Hi:

Sage 50 is build for a Windows OS and does not work on IOS unless you use Parallels. I am not aware of any program built specifically for Windows OS that runs on an iPad.

just to chime in. If you can run parallels on your device you can get windows inside parallels and then get sage to work in there. It is slower than 'native windows on X86 PC-laptop' but it does work.   Otherwise if you have a remote desktop/RDS server with Sage on it, then you can connect to that from any device with an RDP client (this could include android tablet, ipad, chromebook - there is an RDP client for any modern device basically).  The assumption is that you have something similar to a keyboard and mouse to interact with the RDS/RDP session.   

this is probably not the answer you are looking for. but otherwise what you maybe need to investigate is a fully-cloud-web-app based accounting software that you like, has the features you need, and can work via web browser on any device.  (ie, that is not sage 50 for sure).
