"i love your program."

- dollardonn, October 2013

"What was the biggest influence on your decision to purchase EfficientPIM? My answer: It's simple to use, very intuitive and has a fantastic UI. Please write down your comments on EfficientPIM. My answer: It will be nice to have a way to change the Font for the Calendar view."

- GUIDO, May 2013

"What's more, you can embed attachments and type in a personalized text message using the rich-featured text editor, which offers support for text customization options (font, color, size, alignment), emoticons, tables, as well as basic editing operations (cut, copy, paste, delete)."

- Softpedia, January 2014

"... I am a computer business systems analyst and programmer with 20+ years experience and have spent years downloading and evaluating many software packages. One deficiency in my collection was a really good PIM/Address Book that is NOT Microsoft Outlook, which is too big and slow for me. As I evaluated EfficientPIM, I became increasingly impressed with the speed, stability, and most of all intuitive user interface. Every time I dreamed up a feature, I usually found it or something close to use in EfficientPIM. ..."
