Questions No Single App Can Answer

When your sleep, workouts, blood pressure, and spending live in separate apps, the questions that span them go unanswered. In one history, they line up by time.

  • Do you sleep better on days you exercise?

  • How has your blood pressure changed over a decade?

  • Are you spending more than you earn?

Correlations puts up to five metrics on one chart, by day, week, or month. Discover, part of Kaizora Plus, ranks every pair of your metrics by how strongly they move together, including a few days apart.

Five Areas, One History

Hundreds of metrics, grouped where you’d look for them. Each area opens on its most useful chart, then what’s changing and what’s out of range.

Every Metric Exactly Defined

Two numbers that measure different things are two metrics, so a chart never mixes them. Some examples:

Heart Rate Variability (SDNN) and Heart Rate Variability (RMSSD)

Two measures of HRV that give different numbers.

VO₂ Max and Estimated VO₂ Max

A maximal test, or a watch’s estimate.

LDL Cholesterol (Direct), (Friedewald), (Martin-Hopkins), and (NIH Equation)

Measured directly, or calculated by each equation.

Capillary Blood Glucose and Interstitial Fluid Glucose

A fingerstick meter’s reading, or a continuous glucose monitor’s.

Every value also says where it came from (typed in, imported, or calculated) and which device measured it.

Private by Construction

One account is one person, and the database itself enforces it.

  • Only You Can Read It

    Row-level security limits every table to its owner, so no request reaches another person’s rows, whatever the app asks for.

  • Files Stay on Your Device

    Imports are read on your device, and only the rows they hold are saved. The file itself is never uploaded.

  • No Ads, No Analytics

    The app has no ads, trackers, or analytics, and your data is never sold.

  • Yours to Take

    Export everything as CSV files, free, at any time, or delete your account and every row with it.

Bring What You Already Have

Years of history arrive as the files these services let you download. Each is read on your device, even a multi-gigabyte Apple Health export, and importing a newer file updates what you have instead of duplicating it.

Vitals, sleep with its stages, workouts, steps, nutrition, cycle data, ECGs, audiograms, and more, from your iPhone’s export

Body composition, blood pressure, and more, from your Withings data export

Foods eaten, with their nutrients

CO₂, temperature, humidity, and air pressure from the Aranet Home app’s export

Transactions from your bank’s CSV files, in any layout

Events from any calendar that exports iCalendar (.ics), repeats included

Your location history, from Timeline’s export

Where and when each photo was taken, read on your device: the photos themselves are never uploaded

Free for What You Do

Logging, every import, full history, charts, habits, reference ranges, comparing metrics, the timeline, export, and one live connection are free. Kaizora Plus, coming at launch, adds Discover, the AI Overview, and unlimited live connections. Nothing free will ever move behind Plus.
