This is a listing of the Apps that I use continually and that you might find useful. This first appeared in February 2013 and just four months later needs an update. Apps at the top of their group are most useful, I find, but that is personal. Text in red indicates an addition to the listings. Several links have been added to articles about some of the apps.
All of these are found in the Apple App Store. Most are free. Some of these apps are offered free periodically through an app called AppsGoneFree!
If you have any comments enter them below and I will answer by comment.
These apps make it easy to work wherever the mood takes you.
