# IMSA vs Marbles

The clearest difference is ads: Marbles at none against IMSA's shown. Marbles also leads on update cadence (weekly vs every 2 months) and rating (4.3 vs 4.1). IMSA's advantage is ratings volume (70 vs 3). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Marbles holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: IMSA has 70 ratings behind it against 3, so its average is the more settled of the two.

IMSA ships an update every 2 months, Marbles weekly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
