STETSOM STX DSP holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: STETSOM STX DSP has 424 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 57% of DSI's written reviews are positive against 39% of STETSOM STX DSP's, so the app with the better star average is not the one people write more warmly about.
