Testimonials & Reviews

"EfficientPIM is great and I use the portable version every day. Right away really indispensable. Very nice too that it's possible to pay via iDEAL."

- daniel, January 2014


"Love it...easy to use, password protection--keep track of everything in one place."

- abone, June 2011


"When we are talking about a software of this kind, the privacy of the users is a very important aspect that the developers of EfficientPIM Free did not take lightly. The programs will help you ensure the safety of your data with the help of a password that will be required each time you try to launch or restore (after it has been minimized) the application."

- Softoxi


"What was the biggest influence on your decision to purchase EfficientPIM? *My answer: *It has everything I need, in one package! I also love that you have a portable version for my flash drive. Please write down your comments on EfficientPIM. ... The only thing I can find wrong so far is that my desktop notes do not ever show up on my desktop. Is there a way to fix this?? I hope this program works as well as I think it will!"
