Ratings and reviews

I loaded the app onto my phone and it asks that I grant permissions that are required by android but the specific permissions are not given. I don't know if i'm granting permissions for location and WiFi access which would be acceptable or if i'm giving more dangerous permissions such as contact access or ability to send/receive text messages. As an android developer, the specific permissions being granted should always be stated along with the reason. A link is given in the pop-up that leads to an android developer page but for non-developers this is not helpful and could potentially be misleading. This app looks great but unfortunately until this issue is fixed i will be searching for another app.

this app fails to import images, all permissions have been granted, it can find the image, but fails with a very quick error, and then loads its default plan. I have contacted the author 3 times in the last 2 weeks, it seems he has lost interest in supporting his app.

Functionality: the best WiFi analyzer APP that I've tested. It would make 5 stars if it was just for this. (even if it is not the prettiest APP) Stability: I had several crashes accessing the graphs. Ads: there's no paid update to remove ads.
