XMIND is a mind map app available for all major notebook computers and all major smartphones. You can use the app with the defaults and get good results after a few hours and very good results after a day. There is a free trial period.

I consider this app to be the #1 choice for beginners and intermediate users. Most users of mind maps will find it does a great job and have no need to move up to the two more advanced apps available for expert users.

I also find that XMIND by default produces mind maps that communicate very well with other mind map users.

You can click on the mind map if you want to expand it.
