# Mad Math vs Hologram

The clearest difference is rating: Mad Math at 3.5 against Hologram's 2.0. Hologram's advantage is in-app purchases (none vs 5) and review sentiment (100% vs 91%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Mad Math sells 5 one-off in-app purchases. Hologram asks for nothing beyond the download.

Mad Math holds the better App Store score, 3.5 against 2.0. Both are backed by a comparable volume of ratings — 14 and 9 respectively. Written reviews complicate that: 91% of Mad Math's written reviews are positive against 100% of Hologram's, so the app with the better star average is not the one people write more warmly about.

Mad Math ships an update every 2 months, Hologram every 3 months. Both last shipped on November 2, 2026.
