I just uploaded a new version of Asthma Tracker & Log to the Android Marketplace. In this version you can now (optionally) mark your Peak Flow entries as pre- or post-medication. I also added a new chart to show the comparison so you can see how your medication is helping!
This idea came from a user of Asthma Track & Log, so please, if you have an idea you'd like to see incorporated please let me know! I have a couple more user ideas that I'll hopefully be adding soon.
The update will be available via Amazon soon as well.
