# Mental Math Games vs Pi

The clearest difference is in-app purchases: Pi at none against Mental Math Games's 7. Pi also leads on device support (3 vs 1) and iOS requirement (12.0 vs 26.0). Mental Math Games's advantage is ads (none vs shown) and ratings volume (1.2K vs 35). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Mental Math Games sells 7 in-app purchases, starting at $4.99 per month. Pi asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Mental Math Games against 4.9 for Pi. That said, the two scores are not equally well evidenced: Mental Math Games has 1.2K ratings behind it against 35, so its average is the more settled of the two. Written reviews are what separate them: 93% of Mental Math Games's written reviews are positive against 100% of Pi's.

Mental Math Games ships an update every 9 days, Pi every 10 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
