This is DOA not because there is anything wrong with the app, but because iDevices make objectively poor baby monitors.
Babies sleep a lot. A LOT. Any halfway decent baby monitor needs the ability to see in the dark (IR illumination) which iDevices don't have, so unless it's relegated to monitoring play areas during the day, its usefulness is limited. That doesn't mean the software isn't well designed, the hardware is simply not fit for purpose.
