A one-thumb arcade game with 600 hand-built levels and no waiting.

Log how the day actually went — energy, mood, cramps, cravings, sleep, a meal — and see it laid out against where you are in your cycle. It looks for repetitions over months and says plainly when it does not have enough of them yet.
Not on the stores yet. A finished interface with simulated services. Not submitted anywhere.

Interactive recreation
The words are Auren’s, in ten languages including Arabic right-to-left, copied out of the app’s own string table rather than rewritten for this page — because the hedging in them is the product. The history behind the chart is the app’s sample fixture, which the app itself marks as fictional, and the insight at the end is deterministic: the same taps produce the same sentence every time. Nothing you enter leaves your browser, nothing is stored, and no part of this is a health record or a health claim.

Why it exists
Cycle apps predict, food apps count, and both tend to assert more than they know. The uncomfortable part of the category is that a personal pattern needs months of repeated evidence before it is a pattern at all, and an app that says so sounds less impressive than one that does not. Auren is built around saying so: it connects the signals a body actually gives in one record, and it distinguishes what it has seen from what it has inferred.
What it does
Energy, mood, cramps, tenderness, bloating, cravings, sleep quality, flow, activity and meals, logged in a few taps and readable together. Missing signals stay blank rather than being filled in.
Meals are logged with a photo-assisted flow and always correctable by hand. There is no daily target, no streak and no deficit — the point is what a meal coincided with, not what it cost.
Three hundred and fifty keys across ten languages with a full right-to-left layout in Arabic, locale number and date formatting, metric or imperial, and a reduced-motion setting.
It works without an account. Records stay on the device, and everything logged can be exported as JSON or shared as plain text — including a view intended for showing a clinician.
How it was built
The three learning states are part of the data model, not a loading screen: new, learning, and pattern-found. Until there is enough repeated history the app shows how many days of signals it has and declines to offer a personal forecast, in ten languages, in its own words — "a personal forecast needs reliable patterns first". The sample history is flagged at the record level too, so a fictional demo insight can never be presented as an inferred personal result. That single flag is what makes a product tour safe to ship inside a health app.
Where it stands
A complete, interactive interface built on simulated services. Nothing is uploaded, no health permission is requested, no camera is opened and no charge is possible. Auren makes no medical claim: it does not diagnose, treat or predict a health outcome, and its own copy is written to keep that true. It is in the Lab because every service behind the screens is still a local simulation. Its application identifier stopped being the Expo example default on 25 September 2026, which removed the reason it could not be submitted rather than the reason it has not been.
