Ratings and reviews

Lacks even a way to find a file you want to open and is unable to locate it on its own. I probably should have anticipated the app wouldn't know how a JSON file looks like since judging by the screenshots neither do its' creators.

Horrible app. Did not even work and somehow signed me up for some streaming service without my permission and charged my card (which they explicitly stated they wouldn't do). Absolutely terrible and scummy.

Waste of time you can go through just about anything but not everything literally cannot find a single app that will do what it says about going through a file and letting you go through it and see it because once you go through it it has these things where you can't click them what's the point of the app what's the point of it what is the point if you can't go through every file that you want to go through what is the point
