A complete, verified reference of the first million decimal digits of pi — free to browse in full. A search tool is also available below if you're looking for a specific sequence.
Pi (π) is the ratio of every circle's circumference to its diameter — an ancient, endless constant mathematicians have chased since Archimedes bounded it by hand over 2,200 years ago. The computer era began in 1949, when the ENIAC calculated π to 2,037 digits in 70 hours; the current record, set in November 2025 by StorageReview and Micron Technology, stands at 314 trillion digits.
Additional feature: search the full 1,000,000-digit dataset for any sequence
Look up any 4-digit account code to see its activation code and status, and reset it if a customer lost theirs or it failed to register — this frees the code to be activated again.

This is what loads in automatically every time you log in with this code — it stays set until you change it below and hit Save.
These settings belong to your peek screen itself, not any one mode — they stay exactly as saved no matter which mode above is active or how you switch between them.
A default background is already applied — replace it with your own anytime. If you use a home screen screenshot, crop out the top status bar (time, signal, battery) first using the Photos app's edit/crop tool, so it sits correctly behind the real status bar instead of showing a duplicate.

Each search a spectator makes uses the next group below, in order. A 5th search onward behaves as a normal real search. Position 1 in each group is required — 2–4 are optional. The string box replaces whatever comes after the searched digits, both in the preview and in the database. Use X to repeat, Y to repeat reversed — see below.

Shorthand: X repeats what came before it; Y repeats it reversed. 1234X → 12341234 ·

The real, unmodified digits of pi stay exactly as they are — nothing is forced. Every digit typed into the search box is mirrored to your peek screen live, before Search is even pressed. Hitting Search additionally reveals the genuine continuing digits across the top strip.
Build a sequence of blocks — one per spectator search. Normal, Real, and Birthday can repeat as many times as you like; each of the 4 Force searches can only be used once per workflow. Once the spectator searches past the last block, every search after that behaves as Normal.

Modes
None (Idle)
Nothing is active. Searches behave exactly like the ordinary public site — nothing forced, nothing sent anywhere.
Force Mode
Whatever a spectator types, the result shown is one you've set in advance — a real position in pi with your own text planted after it. You configure up to 4 searches in a row, each with its own forced position.
Real Mode
Nothing is forced — the real, genuine digits of pi are searched. But every digit typed, and the position it's found at, is quietly sent to your Peek Screen live as they type.
Workflow
Chain several steps together for a full routine — mix Force, Real, Birthday, and Normal blocks in any order. Each spectator search moves to the next block automatically.
Your Peek Screen
Your Peek Screen is a private, black screen only you look at — it's where forced/real results and phase info show up live as a spectator searches. It lives at:
onemilliondigits.com/XXXX
Open that on a second device and keep it out of sight. In Settings you can also add a custom background image to your Peek Screen, and choose whether it launches as a plain black screen or disguised as a Notes app.
Customize Layout

Tap a field below to drop it onto your image, then drag it into place. Tap a placed field to remove it. This replaces the default peek text with your own layout on this background.
About this site
onemilliondigits.com presents the first one million decimal digits of π as an entertainment reference. The full dataset is free to browse in the digit viewer above.
As an additional feature, you can search the dataset for any sequence of digits — a birthday, an old phone number, anything you'd like to check for. Enter a string of digits above and we'll show you where it first appears, along with the surrounding digits for context.
