# Bubble Level vs Bubble Level + Spirit Level

The clearest difference is review sentiment: Bubble Level + Spirit Level at 100% against Bubble Level's 29%. Bubble Level + Spirit Level also leads on update cadence (fortnightly vs every 10 months). Bubble Level's advantage is ratings volume (3.1K vs 35) and rating (4.6 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bubble Level sells 1 one-off in-app purchase and Bubble Level + Spirit Level sells 7 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Bubble Level has 3.1K ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 29% of Bubble Level'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.

Bubble Level ships an update every 10 months, Bubble Level + Spirit Level fortnightly. The most recent releases landed on November 1, 2026 and October 25, 2026 respectively.
