The app has been really useful to me, I recommend it especially if you are trying out new clothing or shoes! It can be quite time consuming at times with all of your photos having different angles etc. However after about 5 minutes this really does start working its magic for getting results that make sense, even when there's not much information available initially eg sizing, which leads into difficulty shopping online as more product gets added/located! Would love an easier way to add measurements from third parties such as my GP surgery, perhaps linking to their systems directly? So far so good though, results have always made sense once reviewed using photo's taken of actual clothes before hand - usually via google cardboard camera too (not just straight pictures). App works well overall, easy enough to use but some extra info would help eg exact size range where possible rather than say "2" sizes larger/smaller than average eg 2 bands smaller). More accurate data collection across The accuracy of this product is incredible, it's easy to use & very comfortable for me (a plus). I've used other products with similar features but nothing beats how accurate these are! It can be difficult at times keeping up w/the app as well. If you're looking for something that will help you achieve your goals then look no further than 3dlook. They have helped me improve my posture by helping me find some areas where i need to work on improving myself.
