Small wearables you already own record your body overnight — oxygen, heartbeat, pulse, glucose. Tepna reads each signal live and turns the night into one honest daily score.
Start with one — the more you wear, the fuller the picture. Each card shows its signal, live. See how to collect data →

Open HRVDex → GlucoDexFollows blood sugar around the clock, through the night.
Open GlucoDex → CPAPDexAdds how well your breathing was supported overnight.

A small mark on every number — disc shape, never colour — tells you measurement from estimate.
Read straight off the device.
Checked against a standard.
Published, device-dependent.
Plausible, not confirmed.
Rule-of-thumb direction.
Everything is read and combined on your own phone or laptop. No account, no cloud, no server holding your health. Close the tab and it's gone.
