# Smart Tools vs Bubble Level

The clearest difference is ads: Bubble Level at none against Smart Tools's shown. Bubble Level also leads on update cadence (every 2 weeks vs every 3 months) and rating (4.9 vs 4.5). Smart Tools's advantage is ratings volume (314 vs 10) and iOS requirement (11.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Smart Tools sells 1 one-off in-app purchase and Bubble Level sells 5 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Bubble Level holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Smart Tools has 314 ratings behind it against 10, so its average is the more settled of the two.

Smart Tools ships an update every 3 months, Bubble Level every 2 weeks. The most recent releases landed on September 19, 2026 and September 18, 2026 respectively.
