Log in name

I started using WordPress.com and created a log in name of Palmstead. I created a blog and did very little work on it. I later added the WordPress app for Ipad. I went in a logged in under Palmstead and some how I have a new profile that has created a different web page development. So now I have a much more developed site on the ipad app version. How to I get the on line version to equal my ipad app version.
