# CLF vs ReadySec

The clearest difference is update cadence: ReadySec at every 2 days against CLF's every 2 weeks. ReadySec also leads on ratings volume (8 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. CLF sells 4 in-app purchases, starting at $9.99 per 7 days and ReadySec sells 10 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for CLF against 5.0 for ReadySec. That said, the two scores are not equally well evidenced: ReadySec has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

CLF ships an update every 2 weeks, ReadySec every 2 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
