ReceptionRating · Positive reviews · Number of ratings

Explain Everything Whiteboard holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Explain Everything Whiteboard has 8.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Sphere2's written reviews are positive against 48% of Explain Everything Whiteboard's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sphere2 ships an update every 2 months, Explain Everything Whiteboard every 2 weeks. The most recent releases landed on June 11, 2026 and September 29, 2026 respectively.
