Done Diary is a simple diary app for recording what you accomplished today and giving yourself credit for the small things. It is not made to push you to do more. It is made to help you notice what you finished, what you kept up with, and the small steps you took today. You can record what you did today, things you want to do later, and daily habits. At the end of the day, you can also add your mood and a short note to gently reflect on your day. Your records can be reviewed in Days by month. Use the list or calendar view to look back on what you have been building over time. Recommended for people who: ・want to focus on what they did, not what they could not do ・want a diary that is easy to continue ・want to track habits and small actions gently ・want to end each day with a little more self-recognition Done Diary is not about trying harder. It is about noticing what you already did today. Keep small records, and look back on your everyday progress.
