Free and indispensable
Ok, there are issues with this app, but the service is so vital to my family that I would literally pay Google every month to use this app. Google Voice gives you a phone number that you can fully access over wifi, on an iPad, or on an old phone that has no carrier service. You can use it to text, call, or use in any way. That is awesome! My kid was 5 and I got her a number. That let her text her aunt and uncle!
Add in the controls to turn off the ringer during quiet hours, or to block individual numbers, and GV becomes vital!
