About WhoWho

Use WhoWho as default caller. Provides many convenient functions (ex. widget)

What WhoWho Is Used For

WhoWho appears to be a communication app for handling phone calls and contact-related tasks on Android phones. Based on the metadata, it may be used as a default caller app, which suggests it can sit in the middle of everyday calling activity such as placing calls, answering calls, and showing caller-related information. The mention of a widget also suggests it may offer quick access from the home screen for people who want faster calling or contact lookup.

The permissions point to a more feature-rich phone utility than a simple dialer. Access to contacts, call logs, SMS, and phone state indicates it may support managing recent calls, reading caller details, and possibly integrating texting or messaging features. Location, audio, notification, and background-related permissions suggest some functions may run in the background or support call-related features that depend on device context. Because it is listed as a phone app, it is most relevant for everyday smartphone use rather than tablets or TV devices.

Common uses

  • Set as a default caller app for everyday phone use
  • Access contacts and call history from one place
  • Use home screen widgets for quicker dialing or lookup
  • Manage incoming and outgoing call-related actions
  • May support SMS and messaging-related phone workflows
  • Useful for users who want a call-focused communication app
  • Phone app intended for regular Android handset use
Best for:
Phone users Default caller use Call management Quick dialing Home screen widgets
