Contacts 3 is a contacts manager with one very unique feature: encryption of your notes per contact. Otherwise, it looks about as plain as can be, but very good color themes.
The app basically has 4 tabs as show here:
Contacts -- list of all the contacts
Connect -- shows the details of the contact, such as phone number
Notes -- displays note of this contact, can be encrypted
Tools -- config settings, including entering the password to decrypt, choose color themes, and so on.
Other than, the ability to encrypt the notes, and pastel color UI, there really isn't much to recommend about Contacts 3.
There is a Pro version for $2.88 that removes the ads.
