I like the approach - its quite useful for those glitches in the network where wi-fi drops out for some reason. However, its marginally useful for recording over time and needs software that will run on IOS or on a PC. They show graphics in the manual - which they imply you can create. but they only make mention of an app for android. I would not have purchased it, if I had known that - MD you listening?
I like the idea and do use it to find "channels to avoid" - but without the software I would not recommend given the price paid.
