# 4Warning vs Clean Wave°

The clearest difference is rating: Clean Wave° at 4.5 against 4Warning's 1.5. Clean Wave° also leads on ratings volume (451 vs 2) and review sentiment (100% vs 80%). 4Warning's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 4Warning sells 1 in-app purchase, starting at $3.99 per year and Clean Wave° sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Clean Wave° holds the better App Store score, 4.5 against 1.5. That said, the two scores are not equally well evidenced: Clean Wave° has 451 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 80% of 4Warning's written reviews are positive against 100% of Clean Wave°'s.

4Warning ships an update every 2 weeks, Clean Wave° every 2 months. The most recent releases landed on October 4, 2026 and October 7, 2026 respectively.
