The call

The clearest difference is price: Notevision at Free against Clef Trainer Grid's $2.99. Notevision also leads on ratings volume (3.2K vs 12). Clef Trainer Grid's advantage is in-app purchases (none vs 1) and update cadence (daily vs weekly). On review sentiment, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Clef Trainer Grid holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Notevision has 3.2K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 89% of Notevision's written reviews are positive against 83% of Clef Trainer Grid's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Notevision ships an update weekly, Clef Trainer Grid daily. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
