Grouptones lets you assign a unique ringtone and text tone to each of your contact groups. From now on you’ll know who’s calling without even looking at your iPhone.
– You’re still able to assign ringtones and text tones to individual contacts
– Supports local, MobileMe, and Google contact groups
– Supports FaceTime calls
– Smoothly integrates into system apps rather than being a separate application
iPhone's contacts list does not show groups unless you create them by syncing some from your Mac/PC beforehand
No new icons are created for your homescreen. There are no options to configure for this tweak.
