text: Ken: Do you use endomondo?
  Martha: Yeah, everyday, you installed too? :)
  Ken: I did, I started running and wanted to track my progress
  Martha: And?
  Ken: It doesn't work properly I think or maybe there's something wrong with my phone.
  Ken: I went for a jog, turned it on and I'm sure I wasn't running for more than an hour. I checked it for my results and it was off
  Martha: Hm, weird...
  Ken: I know, I wasn't using my phone at all, just had it with me while I was jogging
  Martha: Did you have any notification?
  Ken: No, the battery was almost depleted though
  Martha: Eh, it happens in certain models, unfortunately. It works fine with mine, but my friend had a similar issue. Maybe your phone's battery or processor, I don't really know, is too weak for it
  Ken: Maybe, but that's weird, it's just a fitness app
target: Ken has installed an app for running but it is not working properly on his phone.
