# Category Topic vs Association Cube

The clearest difference is rating: Category Topic at 5.0 against Association Cube's 3.0. Category Topic also leads on ratings volume (122 vs 2). Association Cube's advantage is chart position (#174 vs unranked) and iOS requirement (13.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Category Topic sells 13 one-off in-app purchases and Association Cube sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Category Topic holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Category Topic has 122 ratings behind it against 2, so its average is the more settled of the two.

Category Topic ships an update fortnightly, Association Cube every 2 weeks. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
