# PianoStream vs DiskPiano

The clearest difference is monetization model: DiskPiano at free with in-app purchases against PianoStream's subscription. DiskPiano also leads on update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.8). PianoStream's advantage is ratings volume (210 vs 10) and chart position (#129 vs unranked). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. PianoStream sells 6 in-app purchases, starting at $9.99 per 7 days and DiskPiano sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

DiskPiano holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PianoStream has 210 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 94% of PianoStream's written reviews are positive against 100% of DiskPiano's.

PianoStream ships an update every 2 months, DiskPiano every 4 days. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
