# Lab4U vs Unreal Chemist

Lab4U and Unreal Chemist both sit at 4.5 stars, but that hides the real split: 73% of Unreal Chemist's written reviews are positive against 36% of Lab4U's. Unreal Chemist also leads on ratings volume (68 vs 10) and iOS requirement (11.0 vs 15.0). Lab4U's advantage is ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Lab4U sells 4 one-off in-app purchases and Unreal Chemist sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Lab4U against 4.5 for Unreal Chemist. That said, the two scores are not equally well evidenced: Unreal Chemist has 68 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 36% of Lab4U's written reviews are positive against 73% of Unreal Chemist's.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
