There's another app called Pokedetector which will send phone notifications when pokemon are near by so you don't have to walk around with your phone out (especially usefully if you have a smart watch). It's kind of neat if you want something low-powered running the background as you're going about your day. App developers recommend using a seperate account incase it goes against the TOS. It'll notify of the random spawns (common for all players), but not lures and incenses. Also not sure if it'll help with egg hatching.
