In my opinion, what is more useful and important, is your historical charting with the app or any other app. A one of doesn't really mean much compared to the former. If you see the trend stay around where it is today, follow-up with your doctor.
The other app mentioned in comments is for charting actual reports you can email or print, which you may want to consider.
I think apps like these are great for not just ourselves but our doctors as well, as it gives us a good historical timeline of events, which may help with any diagnosis.
