# Physics Lab AR vs Sundial 3D Science Experiment

The clearest difference is review sentiment: Sundial 3D Science Experiment at 100% against Physics Lab AR's 48%. Sundial 3D Science Experiment also leads on update cadence (every 8 days vs every 2 months) and rating (5.0 vs 4.7). Physics Lab AR's advantage is ratings volume (1.9K vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Physics Lab AR sells 7 in-app purchases, starting at $1.49 per month and Sundial 3D Science Experiment sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sundial 3D Science Experiment holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Physics Lab AR has 1.9K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 48% of Physics Lab AR's written reviews are positive against 100% of Sundial 3D Science Experiment's.

Physics Lab AR ships an update every 2 months, Sundial 3D Science Experiment every 8 days. The most recent releases landed on October 22, 2026 and October 7, 2026 respectively.
