Verdict
The clearest difference is price: Thermal Vision FX Camera at Free against Motion Sensor's $4.99. Thermal Vision FX Camera also leads on rating (4.4 vs 4.2) and ratings volume (793 vs 257). Motion Sensor's advantage is ads (none vs shown) and review sentiment (39% vs 21%). On update cadence, in-app purchases and device support there is nothing between them.
