Questions you ask at 3 a.m.
Does the screen have to stay on?+
Yes, on the device near your baby. Mobile browsers can suspend the microphone when a phone locks or the app goes to the background, and iPhones are especially strict about it. Babyphone keeps the screen active and shows it as solid black. Keep the device plugged in.
What happens if the connection drops?+
Babyphone reconnects on its own. If the sound doesn't come back after a few seconds, an alarm rings on your phone.
Do alerts work when the app is closed?+
No. Babyphone has to stay open on your phone for you to receive sound and alerts.
Do I need to install anything?+
No, everything runs in the browser. On iPhone, add it to your Home Screen to receive notifications.
How reliable is cry detection?+
It analyzes the sound to spot crying, and you can tune its sensitivity to the room. It's an aid: it can be wrong, and it doesn't replace an adult being there.
