# Pitch trainer vs Tuner (チューナー)

The clearest difference is in-app purchases: Tuner (チューナー) at none against Pitch trainer's 7. Tuner (チューナー) also leads on ads (none vs shown) and review sentiment (100% vs 68%). Pitch trainer's advantage is update cadence (every 3 days vs every 123 months) and rating (4.4 vs 4.0). On price and device support there is nothing between them.

Both are free to download. Pitch trainer sells 7 one-off in-app purchases. Tuner (チューナー) asks for nothing beyond the download.

Pitch trainer holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Pitch trainer has 413 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of Pitch trainer's written reviews are positive against 100% of Tuner (チューナー)'s, so the app with the better star average is not the one people write more warmly about.

Pitch trainer ships an update every 3 days, Tuner (チューナー) every 123 months. The most recent releases landed on September 23, 2026 and June 1, 2026 respectively.
