This is a very useful app for some planning but it is a steep climb (think Mt Denali) to learning how to use it comfortably and I doubt I will ever get there. Syncing with your computer is a nightmare on wheels and the instructions offered will not get you there. If you like puzzles you may like app.
And one final point: if you inadvertently add a line and want to delete it, the developers of this app have made that about as difficult as ever possible. It can be done, but I challenge you to find out how. Come on guys, make this potentially very good app, just good!
