# CDL Help vs Calm Drive

The clearest difference is update cadence: CDL Help at every 2 days against Calm Drive's every 3 weeks. CDL Help also leads on ratings volume (5.4K vs 1) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CDL Help sells 5 in-app purchases, starting at $9.99 per 7 days and Calm Drive sells 1 in-app purchase, starting at $0.99 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 — 4.9 for CDL Help against 5.0 for Calm Drive. That said, the two scores are not equally well evidenced: CDL Help has 5.4K ratings behind it against 1, so its average is the more settled of the two.

CDL Help ships an update every 2 days, Calm Drive every 3 weeks. The most recent releases landed on November 12, 2026 and November 6, 2026 respectively.
