# Tuta Mail vs CryoStats

The clearest difference is ratings volume: Tuta Mail at 3.8K against CryoStats's 2. CryoStats's advantage is rating (5.0 vs 4.7) and update cadence (every 2 days vs weekly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Tuta Mail sells 4 in-app purchases, starting at $3.99 per month and CryoStats sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

CryoStats holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Tuta Mail has 3.8K ratings behind it against 2, so its average is the more settled of the two.

Tuta Mail ships an update weekly, CryoStats every 2 days. The most recent releases landed on November 3, 2026 and October 7, 2026 respectively.
