great device but app is little bit buggy

I was thinking to have my personal ECG recorder for long time, I was about to build one, I have arrhythmia and wanted to see myself before I go to doctor. This thing is awesome, I use it on my chest instead of holding in my hands, that way the ECG is very clean, since the device apparently doesnt have filters to filter 50 Herz noise. The placement is very important, I tried different positions and the best is right on top of the heart in the center of the chest horizontally, that way I could see all the waves. If only the app had more detailed analysis, like giving me QT interval and other important numbers. What I get from analysis is only Normal or Abnormal. Also the app sometimes hangs and requires hard reboot of my iPhone 5. The time stamp on ECG recording is also wrong, about seven hours back (?), was it coded in Russia? It should use current time of the iPhone location, in my case EST, so if I send the ECG to my doctor, he could get wrong impression of the time of event.
