ODK lets you build powerful forms to collect the data you need wherever it is. Here are three reasons why leading researchers, field teams, and other professionals use ODK to collect data that matters. 1. Build powerful forms with photos, GPS locations, skip logic, calculations, external datasets, multiple languages, repeating elements, and more. 2. Collect data online or 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. Get started at https://getodk.org
