# mail.com vs OSO+

The clearest difference is price: mail.com at Free against OSO+'s $19.99. mail.com also leads on ratings volume (105K vs 6) and update cadence (fortnightly vs every 2 months). OSO+'s advantage is ads (none vs shown) and review sentiment (100% vs 76%). On in-app purchases, monetization model and device support there is nothing between them.

mail.com is free to download; OSO+ costs $19.99 up front. mail.com sells 6 in-app purchases, starting at $0.99 per month and OSO+ sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

OSO+ holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: mail.com has 105K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 76% of mail.com's written reviews are positive against 100% of OSO+'s.

mail.com ships an update fortnightly, OSO+ every 2 months. The most recent releases landed on October 20, 2026 and October 12, 2026 respectively.
