I have a few suggestions to improve the app for those of us who have unique challenges.
I'm totally blind which makes me unable to complete the alertness checker. I'd like to be ableto provide the study with a full set of data. One possible option is something I saw in a mindfulness app. Every time the phone vibrates, you touch the screen. It would be a good option for those who would prefer the tactile prompt.
On a different note, it might also be useful to add a question about the current pain level to the check ins, average overall during the day and night.
