# Pi vs Pi

The clearest difference is review sentiment: Pi at 100% against Pi's 89%. On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pi sells 6 in-app purchases, starting at $3.99 per year and Pi sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
