Seems like we should be able to do this by referring to the navigator variable (navigator.userAgent). See, e.g.,

Or navigator.platform, perhaps: https://stackoverflow.com/questions/9038625/detect-if-device-is-ios

Seconding your suggestion for using navigator.userAgent based on this tutorial.

Trying to give some thought as to why we want this info. I can think of two immediate reasons:

1. Debugging: If our task fails with a participant, knowing their set up will make it easier to debug.
2. Exclusion: If we want to exclude mobile users.

The first motivation merely requires logging the information. The second motivation requires doing something with the info. It seems detecting a mobile user is doable but nontrivial, and requires periodic updating of regex.

Another potential solution, as suggested here, is simply logging the size of the screen and preventing users from advancing until their screen has reasonable dimensions.

In any event, implementing (1) seems reasonable.

Recording user platform/device with ad6bdc4.

Turns out Flask includes platform/browser detection. Will work on excluding mobile users with next push.
