# iClef vs Music Theory 101

The clearest difference is price: Music Theory 101 at Free against iClef's $2.99. Music Theory 101 also leads on rating (4.8 vs 4.2) and update cadence (every 5 days vs every 2 months). iClef's advantage is review sentiment (100% vs 83%). On ads, in-app purchases and device support there is nothing between them.

Music Theory 101 is free to download; iClef costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Music Theory 101 holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Music Theory 101 has 71 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of iClef's written reviews are positive against 83% of Music Theory 101's, so the app with the better star average is not the one people write more warmly about.

iClef ships an update every 2 months, Music Theory 101 every 5 days. Both last shipped on November 3, 2026.
