Number Book is a free piece of software available for the Android operating system and it lets you keep in touch with your friends and family. This app works mostly like WhatsApp, but it comes with some nice features. Using this one you can create profiles for each contact located on your smartphone and you can see this information each time a saved contact calls you.
One of its best features is the ability to check and identify spammy and unwanted calls. The included messaging system lets users add emojis, attach videos and photos, share GPS information and more. It also comes with a built-in searching function that lets you find contacts easier. This small feature helps a lot if you have plenty of contacts. When it comes to its user interface, this handy application comes with a modern and intuitive window layout.
You shouldn't have issues using it even if you're a newbie smartphone user. If an unwanted number keeps annoying you, the blocking function will save you. Another good feature is the backup utility which lets you create a copy of your contacts list and restore it when you need it.
