Bubble Level holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 40, so its average is the more settled of the two. Written reviews complicate that: 43% of RIDGID Level's written reviews are positive against 29% of Bubble Level's, so the app with the better star average is not the one people write more warmly about.
RIDGID Level ships an update every 13 months, Bubble Level every 10 months. The most recent releases landed on October 14, 2026 and October 17, 2026 respectively.
