Pain logger

For those of us with chronic pain, the fewer barriers to accurate pain tracking the better. The ability to directly input pain scores on their watch would make it simple and easy for sufferers to collect data which could inform healthcare professionals or offer insights into trends or correlations.

I have seen discussions elsewhere on the internet about this type of app, so there is interest, but it does not yet seem to exist. 

I envisage an app in which: 

- User can choose times per day to track pain score

- Watch alerts user at each time, and prompts to enter a score 0-10

- Scores are saved and exportable. 

Extras that would be useful:

-Plot vs time

-Plot along with stress

Many thanks to anyone willing to have a go.
