# MathTappers vs Inference Ace

The clearest difference is update cadence: Inference Ace at every 7 months against MathTappers's every 33 months. MathTappers's advantage is ratings volume (140 vs 21). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. MathTappers sells 2 one-off in-app purchases and Inference Ace sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: MathTappers has 140 ratings behind it against 21, so its average is the more settled of the two.
