It was great..until it lost my files

I use this app a lot when I scout locations for photo and video shoots. I can coordinate the time stamp on the photo file with the times on the saved drive.
That is, until yesterday when my whole cache of drives disappeared. I have to start all over and may not find some locations in rural areas again. Now Im not sure whether to trust the app or look for a new one
