Verdict
The clearest difference is rating: OneMail at 4.4 against black.com's 3.7. OneMail also leads on update cadence (every 9 days vs every 6 weeks) and ratings volume (298 vs 12). black.com's advantage is review sentiment (73% vs 34%) and ads (none vs shown). On price, in-app purchases, monetization model and device support 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. OneMail sells 4 in-app purchases, starting at $1.99 per month and black.com sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
OneMail holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: OneMail has 298 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 34% of OneMail's written reviews are positive against 73% of black.com's, so the app with the better star average is not the one people write more warmly about.
OneMail ships an update every 9 days, black.com every 6 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
