Verdict

The call

The clearest difference is rating: OneMail at 4.4 against UK Postbox's 2.3. OneMail also leads on ratings volume (297 vs 3) and update cadence (every 9 days vs monthly). UK Postbox's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OneMail holds the better App Store score, 4.4 against 2.3. 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: 54% of UK Postbox'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.

UpkeepUpdate frequency

UK Postbox ships an update monthly, OneMail every 9 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
