# Cooleer vs SL Visual

The clearest difference is rating: SL Visual at 2.5 against Cooleer's 1.8. SL Visual also leads on iOS requirement (13.0 vs 15.0). Cooleer's advantage is ratings volume (135 vs 11). On price, review sentiment, update cadence and ads there is nothing between them.

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

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.
