PitPat is the fun and simple way to find out. PitPat attaches securely to your dogs collar, and is lightweight, safe and comfortable for your dog to wear. The PitPat iOS and Android app recommends daily exercise goals based on breed (over 200 to choose from), age and weight. See how long your dog walks, runs, plays and rests every day, and how many calories they've burnt. Keep track of your progress, and try to reach your goal every day. No monthly subscription fees, and no battery recharging needed. Battery life up to one year. PitPat works with iOS and Android phones using Bluetooth 4.0 (also called Bluetooth Smart or Bluetooth Low Energy).
