Testimonials & Reviews

"Remembering all task, event, appointments are difficult because of hectic schedule and work load. We tend to forget some of them and that has negative impacts on the relationship. You can eliminate this failure by using Efficient Calendar. It acts as your scheduler, planner and reminder. It has multi-language support such as English, Croatian, Czech, Finnish, French, German, Norwegian, Portuguese, Russian, Simplified Chinese, Spanish, and Traditional Chinese."

"EfficientPIM is a convenient personal information manager. The ease to use, lots of interesting features, a nice design are just a few features which make this software a valuable office tool and not only."

- SoftSea

"Efficient Man's Organizer Free Portable breaks down this way: it's an efficient personal organizer designed for men that's totally portable and totally free. Portability is a key asset in a personal manager since a tool that's chained to your desktop obviously can't keep up with you when you're not at your desk. Efficient Man's Organizer is compact enough to run from a wide range of storage media and portable devices, yet it still offers a full set of features."
