# Clean Wave vs Frequency Generator

The clearest difference is rating: Frequency Generator at 5.0 against Clean Wave's 4.4. Clean Wave's advantage is ratings volume (2.8K vs 16) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Clean Wave sells 4 in-app purchases, starting at $2.99 per month and Frequency Generator sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Frequency Generator holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Clean Wave has 2.8K ratings behind it against 16, so its average is the more settled of the two.
