# Fast Math vs Mental Arithmetic Math

The clearest difference is rating: Fast Math at 5.0 against Mental Arithmetic Math's 4.4. Fast Math also leads on ads (none vs shown). Mental Arithmetic Math's advantage is in-app purchases (none vs 6) and review sentiment (90% vs 67%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Fast Math sells 6 one-off in-app purchases. Mental Arithmetic Math asks for nothing beyond the download.

Fast Math holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Mental Arithmetic Math has 90 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Fast Math's written reviews are positive against 90% of Mental Arithmetic Math's, so the app with the better star average is not the one people write more warmly about.

Fast Math ships an update every 4 months, Mental Arithmetic Math every 2 months. Both last shipped on September 18, 2026.
