# YHW vs uLamp

The clearest difference is rating: YHW at 2.1 against uLamp's 1.7. uLamp's advantage is review sentiment (16% vs 0%) and ratings volume (80 vs 14). 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.

YHW holds the better App Store score, 2.1 against 1.7. That said, the two scores are not equally well evidenced: uLamp has 80 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 0% of YHW's written reviews are positive against 16% of uLamp's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on October 24, 2026.
