After installing this app I was pleased to find that I was able to do the basic things I needed - storing images and secret browsing. The browser allows for full-screen watching of videos, bookmarks, multiple tabs, etc. The calculator is a nice way to hide the existence of the vault. And the $1.99 price can't be beat, especially with so many similar apps charging ongoing subscription fees. The one thing I could wish for is a better way to handle backups besides WiFi or iTunes transfer to another computer. What would be nice would be a way of selecting all of one's photos and other hidden content, adding it to a password- protected zip file, and uploading it to, cloud-drive Dropbox, Google Drive, or just sending it via FTP or secure FTP.
There's a few areas that could use a little touch up that would make this great app even better. For example, the notes section is very glitchy and it would be nice to be able to import notes. Also to be able to chose what button takes the picture on your device, which camera to use, to have the light when you take a secret picture, the theme of the calculator, etc. Little things like that fixed up or added could make this app better than it already is, and it's already pretty great.
Its the first time that i am writing a review. I was wondering if i could backup my photos as well along with notes and contacts and save it encrypted on other storage apps. I think the way to see my album should be more organized. It would better if - "subtraction sign" of the calculator would enable to take photo from front camera to know the intruders. Also the = "equals sign" should allow to take videos with black screen or calculator screen itself. Also the notes could include pictures and all... I bought this app thinking its great and it was great indeed. Maybe addition of new more features would get six stars out of five. Really looking forward to it. Thank you ... created of this wonderful app. Also add wifi transfer function and remove itunes sharing function. Its not secret if itunes allows to copy files from the app.
