# black.com vs Mamoism

The clearest difference is rating: Mamoism at 5.0 against black.com's 3.7. Mamoism also leads on update cadence (every 5 days vs every 6 weeks). black.com's advantage is ratings volume (12 vs 1). 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 Mamoism sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Mamoism holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: black.com has 12 ratings behind it against 1, so its average is the more settled of the two.

black.com ships an update every 6 weeks, Mamoism every 5 days. The most recent releases landed on November 3, 2026 and November 9, 2026 respectively.
