I’m looking for an Android app that will track pain levels and be able to export the data for outside analysis. I’m concerned that the apps have reports but I won’t be able to do my own analysis or combine with data from other sources…
What exactly are you recording? If it’s just a pain “rating” (e.g. 0-10) and a time (and perhaps a location), you could easily use a general-purpose tracking app that lets you export your data, e.g. Trackthisforme or TapLog.
