Wanting to know if there is an IOS version/viewer available? 
Not here.
But there are a couple apps in iTunes.
OOReader.
It reads LibreOffice documents.
No editing.
Office 700 can do editing
May be others. Take a look there.

Thanks for the “heads up” : )
While there is no version of LibreOffice available for iOS yet, there are quite a few apps out there that support viewing documents. While being far from fully featured those apps have the benefit of a much smaller size. Depending on what you are aiming to do exactly, that might be enough until an official version is released in the future.
We recently launched an iOS version of our popular Android document viewer. Check it out on the App Store.
Application: OpenDocument Reader (free/ad-based)
