Spare Phone - Make and receive VoIP phone calls over WiFi!
Phone calls without using cell phone minutes!

If you follow the steps in the apps built-in 'setup wizard' you'll be able to make and receive 100 percent VoIP calls over WiFi or 3G/4G/LTE mobile data with zero cell phone minutes used! If you need any help I would kindly request that you contact me via email before leaving negative feedback as I actually take pride in this app!

Note: This app will be migrating away from solely using Google Voice mid-May(update: new version is now available). Incoming Google Voice calls will still be able to be handled by the app and the upcoming app update will guide you through the simple process. Outgoing calls will also be possible via Google Voice in addition to calls to other users of the app and toll free numbers will be included in the update too. The update offers great enhancements to the call quality as the app will now use a much improved audio codec. And many other exciting features are still in the works.

Some comments from users:
"So easy [...] Asus prime was blown away on how simple it was"

Frequently Asked Questions:

1.) Does this use my cell phone minutes?
No, Spare Phone uses your wireless network connection for calls. You don't even need active cell phone service to use this app. Note: If you are not using a WiFi network connection you will pay for your cellular data usage.

2.) Is this a simple callback app?

Yes, Spare Phone will enable your Android tablet to place and receive calls. It will also work with Wi-Fi only tablets too.

    I understand why the changes needed to be made, but usability is now awful. I would much rather have an older version of the app if available (and as a paying customer, I really would like to not have to download it from some virus-ridden apk site). The average user that uses this app wants to have a seamless GV experience, and this is very far from that. In order to make a call, I have to: 1.

    This app used to be good when it connected straight to google voice. Then voice said they were changing the rules and the developer got scared and rewrote the app. BTW, as I write this you can still access google voice the same way as before. Now this app works sort of when on wifi, but when on cell service (3G) it doesn't work at all. Google tries to call but the phone does not ring. If it does,

    My phone just updated itself today, apparently to the new Android KitKat -- now none of my google voice apps work at all!!! Spare Phone went from a reasonably good phone app to some weird thing that just takes you to the google voice website and then doesn't work. What the heck happened? I am so confused!

    I like how it works. Sound is good. If it makes a coin drop sound it means that the other persons line is unavailable, or its not connected to the internet correctly. If it not connected correctly reset it and it will work again.

    The reason why I bought the app in the first place is because it was foolproof fast setup. Ain't nobody got time for that. I'll just getta real phone l
