# Cello Tuner vs Kindoo

The clearest difference is ads: Kindoo at none against Cello Tuner's shown. Kindoo also leads on update cadence (every 4 weeks vs every 15 months) and monetization model (free vs ad-supported). Cello Tuner's advantage is rating (3.9 vs 3.6) and ratings volume (252 vs 38). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Cello Tuner holds the better App Store score, 3.9 against 3.6. That said, the two scores are not equally well evidenced: Cello Tuner has 252 ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 44% of Cello Tuner's written reviews are positive against 47% of Kindoo's, so the app with the better star average is not the one people write more warmly about.

Cello Tuner ships an update every 15 months, Kindoo every 4 weeks. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
