Verdict

The call

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.
