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. A 7-day trial (card required, $0 due today) gets you the whole thing, or walk the no-card demo first.
