# AI+ Bubble vs Bubble Index

The clearest difference is review sentiment: AI+ Bubble at 50% against Bubble Index's 0%. AI+ Bubble also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.4). Bubble Index's advantage is rating (4.6 vs 3.0) and update cadence (every 2 months vs every 9 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Bubble Index holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Bubble Index has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of AI+ Bubble's written reviews are positive against 0% of Bubble Index's, so the app with the better star average is not the one people write more warmly about.

AI+ Bubble ships an update every 9 months, Bubble Index every 2 months. The most recent releases landed on September 14, 2026 and July 17, 2026 respectively.
