Verdict

The call

The clearest difference is rating: Flat at 4.6 against MIDI Score's 4.0. Flat also leads on ads (none vs shown) and review sentiment (68% vs 43%). MIDI Score's advantage is device support (4 vs 2) and iOS requirement (9.0 vs 16.4). On price, in-app purchases and monetization model there is nothing between them.
