Official product pageOverview
The ApoloSign 21.5" Digital Calendar steps up to a bigger 1080p touchscreen for households that want the family schedule readable from across the kitchen. It carries the same dual-mode design as the rest of the lineup — a dedicated Family Calendar mode that auto-syncs Apple, Google, and Outlook calendars, plus a customizable Android dashboard mode with widgets, chore/reward tracking, meal planning, a family message board, and Google Photos integration, all without a subscription. Unlike the 15.6-inch model, this size ships wall-mount only, with no desk stand included.
Pros
- Bigger 21.5-inch screen is easier to read from across a room than the 15.6-inch model
- Same subscription-free calendar sync, chore tracking, and Google Photos integration as the rest of the lineup
- Anti-glare matte glass finish helps in kitchens with overhead lighting
- Google Assistant and Google Home smart-home integration built in
Cons
- Wall-mount only — no desk stand included, unlike the 15.6-inch model
- Still 1080p at this larger size, so pixel density is lower than the 15.6-inch version
- 4GB RAM / 64GB storage is the same as the smaller, cheaper model
