# Khan Academy vs Physics Lab AR

The clearest difference is in-app purchases: Khan Academy at none against Physics Lab AR's 7. Khan Academy also leads on review sentiment (74% vs 47%) and ratings volume (110K vs 1.8K). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Physics Lab AR sells 7 in-app purchases, starting at $1.49 per month. Khan Academy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Khan Academy against 4.7 for Physics Lab AR. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 1.8K, so its average is the more settled of the two. Written reviews are what separate them: 74% of Khan Academy's written reviews are positive against 47% of Physics Lab AR's.

Khan Academy ships an update every 6 weeks, Physics Lab AR every 2 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
