# SLII® vs Amazon Quick

The clearest difference is rating: Amazon Quick at 5.0 against SLII®'s 3.3. SLII®'s advantage is review sentiment (58% vs 30%) and ratings volume (28 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Amazon Quick holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: SLII® has 28 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of SLII®'s written reviews are positive against 30% of Amazon Quick's, so the app with the better star average is not the one people write more warmly about.

SLII® ships an update every 3 weeks, Amazon Quick fortnightly. The most recent releases landed on September 10, 2026 and September 22, 2026 respectively.
