The app looks nice and gives a convenient way to manage the hotspot.
But here are some things that need to be improved to be useful:
Using this application in combination with the E5377s it does not show a graph for the daily used traffic.
If browsing through the ad cards files and folders - the file browser does not show thumbnails for images and videos what makes it nearly impossible to find a picture once it is uploaded without editing its filename.
Moving files to this app from other applications via share sheet is missing. Exporting from the app to others as well - which kind of disqualifies the whole idea of having access to an SD Card from youre iOS device.
