ReceptionRating · Positive reviews · Number of ratings

Bubble Level for iPhone holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Bubble Level for iPhone has 112K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 35% of Bubble Level for iPhone's written reviews are positive against 100% of Bubble Level + Spirit Level's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bubble Level for iPhone ships an update every 5 weeks, Bubble Level + Spirit Level every 3 weeks. The most recent releases landed on September 28, 2026 and September 22, 2026 respectively.
