Needs more description on How to Use

It allowed me to calculate distance using driving method for my first calculation. Then, I couldnt figure out how to start a brand new calculation without using the same starting point as my first one. It wanted to find my location. Then, once it secured my location, it lost the ability to calculate using the driving method, giving me a straight line distance instead, which is useless. It crashed about 3 times while I was trying to figure out how to use it. It invokes Google maps and/or Evernote if theyre on your device, but Im not sure why. No explanation or guide makes this app extremely hard (impossible) to use. I ended up simply deleting it.
