Right there with you! I purchased the Fi tracker and feel the same reassurance you do - our pets are like our children so I totally get it that peace of mind. We are very active as well and the phone alerts that say things like, "Ethel is a Rock Star," or "Wow! 20 days in a row she's met her goal!" and such are hysterical. I find myself bummed on rainy days when she breaks her streak, which is a feature I thought was frivolous at first but now I'm in it. While Fi has the same features but I regret that I didn't go with the Whistle because I would have preferred keeping my own collars. Wishing you happy trails!
