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

2. Collect data offline with either the mobile app or the web app and synchronize that data when an Internet connection is found.

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