Easy and practical
I needed an app just like this one to post in my own iCalendar rather than ad another calendar app. I use it for many things, one of them is to know and post cycles for the plants we grow in our patio and to post our cat birthday in its own "cat years". I love that the developer has added the option to write him/her a letter and make some suggestions, compliments, questions, etc.
