I love the reporting functions of Withings, specifically the monthly report with all the areas being tracked (steps, sleep, BP, body temp, weight). My wife suffers from migraines and we are trying to determine triggers. It would be great if we had a way to track additional things like that in this app and have it display in that monthly heatmap. I know migraines may be a niche market, so maybe you could just add the ability to track what ever misc items the user wanted. This would be very helpful when trying to see patters or find triggers that cause a condition like migraines.
