Google Docs

Whether for school or work, Google Docs is the perfect app to write and edit documents on your iPad. What makes Google Docs great is how easy it is to use and access on any device; you can create or edit documents in the cloud, and you’ll be able to share them with friends or coworkers in an instant.
What’s great is that anyone can open these documents, and all they need to edit them is a Google or Gmail account. It doesn’t matter if they’re using a Windows PC, Mac, Android device, an iPhone, or even some obscure version of Linux; they can still open and edit the file as they please with nothing more than a modern web browser. Not only that, but you can also export and share your work as a Word document or even as a PDF file.
Overall, Google Docs is a versatile, free, and powerful app you should have on your iPad and even on your iPhone.
