ReceptionRating · Positive reviews · Number of ratings

Molekule holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Molekule has 12K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 17% of Molekule's written reviews are positive against 30% of Rabbit Air 2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Molekule ships an update every 2 months, Rabbit Air 2 every 6 weeks. The most recent releases landed on November 3, 2026 and October 27, 2026 respectively.
