Good App, poor manuals and instructions, difficult to use
This app is very sophisticated and claims to measure many indicators very precisely. This seems to be true. However, figuring oit how to use it and how to Interprete the gathered data is hard to figure out if you are not already an expert in the field. The faq and support is done Only on the website with links to some pdfs and youtube videos. Some instructions are more like a scientific paper. No structure at all. For that price, i would expect much more. Besides, the graph carts are not browsable on iphone x (which is not listed as compatible phone thoug). And the user experience is quite low tech.
