Testimonials & Reviews

"One if not the best and most complete PIMs out there. Pros: Task and events have repeat and alarm function; Can relate to contacts; Contacts show both events and tasks in one place or separably; Can be portable; Has everything including sticky notes ETC. Cons: Would be great to have mail as well but for the price may be asking a bit much. Summary: One of the best I've ever used and I've tried a lot over the years and if u r wondering i did pay for it lol."

"Just the Planner I was looking for! Pros: Great Calendar, allows you to make appointments on specific days of the week. Cons: Allow displays times in 30min increments. Would be nice if would allow you to type in your own times ...or had 10 or 5 min increments instead. Summary: Very easy to use and was just what I was looking for."
