"Really like this app a lot and always looking forward the next revision with its new features. I have been happily using MacJournal since the beginning. Sometimes I even get up to using it half of the days which is a lot for me."

"This is a thank you for a superb product. I am writing more than I have done for quite some time. It is journal writing and getting my thoughts down in words. I love that I can specify different types of journals and make sub journals. It is so easy and everything is in one place. This is so wonderful and everything is dated. I really appreciate the convenience and ease of using MacJournal. Later I may take a look at your stuff for writers. Thanks again."
