# Sonitus vs Frequency

The clearest difference is review sentiment: Frequency at 70% against Sonitus's 25%. Frequency also leads on rating (4.7 vs 3.0) and ratings volume (340 vs 4). Sonitus's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). 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.

Frequency holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Frequency has 340 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 25% of Sonitus's written reviews are positive against 70% of Frequency's.
