# Acute Calculator vs KAALM

The clearest difference is in-app purchases: KAALM at none against Acute Calculator's 3. Acute Calculator's advantage is ratings volume (116 vs 4). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Acute Calculator sells 3 one-off in-app purchases. KAALM asks for nothing beyond the download.

Acute Calculator holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: Acute Calculator has 116 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 95% of Acute Calculator's written reviews are positive against 100% of KAALM's, so the app with the better star average is not the one people write more warmly about.
