What our participants say about the app

The app was brilliant! So easy and user friendly, not a problem at all. The chat function was also good and kept me informed when I had questions.
My experience with Field Notes was great. Very easy to use and seemed to push through without any problems.
The app is incredibly easy to use, and I wouldn’t say I’m tech savvy! The fact that everything’s so simple makes it fun and enjoyable to complete the tasks… if I was asked to use it again, I would happily agree!
