# black.com vs Tuta Calendar

The clearest difference is rating: Tuta Calendar at 4.6 against black.com's 3.6. Tuta Calendar also leads on update cadence (weekly vs every 6 weeks) and ratings volume (160 vs 9). black.com's advantage is review sentiment (67% vs 56%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. black.com sells 1 in-app purchase, starting at $4.99 per month and Tuta Calendar sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Tuta Calendar holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Tuta Calendar has 160 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 67% of black.com's written reviews are positive against 56% of Tuta Calendar's, so the app with the better star average is not the one people write more warmly about.

black.com ships an update every 6 weeks, Tuta Calendar weekly. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
