# Digital Circuit Simulator Lite vs Physics Lab AR

The clearest difference is rating: Physics Lab AR at 4.7 against Digital Circuit Simulator Lite's 2.8. Physics Lab AR also leads on ratings volume (1.8K vs 29) and review sentiment (47% vs 33%). Digital Circuit Simulator Lite's advantage is in-app purchases (none vs 7) and update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.

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

Physics Lab AR holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: Physics Lab AR has 1.8K ratings behind it against 29, so its average is the more settled of the two. Written reviews point the same way: 33% of Digital Circuit Simulator Lite's written reviews are positive against 47% of Physics Lab AR's.

Digital Circuit Simulator Lite ships an update fortnightly, Physics Lab AR every 2 months. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
