Bubble Level holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 29% of Bubble Level's written reviews are positive against 36% of Level Tool's, so the app with the better star average is not the one people write more warmly about.
Bubble Level ships an update every 10 months, Level Tool monthly. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
