Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
ChordMapMidi costs $3.99 and Fortamento $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ChordMapMidi holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Fortamento has 110 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 53% of ChordMapMidi's written reviews are positive against 89% of Fortamento's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 8 months. The most recent releases landed on September 22, 2026 and October 11, 2026 respectively.
