# Polyphasic sleep vs Quitzilla

The clearest difference is rating: Quitzilla at 4.8 against Polyphasic sleep's 3.8. Quitzilla also leads on review sentiment (73% vs 50%) and ratings volume (1.5K vs 47). Polyphasic sleep's advantage is update cadence (every 5 weeks vs every 10 months) and iOS requirement (9.0 vs 26.0).

Both are free to download. Polyphasic sleep sells 1 one-off in-app purchase and Quitzilla sells 7 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
