# Knowre Math vs Crucible

The clearest difference is rating: Crucible at 5.0 against Knowre Math's 3.2. Crucible also leads on device support (3 vs 1). Knowre Math's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Crucible holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Knowre Math has 6 ratings behind it against 1, so its average is the more settled of the two.
