# Mailo vs Citadel Team

The clearest difference is rating: Mailo at 4.0 against Citadel Team's 2.6. Mailo also leads on iOS requirement (11.0 vs 13.0). Citadel Team's advantage is ads (none vs shown) and review sentiment (51% vs 29%). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Mailo holds the better App Store score, 4.0 against 2.6. That said, the two scores are not equally well evidenced: Citadel Team has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 29% of Mailo's written reviews are positive against 51% of Citadel Team's, so the app with the better star average is not the one people write more warmly about.

Mailo ships an update every 7 months, Citadel Team every 2 months. The most recent releases landed on September 15, 2026 and September 18, 2026 respectively.
