For the most part I like the app. However two things, one very troubling, keep this from being better. First, it would be nice if you could rearrange pics inside of a folder to be in a certain order. I've found a laborious work around, so it's annoying but not enough to detract from the overall app.
I took 2 Stars away for this:
Whether you are in decoy or private mode, when you close out, the next time you log in regardless of password, it takes you back to where you were. For example if you were in private mode, close out and re enter the decoy password, it takes you back into your PRIVATE area and not decoy. Fix this and it will get rated higher. Otherwise not sure I'd recommend it.
