# Piano 3D vs Keyboard Instrument Simulator

Piano 3D and Keyboard Instrument Simulator both sit at 3.6 stars, but that hides the real split: 80% of Piano 3D's written reviews are positive against 13% of Keyboard Instrument Simulator's. Piano 3D also leads on monetization model (free with in-app purchases vs subscription) and ads (none vs shown). Keyboard Instrument Simulator's advantage is update cadence (every 3 weeks vs every 6 weeks) and ratings volume (81 vs 9). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Piano 3D sells 3 one-off in-app purchases and Keyboard Instrument Simulator sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 3.6 for Piano 3D against 3.5 for Keyboard Instrument Simulator. That said, the two scores are not equally well evidenced: Keyboard Instrument Simulator has 81 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 80% of Piano 3D's written reviews are positive against 13% of Keyboard Instrument Simulator's.

Piano 3D ships an update every 6 weeks, Keyboard Instrument Simulator every 3 weeks. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
