The visual displacement meter is a high-precision visual measurement device used to measure surface displacement changes of structures, with a measurement accuracy of up to sub-millimeter levels and a maximum measurement distance of hundreds of meters.

Verdict
The clearest difference is update cadence: Visual Displacement Meter at fortnightly against Luna智能广播's every 7 months. Luna智能广播's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
