Verdict

The call

The clearest difference is monetization model: Bubble Level at free with in-app purchases against ToolBox's subscription. ToolBox's advantage is ads (none vs shown) and update cadence (every 9 days vs every 2 months). On price, rating, review sentiment and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. ToolBox sells 6 in-app purchases, starting at $0.99 per month and Bubble Level sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Bubble Level holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: ToolBox has 1K ratings behind it against 61, so its average is the more settled of the two. Written reviews complicate that: 32% of ToolBox's written reviews are positive against 25% of Bubble Level's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ToolBox ships an update every 9 days, Bubble Level every 2 months. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
