SL Visual holds the better App Store score, 2.5 against 1.8. That said, the two scores are not equally well evidenced: Cooleer has 135 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 16% of Cooleer's written reviews are positive against 14% of SL Visual's, so the app with the better star average is not the one people write more warmly about.
Cooleer ships an update monthly, SL Visual every 4 weeks. The most recent releases landed on October 14, 2026 and October 17, 2026 respectively.
