Relief is a simple diary app that focuses on writing calmly. Write down what you feel and blur in your daily life. ●Write down what you are thinking about When you are living your daily life, you may have fun, but you may also have pain. Writing down your worries and bothers will make you feel better, and writing down the things you enjoy will make you like yourself. ●Diary that grows from a seed However, even if you plan to look back at the end of the day, you will forget. In Relief, you can keep a short diary called "Seed". During the busy daytime, you can write down short notes as "Seed" and look back on them when you have time. ●Writing is important, looking back is occasional There are many beautifully designed diary apps, but it is more important to write down what is in your head than to look back. Usually, it is OK to just "write". Every once in a while, look back at your diary from a year ago or a month ago. If you are struggling with the same thing, it is important to you, and if you can put it in the past, you will realize that you are growing. ●You can write at night or in the morning Although most people think of writing a diary at night, you can do it in the morning because it is important to write down what is going on in your head. In fact, some people believe that you can forget about some things after you go to bed, so you can face what is important to you more easily in the morning. ●Sync with multiple devices As long as you are signed in with the same Apple ID, you can share your data with your iPhone/iPad. Your data is automatically backed up, so you don't have to worry in case of an emergency. ●Privacy Diary and seed data are stored in a private space on iCloud, managed by Apple and inaccessible even to developers. You can write your personal things safely. ---- Other Information Terms of Use https://comet-geometry-805.notion.site/1300783f45e84b23b0ab93007c4adb02 Privacy Policy https://comet-geometry-805.notion.site/864ca6a1e2ad4673907e8a9039389b5b Specified Commercial Transactions Law https://comet-geometry-805.notion.site/9f368c6f7dd5485fac54be0abbfdc183
