Skylight and Hearth make lovely dedicated touchscreens; Cozi is a beloved free app. We say what each does well below, by name. The short version: they sell you a screen (or live on your phone). Cornerstone turns a screen you already own — an old iPad, a wall TV, a spare laptop — into the same family command center, for $0 hardware, and adds JQ (your family’s AI assistant), an intercom, wake-to-a-parent’s-voice alarms, and sleep stories. Where we’re behind (no dedicated hardware, photo frame still coming), the table says so.
