# TLevels vs Cozy

The clearest difference is ratings volume: TLevels at 11 against Cozy's 1. TLevels also leads on update cadence (every 5 days vs every 2 weeks) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. TLevels sells 2 in-app purchases, starting at $24.99 per month and Cozy sells 3 in-app purchases, starting at $4.99 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 TLevels against 5.0 for Cozy. That said, the two scores are not equally well evidenced: TLevels has 11 ratings behind it against 1, so its average is the more settled of the two.

TLevels ships an update every 5 days, Cozy every 2 weeks. The most recent releases landed on October 15, 2026 and October 28, 2026 respectively.
