# Tuner+ vs Cello Tuner

The clearest difference is rating: Tuner+ at 4.7 against Cello Tuner's 3.8. Tuner+ also leads on review sentiment (82% vs 59%) and ratings volume (1.1K vs 17). Cello Tuner's advantage is update cadence (monthly vs every 6 months). 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 Cello Tuner sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
