If you’re looking for a secure and personalized social networking tool that finds people you know and may know, Number Book might be for you!

NumberBook Social uses your address book to find all your friends and send them messages – and you’ll also be able to connect with other Numberbook users that have your friends in their phonebooks, too!

One of the greatest features of Numberbook is the fact that you only share the information you want to share; your phone number, full name, location, etc. is all private.

With Number Book you’ll be able to send up to a million messages a day. Yes, a million messages! We’re not sure why you’d need to be able to send that many messages every day, but it’s an option with this app.

You can also personalize all of your contacts with unique photos and nicknames, so you can keep everyone organized and easy to find.

One problem we’ve seen is that many users are unable to delete their profiles after they’ve created them. This means that once you’ve made an account you might be in the system forever, just something to think about.

All in all Number Book is an interesting way to find and chat with friends and friends of friends.


  • Switch Back and Forth Between SMS and NumberBook Social You can switch back and forth between SMS and Number Book, so you can stay connected even when you’re off network.
  • Send Up to a Million Messages Everyday! Yes, a million.
  • Personalize with Photos, Nicknames, and More Customize and organize your contacts.


  • Unable to Delete Your Profile You might not be able to delete your account.

Potentially dangerous permissions

  • ACCESS_COARSE_LOCATION: Allows an app to access approximate location. Alternatively, you might want ACCESS_FINE_LOCATION.
  • ACCESS_FINE_LOCATION: Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.
  • CALL_PHONE: Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call.
  • CAMERA: Required to be able to access the camera device.
  • GET_ACCOUNTS: Allows access to the list of accounts in the Accounts Service.
  • PROCESS_OUTGOING_CALLS: Allows an application to see the number being dialed during an outgoing call with the option to redirect the call to a different number or abort the call altogether.
  • READ_CALL_LOG: Allows an application to read the user's call log.
  • READ_CONTACTS: Allows an application to read the user's contacts data.
  • READ_EXTERNAL_STORAGE: Allows an application to read from external storage.
  • READ_PHONE_STATE: Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
  • READ_SMS: Allows an application to read SMS messages.
  • RECEIVE_SMS: Allows an application to receive SMS messages.
  • RECEIVE_WAP_PUSH: Allows an application to receive WAP push messages.
  • RECORD_AUDIO: Allows an application to record audio.
  • SEND_SMS: Allows an application to send SMS messages.

Other permissions

  • ACCESS_NETWORK_STATE: Allows applications to access information about networks.
  • GET_TASKS: This constant was deprecated in API level 21. No longer enforced.
  • INSTALL_SHORTCUT: Allows an application to install a shortcut in Launcher.
  • INTERNET: Allows applications to open network sockets.
  • MODIFY_AUDIO_SETTINGS: Allows an application to modify global audio settings.
  • RECEIVE_BOOT_COMPLETED: Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
  • SYSTEM_ALERT_WINDOW: Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.
  • VIBRATE: Allows access to the vibrator.
  • WAKE_LOCK: Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.
  • android.permission.LISTEN_DATA_ACTIVITY
  • android.permission.LISTEN_DATA_CONNECTION_STATE
  • android.permission.READ_SOCIAL_STREAM
  • android.permission.STORAGE
  • android.permission.USE_CREDENTIALS
  • android.permission.WRITE_SMS
