# Pi vs Math IQ Test + Brain Training

The clearest difference is rating: Pi at 4.7 against Math IQ Test + Brain Training's 4.1. Pi also leads on ratings volume (1.7K vs 12). Math IQ Test + Brain Training's advantage is update cadence (weekly vs every 3 months) and monetization model (free vs free with in-app purchases).

Both are free to download. Pi sells 6 in-app purchases, starting at $3.99 per year and Math IQ Test + Brain Training sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Pi holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Pi has 1.7K ratings behind it against 12, so its average is the more settled of the two.
