# Tuner+ vs CarlTune

The clearest difference is update cadence: CarlTune at every 8 days against Tuner+'s every 6 months. Tuner+'s advantage is rating (4.7 vs 4.3) and ratings volume (1.1K vs 62). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Tuner+ sells 1 one-off in-app purchase and CarlTune sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Tuner+ holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Tuner+ has 1.1K ratings behind it against 62, so its average is the more settled of the two. Written reviews point the same way: 82% of Tuner+'s written reviews are positive against 68% of CarlTune's.

Tuner+ ships an update every 6 months, CarlTune every 8 days. Both last shipped on November 1, 2026.
