# IMSLP vs CueFlip

The clearest difference is rating: CueFlip at 5.0 against IMSLP's 4.6. CueFlip also leads on review sentiment (100% vs 70%). IMSLP's advantage is ratings volume (513 vs 1) and iOS requirement (13.0 vs 16.4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. IMSLP sells 1 in-app purchase, starting at $3.99 per month and CueFlip sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

CueFlip holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: IMSLP has 513 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 70% of IMSLP's written reviews are positive against 100% of CueFlip's.

IMSLP ships an update every 10 days, CueFlip fortnightly. Both last shipped on October 25, 2026.
