# Laifen vs SilkPass

The clearest difference is rating: Laifen at 2.4 against SilkPass's 2.0. Laifen also leads on ratings volume (78 vs 9). SilkPass's advantage is review sentiment (40% vs 29%) and iOS requirement (12.0 vs 15.0). 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.

Laifen holds the better App Store score, 2.4 against 2.0. That said, the two scores are not equally well evidenced: Laifen has 78 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 29% of Laifen's written reviews are positive against 40% of SilkPass's, so the app with the better star average is not the one people write more warmly about.

Laifen ships an update every 3 weeks, SilkPass every 4 weeks. The most recent releases landed on September 25, 2026 and September 11, 2026 respectively.
