Assign custom ringtones to your contact groups and have your future contacts automatically inherit the ringtone of the group they belong to.
Ever wondered why your old dumb phones supported this feature since ages but not your shiny new Android device? Well, think no more: grab GroupTone and start enjoying group ringtones right away.
A word of advice: contacts with multiple groups might inherit any of the ringtones selected for those groups, organize your contacts accordingly.
Explanation of permissions required:
Read contacts: to query the contact groups
Write contacts: to update contact ringtones
Receive boot completed: to start the update service in case your device is restarted
