# AWS vs CLF

The clearest difference is rating: CLF at 5.0 against AWS's 4.5. CLF also leads on update cadence (every 10 days vs every 3 months). AWS's advantage is ratings volume (11 vs 1) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AWS sells 1 one-off in-app purchase and CLF sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CLF holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: AWS has 11 ratings behind it against 1, so its average is the more settled of the two.

AWS ships an update every 3 months, CLF every 10 days. The most recent releases landed on August 19, 2026 and August 22, 2026 respectively.
