Twomon SE's advantage is in-app purchases (none vs 11) and review sentiment (85% vs 71%). On ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

spacedesk holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: spacedesk has 2.3K ratings behind it against 57, so its average is the more settled of the two. Written reviews complicate that: 71% of spacedesk's written reviews are positive against 85% of Twomon SE's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

spacedesk ships an update every 3 weeks, Twomon SE every 6 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
