TL;DR: A HomeKit-supported camera monitor with multiple live cameras on one screen for iOS, watchOS and tvOS. Only $4.99 on the App Store.
HomeCam is the only app that allows the user to monitor multiple live feeds from their HomeKit-supported cameras on one screen simultaneously.
Apple's Home app shows snapshots of camera feeds until you open a camera feed to full screen, HomeCam works around this limitation allowing you to easily monitor what your camera is seeing in realtime.
