The most helpful feature about this app was how easy it made setting up remote connections when I needed to debug an issue with our application from another place in the world (we are working remotely). It does take time getting used to because there isn't much tutorial information but if you use things like Google Hangouts or Slack instead of relying solely through email communication then those features won't be so difficult. Try using them! We were able to successfully test out applications created locally without having any issues at all - just make sure everything's setup right before connecting your phone/tablet to each computer via wifi connection once installed. Gap Debugger is pretty straight forward to use and has most of the features I need. Only minor issue is having to do with memory management since it doesn't have ARC support. Otherwise I haven't found anything not to like so far. This is a good way to debug your app before making changes to make sure you are doing what you think you are. I've been able to use gap debugger to pinpoint exactly which line of code was causing my issues.
