Verdict

The call

The clearest difference is monetization model: MIDI Score at free with in-app purchases against Composer Pro's subscription. MIDI Score also leads on iOS requirement (9.0 vs 15.0). Composer Pro's advantage is rating (4.5 vs 4.0) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.
