Testimonials & Reviews

"Cute and easy to use! Pros: Easy to download. Set up nicely to imput contact data. Has informed me correctly about upcoming appointments. I am finally organized! Cons: One weird quirk I don't like. It organizes according to the first name of contact rather than by last name. Can't find a way to correct it. Summary: It's free, it's cute and I like it!"

"I have your wonderful Efficient Software program. I love it, it is great."

- Bryan, September 2013


"... It includes a Calendar, Notes, Diary, and other features common to personal organizers, as well as some less common ones like password protection and a password generator. It has the same basic interface as virtually identical editions, with the exception of a pink-hued interface and the liberal application of hearts and bubbles to the program's skin. While it's not for everyone, plenty of ladies (and gentlemen) will find it a refreshing and fun change from the drab blues, grays, and what-the-heck-do-you-call-that-colors that dominate software today."
