One of the reasons why keeping your journal is a worthwhile investment is that you can improve your writing skills. Best way to get good at something is to do it more. Diarly has simple tools built-in into it so that you can track how much you write, and while writing, show how much of the target you already reached.
Writing Goals and statistics are available only for the time-line/diary entries. As notes are something you keep and modify over time - they don’t count in into the writing stats.
