TouchyNotes 4+

This is a really cool little app! I agree with other reviewers who say this should be a home screen unlock on iPhone. You can use the SPINT technology or not, depending on your surroundings, so it can be just as fast (but more secure!) as typing in a number or tracing a pattern.
I love that the information you have saved in this app is also mostly hidden unless you choose to uncover it, so people around you can't read your entire screen.
I happily paid the $.99 for the extra file storage after seeing what this app could do. I will be sharing this with my friends who value their privacy!

TouchyNotes is one of the most secure and feature-rich photo hiding apps. It utilizes a combination of spinning controls and a magic point that is used to register your input, thus, making it difficult for people to guess the numbers you entered. TouchyNotes keeps your photos, passwords, website bookmarks, contacts, and notes private and away from curious bodies.

The process of adding content, i.e. photos, notes, etc may be a little tedious and require you to paste it all from the clipboard, but I love that TouchyNotes adds a black screen to your photos for further privacy.

TouchyNotes contains spinning buttons which keeps on rotating even when you press the buttons. The spinning combination makes it difficult to guess or see the password providing more secure feature. To provide more security, you cannot just drag and drop the pictures. You have to copy the data to clipboard and then paste it in the app and further the UI of the app is in dark mode which makes difficult to see the hidden pictures. Don't you think it's amazing? Tapping and revealing pictures just like magic.
