ReceptionRating · Positive reviews · Number of ratings

Bubble Level Tool holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: Bubble Level Tool has 2.5K ratings behind it against 163, so its average is the more settled of the two. Written reviews complicate that: 57% of TiltMeter's written reviews are positive against 6% of Bubble Level Tool's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TiltMeter ships an update every 2 weeks, Bubble Level Tool weekly. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
