Verdict
The clearest difference is rating: OneMail at 4.4 against Zero Inbox's 3.7. OneMail also leads on ratings volume (297 vs 3) and update cadence (every 9 days vs every 3 weeks). Zero Inbox's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price, device support and iOS requirement 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. Zero Inbox asks for nothing beyond the download.
OneMail holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: OneMail has 297 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Zero Inbox's written reviews are positive against 34% of OneMail's, so the app with the better star average is not the one people write more warmly about.
Zero Inbox ships an update every 3 weeks, OneMail every 9 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
