This app allows you to record daily events, your responses, and the results on a single card. I believe it's important to keep a record of your decisions and their outcomes. The words you write down in this app will surely serve as some kind of guidance or help when you're unsure of a decision later on. Use it as your own "adventure log." [Features of this app] Record unlimited cards throughout the day. A single card allows you to record two parallel entry fields and two date settings. You can also mark specific cards. You can also record images of your choice in each of the two entry fields on the card. To protect the privacy of your recorded information, you can set the app to require a PIN to access. You can choose from 10 different card colors to help you categorize your content. The text search function allows you to quickly find and display matching cards. You can easily review past records from the calendar. Your recorded data can be transferred using iCloud, even if you change devices, ensuring long-term use. Recorded data can be viewed and processed as CSV data using software such as Excel. The app is designed to keep its size small even with continued use. You can also use it as a diary, idea notebook, or to record movies you've seen and your thoughts about them. There are major turning points in your life, such as choosing your preferred school or getting married, but even if you don't have any major events, you probably make many small choices every day. Even those small events may actually have a major impact on your life later on. Look back on your day and think about what happened today and the actions, choices, and decisions you made. We would also like you to keep a record of the results and lessons learned at a later date. We are sure that these records will be useful to you in the future. Each card will accumulate as experience points for you. One option is to download this app. We would be happy if you could let us know the results of your actions at a later date.
