At the end of the day, you can rate your day with "maru", "batsu", or "sankaku".
A good day: ・・・・・Maru
A bad day: ・・・・・・Batsu
A so-so day ・・・・・San-Kaku
You can discover what words are associated with a good day or a bad day by writing the reasons in your diary. The criteria for judging a good day and a bad day change. The feature of this app is that you can notice the changes in the criteria.
For situations like these
When you feel like going on a journey of self-discovery.
When you want to be happier.
When you want to know what events are related to your happiness.

Thank you for using Penguin Diary.
Penguin Diary will end its service in February 2027. We are truly grateful to everyone who has kept their diary with us.
So you can keep writing, you can now move your diaries to our successor app, Triad AI Journal.
How to move your diaries:
Tap the notice at the top of the calendar screen
Tap “Export CSV” and save the file, for example to the Files app
Install Triad AI Journal, open “Switch from Penguin Diary”, and pick the saved file
Your dates, marks, and diary text carry over. Categories, emotions, and tags are not carried over.
After the service ends, you will no longer be able to view your diaries in Penguin Diary, so we recommend moving them soon.
Thank you so much for being with us all this time.
