# Mathway vs Calculate84

Mathway and Calculate84 both sit at 4.9 stars, but that hides the real split: 74% of Calculate84's written reviews are positive against 51% of Mathway's. Mathway's advantage is ratings volume (425K vs 53K). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Mathway sells 8 in-app purchases, starting at $9.99 per month and Calculate84 sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Mathway against 4.8 for Calculate84. That said, the two scores are not equally well evidenced: Mathway has 425K ratings behind it against 53K, so its average is the more settled of the two. Written reviews are what separate them: 51% of Mathway's written reviews are positive against 74% of Calculate84's.
