I be been using this app for 3 days, and even though my work wifi blocks the camera, the developer emailed me and told me how to set up noise and motion alerts, so I could be notified when something happened without keeping the parent unit up, so it saves me on my data charges! Works like a charm! Using to check that my dog sitter is really coming to let the dogs out and what times. Its also very nice to be able to check in at any moment and see my pups and using no new hardware, just an old iPhone I had laying around! Being able to talk to them and play music is just the icing on the cake on top of that! Best $3.99 I ever spent!
