# Bubble Level Plus+ vs ToolBox

The clearest difference is monetization model: Bubble Level Plus+ at free with in-app purchases against ToolBox's subscription. Bubble Level Plus+ also leads on ratings volume (15K vs 1K). ToolBox's advantage is update cadence (every 9 days vs every 2 months) and iOS requirement (11.3 vs 17.6). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Bubble Level Plus+ sells 2 one-off in-app purchases and ToolBox sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Bubble Level Plus+ holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Bubble Level Plus+ has 15K ratings behind it against 1K, so its average is the more settled of the two. Written reviews point the same way: 38% of Bubble Level Plus+'s written reviews are positive against 32% of ToolBox's.

Bubble Level Plus+ ships an update every 2 months, ToolBox every 9 days. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
