# The Marbl Platform vs D2DX

The clearest difference is review sentiment: The Marbl Platform at 100% against D2DX's 33%. The Marbl Platform also leads on iOS requirement (11.0 vs 14.0.0). D2DX's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

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

D2DX holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 100% of The Marbl Platform's written reviews are positive against 33% of D2DX's, so the app with the better star average is not the one people write more warmly about.

The Marbl Platform ships an update every 5 weeks, D2DX every 3 weeks. The most recent releases landed on June 5, 2026 and September 8, 2026 respectively.
