Testimonials & Reviews

"... As portable freeware, it runs as soon as you click its program file, with no local installation required. It is indeed an efficient, well-organized tool that is based around Events, Tasks, and a Diary as well as the typical Calendar, Contacts, and Notes entries, all controlled from a navigation sidebar. ... The Tasks feature is almost identical to Events and seems to be designed to let the user create his own distinctions based on personal preferences or needs. This program has some nice extras, such as a password generator and the ability to import holidays, diary entries, and other data."


"I think your software is an excellent and useful software that helps make people more comfortable and easier to write down their memories to keep their appointments and many other tasks."

- Mehdi, June 2012
