Verdict

The call

The clearest difference is ads: IMSLP at none against Musicnotes's shown. IMSLP also leads on review sentiment (70% vs 55%) and update cadence (every 10 days vs every 3 weeks). Musicnotes's advantage is ratings volume (43K vs 507) and rating (4.8 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Musicnotes sells 12 in-app purchases, starting at $14.99 per year and IMSLP sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Musicnotes holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Musicnotes has 43K ratings behind it against 507, so its average is the more settled of the two. Written reviews complicate that: 55% of Musicnotes's written reviews are positive against 70% of IMSLP's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Musicnotes ships an update every 3 weeks, IMSLP every 10 days. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
