# NB实验室 vs Physics Lab AR

NB实验室 and Physics Lab AR both sit at 4.8 stars, but that hides the real split: 72% of NB实验室's written reviews are positive against 47% of Physics Lab AR's. NB实验室 also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (13.0 vs 15.0). Physics Lab AR's advantage is ratings volume (1.8K vs 83). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. NB实验室 sells 41 in-app purchases, starting at $4.99 per month and Physics Lab AR sells 7 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for NB实验室 against 4.7 for Physics Lab AR. That said, the two scores are not equally well evidenced: Physics Lab AR has 1.8K ratings behind it against 83, so its average is the more settled of the two. Written reviews are what separate them: 72% of NB实验室's written reviews are positive against 47% of Physics Lab AR's.

NB实验室 ships an update fortnightly, Physics Lab AR every 2 months. Both last shipped on September 28, 2026.
