Testimonials & Reviews

"Hi, Thanks for the great program Efficient PIM."

- Jay Searls, January 2012


"I've just downloaded your Trial version of Lady's Organizer because I prefer its look to your Efficient PIM, which I've had for some time, & been very happy with."

"Love the software. How do I print a monthly calendar or a range of monthly calendars? Thanks much. p.s.We will add this feature in the future versions."

- Nick, January 2012


"... For many years I used the award winning 'Lotus Organizer' as my calendar/organizer, but Lotus is now defunct and this product is not compatible with Windows 7 which I now use, so I could not re- install it. Therefore I surfed Google for an alternative and found your 'Efficient PIM' which I downloaded and tried. It was just what I was looking for. It has all the features of Lotus and more, and is so easy to use. I love it and bought the licence the very next day. Unfortunately I have encountered a problem that I hope you can assist me with."
