Just been on the Apple App store and theres a few DIY apps with material calculation etc and decent tutorials but 'm not sure what to get.

Has anyone else ever downloaded any of these apps, and if so were they any good? I'm starting to renovate my new house and its got no internet so I'm looking for something that covers a lot of material without a net connection to help me out a bit.

So far there's DIY DO IT which looks the most promising and a few others that I cant remember.

Any opinions welcome, cheers

Dave
