# MathTappers vs Main Idea

The clearest difference is rating: Main Idea at 3.7 against MathTappers's 3.1. MathTappers's advantage is monetization model (free vs free with in-app purchases) and review sentiment (67% vs 42%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. MathTappers sells 1 one-off in-app purchase and Main Idea sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Main Idea holds the better App Store score, 3.7 against 3.1. That said, the two scores are not equally well evidenced: MathTappers has 80 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of MathTappers's written reviews are positive against 42% of Main Idea's, so the app with the better star average is not the one people write more warmly about.

MathTappers ships an update every 33 months, Main Idea every 22 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
