ReceptionRating · Positive reviews · Number of ratings

LiveDoodle holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Algodoo has 878 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 59% of Algodoo's written reviews are positive against 50% of LiveDoodle's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Algodoo ships an update monthly, LiveDoodle every 4 months. The most recent releases landed on October 16, 2026 and October 4, 2026 respectively.
