# Lab4U vs SciQuiz

The clearest difference is in-app purchases: SciQuiz at none against Lab4U's 4. SciQuiz also leads on review sentiment (67% vs 36%) and ratings volume (53 vs 10). Lab4U's advantage is ads (none vs shown) and update cadence (fortnightly vs every 3 months). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Lab4U sells 4 one-off in-app purchases. SciQuiz asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for Lab4U against 4.6 for SciQuiz. That said, the two scores are not equally well evidenced: SciQuiz has 53 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 67% of SciQuiz's.

Lab4U ships an update fortnightly, SciQuiz every 3 months. The most recent releases landed on August 15, 2026 and September 20, 2026 respectively.
