ChordPolyPad's advantage is review sentiment (92% vs 67%) and ratings volume (51 vs 3). On ads and device support there is nothing between them.

ChordPolyPad costs $17.99 and ChaosArp 2 $5.99 up front. ChordPolyPad sells 3 one-off in-app purchases. ChaosArp 2 asks for nothing beyond the download.

ChaosArp 2 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ChordPolyPad has 51 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 92% of ChordPolyPad's written reviews are positive against 67% of ChaosArp 2's, so the app with the better star average is not the one people write more warmly about.
