He can download Librelink app it is same like reader. He must be carefull because selfphone can kill sensor. Its happened to me and my sensor was after two days dead.If you want better knowledge of what your blood sugars are doing and can afford it....definitely. It's a real eye opener when you first get it. I think you can download an app for an android mobile so you can use your phone as a reader which will save £50 or so. No use for an iphone, knew I should have stuck with the galaxy.....
