# RTAB vs OpenPlan3D

The clearest difference is update cadence: OpenPlan3D at monthly against RTAB's every 4 months. OpenPlan3D also leads on rating (5.0 vs 4.8). RTAB's advantage is ratings volume (39 vs 4) and iOS requirement (14.3 vs 26.2). On price, review sentiment, ads and in-app purchases there is nothing between them.

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