DecoDiary is a free diary application that allows you to record your daily life with timestamps, photos, voice recordings, and text. You can freely arrange the order of these elements and apply styles to the text. The timestamps can be customized with different colors, and you can also apply a pattern with a background color to enhance the beauty of your diary. The app allows you to categorize your diaries and easily find them. All photos attached to the diary are displayed in a list, making it easy to view them.

DecoDiary provides a lock number and fingerprint to unlock your diary. The diary data is automatically backed up to Google Drive and your device. The app supports English, Korean, and Japanese languages. However, the app does not have a subcategory and is listed under the Business & Productivity category.
