# Tuner T1 vs KeyTuner

The clearest difference is ads: KeyTuner at none against Tuner T1's shown. KeyTuner also leads on review sentiment (91% vs 62%) and monetization model (free vs free with in-app purchases). Tuner T1's advantage is chart position (#100 vs unranked) and ratings volume (11K vs 1.8K). On price, 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.
