Hi Russ! The iOS app for italki should be released within a few months. This will make using the community features easier for you. Your lessons will still take place over Skype, or you can find a teacher that can use Facetime which is a great program for iPad and iPhone. If you are learning Mandarin, make sure to download 微信 (weixin) The english version is called WeChat and you can get it for free in the App store. Wechat is what everyone uses to communicate in China instead of text messaging or calling. When you make Chinese friends, it will be much easier to keep in touch with them if you have a WeChat account! Happy learning! 加油！
