About this app

Nouring turns your ring's data into a dashboard that lives on your phone alone.

No account, no server, no cloud sync: the app talks to the ring directly over
Bluetooth and keeps everything in a local database. The release build does not even
hold the permission to access the internet.

Nouring reads what the ring itself offers over Bluetooth: nothing to sign up for,
nothing to renew.

WHAT YOU GET

• Sleep — the night's hypnogram, stages (deep, light, REM, awake), duration,
efficiency and latency. Slept in more than one stretch? Each session stays its own.
• Heart rate & HRV — heart rate through the day, nightly HRV and resting heart rate,
with weekly, monthly and yearly trends.
• SpO2 — nightly saturation, the night's minimum and a reference band.
• Temperature — skin temperature and its deviation from your own baseline, not from
a generic average.
• Scores — sleep, readiness and energy, computed on the phone from your own data.
• Ring battery — always in sight, with an optional ongoing notification.

HOW IT WORKS

Wear the ring, open the app, and the data comes down over Bluetooth. Nights already
downloaded are not fetched again, and days you did not wear the ring stay empty
instead of being filled with estimates.

EXPORT

• Health Connect: the app writes sleep, heart rate, HRV, resting heart rate and
temperature, so other apps can read them. Write-only — Nouring reads nothing back
from Health Connect.
• CSV, whenever you want.
• A backup of the ring key, so you never lose access to it.

LANGUAGES

English, Italian, German, Spanish. Light and dark theme.

REQUIREMENTS

Android 13 or later, Bluetooth and a compatible ring. The app was built and tested on
generation 3 (Horizon). Generations 4 and 5 use the same protocol and should work, but
they have not been tested.

DISCLAIMER

Nouring is not a medical device. Its data and scores are for information and
wellness only; they are not meant to diagnose, treat or prevent any disease. Talk
to a doctor about anything concerning your health.

The name stands for "not our ring": the ring is yours, and so is the data on your
phone. Nouring is an independent app, not affiliated with, endorsed by or sponsored
