SGMemo app review: simple and secure note-taking



SGMemo is a simple little app for your iPhone and iPad that you can use to take down important notes or write diary and journal entries before locking them up securely with passcode protection.

The best iPhone apps for note-taking

If you’ve got things you’d like to jot down but don’t want other people seeing them then I think that a simple utility such as this will give you pretty much what you need to achieve this without the added bells and whistles that often come with this kind of app.



Notes... and then Some!

What we have here is a very basic app that is essentially not all that different to the native iOS Notes widget, of course with the exception that you can add passcode protection to keep your notes a little more secure.

The best iPad apps for creating lists

Another added feature that this app offers is the option to sort your notes into different groups or categories, so if you write a lot this should help to keep things a little more organized.

Personally I don’t see why Apple doesn’t enhance the iOS Notes functionality, but I guess until they do we’ll rely on handy apps like this!
