[ODK Collect and form audit logs](https://docs.getodk.org/collect-intro/)

## Use and fit

Android form capture supports offline work, photos, location, signatures and repeating records. An optional configured audit log can retain form-edit events. Fit: custom service records where a business can maintain its own forms and server.

## Cost and access

Collect is an open-source app; server hosting, form development and maintenance are additional work. No managed-cloud price verified.

## Popularity and evidence

GitHub showed 790 stars / 1.4k forks on 2026-09-18; the project reports billions of data points collected. These are not trade-user counts.
