Verdict
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.

Both are free to download. MIDI Score sells 1 one-off in-app purchase and Flat sells 10 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Flat holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Flat has 7.1K ratings behind it against 151, so its average is the more settled of the two. Written reviews point the same way: 43% of MIDI Score's written reviews are positive against 68% of Flat's.
MIDI Score ships an update every 2 months, Flat fortnightly. The most recent releases landed on November 6, 2026 and November 12, 2026 respectively.
