Verdict

The call

The clearest difference is in-app purchases: MobileSheetsLite at none against IMSLP's 1. MobileSheetsLite also leads on review sentiment (80% vs 70%). IMSLP's advantage is ratings volume (507 vs 7) and iOS requirement (13.0 vs 15.0). On price, rating, update cadence and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

IMSLP holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: IMSLP has 507 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 70% of IMSLP's written reviews are positive against 80% of MobileSheetsLite's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

IMSLP ships an update every 10 days, MobileSheetsLite weekly. The most recent releases landed on October 16, 2026 and October 3, 2026 respectively.
