App gives unreliable readings, website is poor – Dark Sky Meter Review

I had used this at home in Bortle class 6 area and the readings seemed reasonable. Then I took it to a dark site, listed as one of the darkest areas in the continental US. I got multiple failures from the app, and finally it gave me a reading of bright suburban sky. At this point I gave up. I do not believe this app is trustworthy
