Don't use an entertainment toy for TeX. iPad is a very nice piece of hardware but it is only a consumer (gamer) device - not a full featured Computer. Its good for games and ebooks but I would never use it as a developer engine.
Why do you want to hurt yourself typing TeX on a virtual keyboard? If you consider to add a real keyboard to your ipad then you should better get serious and use a Macbook, Linux or Windows.
