GrooVe IP is an app that Google Voice should be. A free download from the Play Store, GrooVe IP Lite lets you make VOIP calls from your handheld Android device. I know a few of you are thinking that’s the point of Google voice, but there is a difference. The official Google Voice app for Android makes a “call back” call. Basically, you dial a number, and via your data connection, a signal gets sent to the Google Voice servers. Then the server calls you. Once a call to you is established, it rings the person you called, connecting the two of you. Microsoft’s Lync app works the same way. But this uses your normal cell phone minutes – the only real benefit is that the call looks like it is coming from your Google voice number instead of your personal cell phone.
GoorVe IP Lite allows you to make calls truly using WiFi. You could make a call with a tablet, provided it has a Microphone. A $4.99 Pro Version can make calls over your phone’s 3G/4G mobile data connection – no WiFi required!
As I said above, I really feel like this is what the Google Voice app should’ve been. You could discontinue your phone service, carry your Android phone with you, and use it to make calls, get messages, and surf the web, wherever you have WiFi! Seriously, ditch your cell phone plan and just use this! Alright, that might be a bit drastic, but this really is a great app, so go check out the free version and get the Pro if you end up liking it!
