An iPhone app that estimates crowd size as a range and produces a documented PDF report.

Landing page captured for the 2026-10-19 issue.

For: Event organizers and people documenting crowd sizes
Worth noticing: The site gives different stated margins by mode: ±12% above 500 people in Direct, and ±20% for the long-duration Parade mode.

Field notes

The homepage distinguishes live viewing, a panoramic sweep and a fixed-camera procession count, with different stated error margins for each. It says the procession mode records counts by minute and marks intervals when movement or an obstructed image makes counting unusable. Reports can include GPS position and viewing direction; the site says captured heads and nearby faces are anonymized by default.
