Free church attendance tracker & rolling-average calculator
Paste your weekly attendance and get the average, the highest and lowest Sunday, and a rolling comparison of the last four weeks against the four before that. It runs entirely in this browser tab — nothing you type is sent anywhere or saved anywhere, so there is nothing to sign up for and nothing to clean up after.
A label is optional. Jan 4, 118 and a bare 118 both work. Nothing you type here is sent anywhere or saved — it lives in this browser tab only.
Why a rolling average, not just this Sunday
A single Sunday is noisy — weather, a holiday weekend, a big event elsewhere in town. A short rolling average smooths that out without waiting a whole year to see a trend. The full explanation, with worked examples covers how to read it and how big a swing is actually worth noticing.
This calculator is free forever and asks for nothing.
SundayBridge is a separate, paid product: it records attendance for you every week, charts it automatically, and keeps it attached to the people it's about. 30 days free gets you the whole thing, and we don't ask for a card to start.
