# IMO vs kMath

The clearest difference is ratings volume: IMO at 175 against kMath's 6. IMO also leads on iOS requirement (9.0 vs 13.0). kMath's advantage is review sentiment (71% vs 57%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. IMO sells 1 one-off in-app purchase and kMath sells 1 in-app purchase, starting at $14.99 per 3 months. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.2 for IMO against 4.3 for kMath. That said, the two scores are not equally well evidenced: IMO has 175 ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 57% of IMO's written reviews are positive against 71% of kMath's.
