# Bubblepics vs Category Topic

The clearest difference is review sentiment: Bubblepics at 40% against Category Topic's 0%. Bubblepics also leads on in-app purchases (none vs 13). Category Topic's advantage is rating (5.0 vs 4.7). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Category Topic sells 13 one-off in-app purchases. Bubblepics asks for nothing beyond the download.

Category Topic holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 317 and 173 respectively. Written reviews complicate that: 40% of Bubblepics's written reviews are positive against 0% of Category Topic's, so the app with the better star average is not the one people write more warmly about.

Bubblepics ships an update weekly, Category Topic every 9 days. The most recent releases landed on October 30, 2026 and October 29, 2026 respectively.
