π in π
Today is already
hidden inside π.
π never ends and never repeats. Somewhere in its endless digits, today's date is waiting. Inpi finds it — and puts it on your Home Screen.

Today, June 16, 2026, appears here in π.
One widget. One quiet purpose.
Not a calculator. Not a study tool. A tiny daily delight.
A coincidence, every day
Each morning your date surfaces somewhere new in π. A small reminder that today is one of a kind.
Three sizes, three moods
Small, medium, and large widgets — from a single position to a full strip of surrounding digits.
Completely offline
A billion digits of π travel with the app. No network, no servers, nothing to wait for.
Made to disappear
No account, no notifications, no noise. It simply lives on your screen and refreshes at midnight.
How it works
- 1
Today becomes a number
Your date turns into eight digits, like 20260615.
- 2
We search a billion digits
Everything is precomputed — the first appearance of every date in π.
- 3
It lands on your screen
At midnight the widget refreshes, revealing where today hides in π.
“Mathematicians believe any sequence of digits — including today's date — eventually appears somewhere inside π.”
The quiet idea behind Inpi
Nothing leaves your device
- No data collected
- No network access — the digits of π are bundled offline
- No account, tracking, or third-party SDKs
