# Physics Lab AR vs PE.Mech[Lite]

The clearest difference is in-app purchases: PE.Mech[Lite] at none against Physics Lab AR's 7. PE.Mech[Lite] also leads on rating (5.0 vs 4.7). Physics Lab AR's advantage is ratings volume (1.8K vs 1) and device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.

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

PE.Mech[Lite] 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 1.8K ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 14, 2026 and September 23, 2026 respectively.
