# PhysicsLab vs 3DPhyS

The clearest difference is update cadence: 3DPhyS at fortnightly against PhysicsLab's every 3 months. 3DPhyS also leads on monetization model (ad-supported vs free with in-app purchases). PhysicsLab's advantage is review sentiment (100% vs 80%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PhysicsLab ships an update every 3 months, 3DPhyS fortnightly. The most recent releases landed on September 9, 2026 and August 6, 2026 respectively.
