Verdict
The clearest difference is review sentiment: mail.ee at 100% against Zero's 25%. mail.ee also leads on ratings volume (101 vs 3) and update cadence (every 9 days vs monthly). Zero's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.8). On price, ads 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. mail.ee sells 1 in-app purchase, starting at $1.99 per month. Zero asks for nothing beyond the download.
Zero holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: mail.ee has 101 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of mail.ee's written reviews are positive against 25% of Zero's, so the app with the better star average is not the one people write more warmly about.
mail.ee ships an update every 9 days, Zero monthly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
