Official product pageOverview
The ApoloSign 27" 4K Digital Calendar is the top-of-line model in the calendar series, pairing the largest screen size with a 3840×2160 4K panel and an anti-glare matte finish. It runs the same dual-mode design as the rest of the lineup — a Family Calendar mode syncing Google, Apple/iCloud, Outlook, Yahoo, and Cozi calendars, and an Android dashboard mode with chore/reward tracking, meal planning, a family message board, Google Photos integration, and voice control through Google Assistant with Gemini AI — all with no subscription fee.
