Testimonials & Reviews

"A fantastic app. Love the portability. Pros: Overall Great. Cons: Pricey upgrade."

- Firewardy, September 2011


"... A To-list and Task scheduler?, A place to keep all your contacts email/home addresses & phone numbers?, A calender and date planner?, An Event manager?, A place to keep and jot down random notes of your choice? You've got it all! And the best? It's all for free. Yes, there is a pro version, but it only affects advanced functions, like "Connecting to their server", "Spelling" and some forms of grouping. ... You will never get this many uses in one bundle. Most software will only offer you one function. Either Calender planning, To-list management, or a Diary. And that's for a cost, forget about anything free! ..."

"It's one of the best diaries/PIMs/organizers out there! (Even the free version!). I can"t believe that only a few people know about it. All photos copy paste in less than a second. The only thing you can't have in the free version are the Sub-groups, the rest is perfect. This is the most beautiful digital diary in the world! And very-very easy to use!"
