What it shows

Six views of the data your devices already record. Each one keeps its own colour.

Home

Your week at a glance.

Each day is three nested rings: sleep, HRV and steps. Below them, the day's Sleep, Recovery and Movement scores as Ultrahuman gives them. A day with no records is left empty.

Score pages

Tap a score for the full page.

A photo hero with the gauge, then that section's details: total sleep, time in bed, restorative share, full cycles.

Sleep

The night as one flowing graph.

Awake, REM, light and deep as a single line moving between stages, with the time spent in each.

Activity

Steps, distance and calories against your goal.

Seven or thirty days at a time, compared with your own median. Show any chart as a table.

Workouts

A month of training, on one screen.

A heat map of workout days, time per activity type, and minutes per day or week over 7, 30 or 90 days.

Calendar and trends

Compared with your own recent median.

A ring on every day of the month for any metric. Trends compare each day with your own recent median, and missing days stay missing.

Private by design

Everything stays on your phone. No account, no server. These are the specifics.

Read the privacy policy
  • No account and no sign-in.Cordaya never sees a Google account or a password.
  • Health Connect is read on the phone.Through Android's own permission screen, where you pick which data types to allow.
  • One network call, and only if you ask for it.Ultrahuman's official API over HTTPS, only after you paste your token. Without a token, the app makes no network requests.
  • The token is encrypted.With the Android Keystore. App backups are turned off.
  • No analytics, ads or tracking SDKs right now.If opt-in usage analytics are ever added, they will never include health data.
  • Planned: a version with no internet permission at all.For people who don't use Ultrahuman.

Honest numbers

Not medical advice: Cordaya shows what your devices measured and doesn't diagnose.

  • 01
    Days without records are gaps, not zeros.A missing night is shown as missing, so your averages aren't dragged down by nothing.
  • 02
    Counted once.When two devices record the same thing, one source is used per measurement.
  • 03
    Vendor scores as the vendor gives them.Cordaya doesn't invent its own scores.

Questions

Is it on Google Play?

Not yet. A closed beta on Google Play starts soon. Join the beta group to get the invite link.

Does it work with my tracker?

If your tracker's app syncs to Health Connect, yes. Cordaya reads by type of data, not by brand.

Is my data uploaded anywhere?

No. It stays on your phone. The only exception is Ultrahuman, and only if you connect it: the app then asks Ultrahuman's API for your scores.

Is there an iPhone version?

No, Cordaya is Android only.

Is it a medical app?

No. It shows what your devices measured and doesn't diagnose or give medical advice.

What does it cost?

Most of Cordaya is free. A one-time Pro unlock is planned. No subscription, no ads, no account.
