutes, the skin running cold — so the woman knows what she is recovering from, and for how long.
Nar is an iPhone app that reads what a woman's body has been recording. It interprets Apple Health and Oura Ring data on-device across nine domains of women's health — sleep, mood, body, energy, gut, heart, immunity, pain, and hormonal — and translates the readings into plain language.
No. The menstrual cycle is one of nine domains and one of six life-stage lenses, not the lead identity. Nar is a holistic women's health reader designed for cycling, postpartum, perimenopause, menopause, and post-menopause.
Oura records the data. Nar reads it. Nar runs entirely on the iPhone, reads Apple Health and Oura together, uses personal baselines instead of population averages, applies life-stage lenses, and traces every reading to a published physiological mechanism.
Nar's strongest validated prediction is musculoskeletal pain and tension twelve to twenty-four hours in advance, combining sedentary load, suppressed heart-rate variability, and sudden activity contrast. Nar also reads cycle-phase physiology, the recovery cascade after pain or illness, and multi-domain convergence.
Yes. Nar is 100% on-device. The only optional outbound network call is the Oura API pull, which the user opts into. There are no servers, no telemetry, and no analytics.
Nar costs £5.99 per month or £44.99 per year, with a one-month free trial. The free tier includes daily cards, logging, sleep readings, the cycle lens, and the personal baselines engine.
Nar runs on iPhone with iOS 26. It reads Apple Health — whichever metrics Apple Watch, the iPhone, or any connected source has written into it — and, optionally, the Oura Ring via the Oura API.
Nar is built by Cognitive Intelligence Development (CID), founded by Benan D. Allan, PhD in Brain, Mind, and Computer Science (Padova and Edinburgh), previously Head of Science and AI at Stardust.
