Last week I had a reality check moment that blew me away. I usually provide simple and easy to use Excel solutions that performed complex calculations in the background. These files usually included all the bells and whistles of a well designed spreadsheets: arrays, VBA, named ranges, etc.

However, last week I delivered one of those solutions and it was widely rejected by my users. The only reason provided was that the file would not run on an iPhone. This was a wake up call to me to stop thinking of desktop and begin transitioning to smart phones.

This is the reason why I started this thread. If any of you can share tips with other users of what to avoid when creating Excel spreadsheets for smart phones it will be highly beneficial to lots of forum members.

Thank you all for your help.
