About this app

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.

I'm so sorry you are having errors in uploading. Unfortunately, only the person who setup the server and asked you to collect data can solve this problem. Please contact them, and if they can't solve it, ask them to email us at support@getodk.org.

This is a very good app, user friendly can manage your form easily on the project settings. I like the new features where by one can have run different projects on the same application with interference. Last this app is good when it comes to adds, no interference at all and can work offline & switch data when connecting to your server. Thumbs up for the improvements.

As for the opensource free app, I'm pretty much satisfied with the result. However, one bug, when i switch the app language from english to burmese language, all the downloading forms and uploading responses no longer working. When i switch back to english, it works again. Please kindly investigate the issue. This bug has been long there for years.
