Testimonials & Reviews

"Perfect for my needs. Pros: User friendly. Nice format. Cons: None. Was exactly what I was looking for."

- rob69aw, October 2011


"Hello, I love your program EfficientPIM Pro: very functional, but it is not enough for full use there email client."

- ҧ֧ ݧ֧, December 2012


"... Everything about the program is both detailed and easy to use; for example, it's easy to create new events, but there's still a high level of customization, with settings for importance, recurrence, colored labels, flexible reminders, and even user-defined alert sounds. Contacts include fields not only for names and addresses, but for spouses, birthdays and anniversaries, hobbies, and even photos. ... 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. ..."
