# Pi vs Brain Math

The clearest difference is review sentiment: Pi at 89% against Brain Math's 33%. Pi also leads on rating (4.7 vs 4.1) and ads (none vs shown). Brain Math's advantage is in-app purchases (none vs 6). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Pi sells 6 in-app purchases, starting at $3.99 per year. Brain Math asks for nothing beyond the download.
