# HeatMap vs AI+ Bubble

The clearest difference is rating: HeatMap at 4.9 against AI+ Bubble's 3.0. HeatMap also leads on review sentiment (83% vs 50%) and update cadence (fortnightly vs every 9 months). AI+ Bubble's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. HeatMap sells 3 in-app purchases, starting at $4.49 per month. AI+ Bubble asks for nothing beyond the download.

HeatMap holds the better App Store score, 4.9 against 3.0.
