Testimonials & Reviews

"Efficient Software's personal organizer comes in several versions, including freeware editions that offer most of the functionality but fewer features than the full versions. There are also versions optimized for men and women, Efficient Lady's Organizer Free and Efficient Man's Organizer Free. It's the same program, except that the ladies' version is decorated with pink hearts while the men's version is skinned in bolder, starker tones. Sure, it'd be easy to joke about gendered software, but at least there's a choice that doesn't involve a default theme that looks more like a bank statement than your life, organized."

- CNET


"... What was the biggest influence on your decision to purchase EfficientPIM? My answer: It was exciting and easy. I have been looking for a PIM for weeks and it took me a short time to decide about this one! 3. ... Also putting a note on the desktop keeps a to do list in sight. The only problem I have is it would be nice to have a pop up reminder for tasks and appointments. I have the sound off on my computer so the alarm doesn't help."
