3 tap 300 is up on itunes
This is the first app I have released. A free simple tool to check whether a iPhone contact is on the same network as you. letting you know if you will be able use carrier exclusive benefits such as free minutes to call them.
In New Zealand there is a free txt Number 300 which you can text a cellphone number to and a response is sent whether a number is on the network (as in the same network as you). The user is presented with a table view of all the contacts ordered alphabetically. Upon selection it loads up a text messaging window with a filled out. with the user just having to push send. The user then wil receive a SMS from 300 with the result.
you can find the app on iTunes http://itunes.apple.com/nz/app/3-tap-300/id460031165?ls=1&mt=8
I’ve also released the source code up on github https://github.com/mmmbiscuits/threeTap300
