Testimonials & Reviews

"What was the biggest influence on your decision to purchase Efficient Lady's Organizer? My answer: I was looking for diary software. For just a few dollars more I could get more! My friend said I deserved the Lady's version. ... The password manager and registration code manager is a great bonus! With all the software and passwords that a person has to manage, this will make it easy to keep up with it all! Please write down your comments on Efficient Lady's Organizer. ..."

- Joy Pierce, August 2012


"Some of the features disabled in this free version are: data sharing, organizing the information by group, adding attachments, spelling checker, card view support, and relating events, tasks, and notes to contacts."

- Software Informer


"... This means that, at 9.79MB, the whole useful program can be popped onto a USB drive or other portable device, allowing you to manage your contacts, events, and more wherever you go. The program's interface is attractive and intuitive, with a variety of color schemes to choose from. ... Although this free version of EfficientPIM alludes to some of the features that are available only in the Pro version, like spell check, this version of the software still offers a very impressive array of features. The program's Help file is well-written and thorough. ..."
