We have just downloaded an awesome program that is available on both iproducts and android: Voxer. Do you use it? Its like a walkie talkie program. You can chat or leave a voice message which then can be replied instantly or when they get back online. There are other programs like FaceTime which are similar plus can have video but they do not work well with slow connections. Voxer works really good with a slow connection. Its awesome hearing the voices of your family and friends. There is a Korean app out there that is similiar as well; it is only voice.
