Platforms and Media

Epicollect5 mobile app is available for Android and iOS.


We support phones and tablets on Android 5.1 and onwards. However, starting with Android 5.0, the webview was moved to a separate application that can be updated independently of Android.

This means that most Android 5.0+ devices are going to be running a modern version of Chromium.

However, there is still a subset of Android devices that are unable to have their webview updated.

These webviews are typically stuck at the available version when the device initially shipped, making Epicollect5 incompatible.

Download it from the Play Store. If Epicollect5 does not work for you and it gets stuck at the splash screen, you can try to update Chrome and the WebView as explained at this link.

You could also try to install an older version from this link.


We support iPhones and iPads with iOS 14+.

Download it from the App Store.

Media files


Photos taken/imported to Epicollect5 will be resized to a resolution of 1024 x 768 px (landscape or portrait, aspect ratio 4:3).

We found this size to be reasonable for data collection purposes, it is stable across devices with low memory/specs and easily viewable via the web application. Due to modern devices taking pictures at crazy resolutions and with file sizes up to 20MB we had to come up with a consistent solution.

If you want the original, full-size image we recommend taking the photos outside of Epicollect5, then importing them in Epicollect5 using the image picker when adding an entry. That way the original photo is saved in the device gallery app.

As a side note, the popular app Instagram does use a similar approach.

As technology evolves, we might raise the resolution limits at some point in the future.


Audio files are stored as.mp4 on Android and .wav on iOS.

They are coded as AAC with 44100hz audio sampling.

Max file size is 100MB.


Video files are stored as .mp4 files, coded as h.264 on iOS, and on Android it depends on the platform and device, but it is sent always as a mp4 file.

Max file size is 500MB.
