# Bubble Level vs Inclinometer

The clearest difference is rating: Bubble Level at 4.5 against Inclinometer's 2.0. Bubble Level also leads on ratings volume (719 vs 12) and update cadence (weekly vs every 3 weeks). Inclinometer's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Bubble Level sells 11 in-app purchases, starting at $1.99 per 7 days and Inclinometer sells 4 in-app purchases, starting at $1.49 per 2 months. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: Bubble Level has 719 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 41% of Bubble Level's written reviews are positive against 27% of Inclinometer's.

Bubble Level ships an update weekly, Inclinometer every 3 weeks. Both last shipped on October 24, 2026.
