We’ve got another great round-up of new and updated Android apps this week. Leading things off is Pinkberry, the frozen yogurt store which offers some handy rewards for loyal customers. We’ve also got the Google-owned Zagat which got rewritten from the ground up and went free. Also, a way to discover the history places around you, a better method of detecting precipitation via your Android device, and a new app to help you make free calls and texts across a non-cellular network.
Pinger: Text Free + Call Free (Free)
More than just offering free texting, Pinger now offers free calling, too. You can call any line in the U.S. and Canada including landlines and non-smartphones. Your friends don’t even need the Pinger app installed to receive a call. You get your own real phone number that you can use even if you don’t have a calling plan. Pinger capitalizes on data plans as a conduit to offer free calls and text messages, especially handy if your talk plan is shared or your minutes are running low.
