# Tone generator vs Frequency

Tone generator and Frequency both sit at 4.0 stars, but that hides the real split: 67% of Tone generator's written reviews are positive against 0% of Frequency's. Tone generator also leads on ratings volume (155 vs 24) and iOS requirement (12.0 vs 16.0). Frequency's advantage is ads (none vs shown) and update cadence (every 10 days vs every 5 months). On price, rating, in-app purchases and monetization model there is nothing between them.

That said, the two scores are not equally well evidenced: Tone generator has 155 ratings behind it against 24, so its average is the more settled of the two.
