ODK Collect

ODK lets you build powerful offline forms to collect the data you need wherever it is.

Here are six reasons why leading researchers, field teams, and M&E professionals chose ODK for their offline data collection.

1. Build powerful forms with photos, GPS locations, skip logic, calculations, external datasets, multiple languages, repeating elements, and more.

2. Collect data offline with either the mobile app or the web app. Forms and submissions are synced when a connection is found.

3. Analyze with ease by connecting apps like Excel, Power BI, Python, or R to create live-updating and shareable reports and dashboards.
