---

-Happy Diary's Key Features

-Record Positive Memos
Easily record the happy events and good things that happened today with simple text.
Forget about negative emotions for a moment and focus entirely on the positive!

-Attach Photos
Not just words, you can also save your favorite photos together. Vividly preserve those happy moments like a beautiful landscape or a delicious meal.

-Look Back with the Calendar
The calendar screen lets you see at a glance when you made a positive record. Enjoy the pleasure of watching your small daily joys pile up on your calendar.

-Daily Reminder Notifications
"Let's record the good things that happened today!" - A daily notification gently supports your habit of keeping a diary.


There are so many "joys" hidden in your everyday life that you just haven't noticed yet.
Why not start a new habit of collecting positive memories with Happy Diary?


How is this app different from others?
Easily record the happy events and good things that happened today with simple text. If you enjoy the gratitude-focused approach of the 5 Minute Journal or the mood-tracking interface of Reflectly, you’ll love how Happy Diary keeps your focus entirely on the positive!

Not just words—you can also save your favorite photos. Vividly preserve those happy moments like a beautiful landscape or a delicious meal. It’s the perfect visual companion to your self-care routine alongside apps like BetterMe and Ahead.

The calendar screen lets you see at a glance when you made a positive record. Much like the progress tracking in MindDoc or Finch, you can enjoy the pleasure of watching your small daily joys pile up over time.

"Let's record the good things that happened today!" — A daily notification gently supports your habit, acting as a supportive digital friend similar to Wysa or Headspace.
