The UI is simple, easy to use without any coding knowledge required. It allows you add multiple geofences at once which makes it easier for us as marketers who are not technical people but want our app's users be able to find out more about what's around them using their GPS or Wifi device. We also used this api service when testing an android version of our application back then. I think we were running into some issues with the Android OS because Google had just started putting restrictions where even if there was no problem before it could still throw up errors such as java process not found etc. This made us unable to test properly so therefore ended up delaying the release date by weeks (we were originally aiming towards October).
