Kizashi — Signs for You
Patterns that hold for you
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Your body writes something down each day. Kizashi finds the patterns hidden there — entirely on your device.
Kizashi finds the patterns that hold true only for you — with zero data entry.
It quietly reads the records already on your iPhone — sleep, heart rate, steps, weather, your schedule — entirely on this device, and looks for correlations that are true for you. You never have to log anything.
- Discover
From the past year of your records, Kizashi surfaces statistically credible correlations, each with a confidence level. "This is a correlation. Whether it is the cause, we cannot yet say." Kizashi says plainly what it does not know.
- Test
For a sign that interests you, run a small ABAB self-test (n-of-1) and check it for yourself. Did it work, or was there no difference? Quietly, honestly.
- Everything stays on your device
All analysis happens on your iPhone. There are no servers. Your records never leave the device.
- What Kizashi does not do
* No scoring. No scores, no goals, no lectures.
* No nagging. It is not an app to open every day.
* No diagnosis. Kizashi is not a medical device; what it finds are correlations, not medical advice.
You can export a summary to bring to a conversation with a healthcare professional.
Pricing: Free to use. All signs and the weeks ahead are available via a monthly or yearly plan, or a one-time purchase.
