Q: My chair is an app I use on my Ipad and I can no longer out this program

Your chair is an app?  You'll need to repost your question, because it doesn't make any sense as it is.

Are you talking about this?  https://itunes.apple.com/ca/app/mychair/id376771196?mt=8

If it's an app you purchased, see this:  http://support.apple.com/kb/HT2519

And btw, this has nothing to do with icloud.
