# Attack Drums vs Piano Chords Compass

The clearest difference is review sentiment: Piano Chords Compass at 78% against Attack Drums's 34%. Piano Chords Compass also leads on price ($5.99 vs $14.99) and device support (4 vs 1). Attack Drums's advantage is rating (4.4 vs 2.3) and ratings volume (23 vs 3). On ads, in-app purchases and monetization model there is nothing between them.

Attack Drums costs $14.99 and Piano Chords Compass $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Attack Drums holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: Attack Drums has 23 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 34% of Attack Drums's written reviews are positive against 78% of Piano Chords Compass's, so the app with the better star average is not the one people write more warmly about.
