Verdict
The clearest difference is rating: Highlights at 4.5 against Mach Note's 3.0. Highlights also leads on update cadence (fortnightly vs every 9 months) and ratings volume (1.6K vs 2). Mach Note's advantage is monetization model (free vs freemium). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mach Note sells 1 one-off in-app purchase and Highlights sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Highlights holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Highlights has 1.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of Mach Note's written reviews are positive against 53% of Highlights's.
Mach Note ships an update every 9 months, Highlights fortnightly. The most recent releases landed on October 5, 2026 and October 18, 2026 respectively.
