Verdict
The clearest difference is rating: BLACKCELL at 5.0 against GenMail's 4.7. GenMail's advantage is update cadence (weekly vs monthly) and ratings volume (18 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BLACKCELL sells 2 in-app purchases, starting at $2.99 per month and GenMail sells 10 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
BLACKCELL holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: GenMail has 18 ratings behind it against 1, so its average is the more settled of the two.
BLACKCELL ships an update monthly, GenMail weekly. The most recent releases landed on October 31, 2026 and November 7, 2026 respectively.
