This app allows you to send a letter to your future self. It has a simple design and is intuitive to use. You can set the letter to be delivered at a specified time, and it will notify you when the letter arrives. You can send a letter even years in advance. As long as you don't delete the app, you can receive it at any time. The app has a passcode lock, so you don't have to worry about anyone seeing the contents of your letters. (Some models are not compatible with this function. When I was in elementary school, I put my letters in a small can and opened it at my coming-of-age ceremony, which was fun, so I made this app. I would be very happy if you could give me any feedback or suggestions on how I can improve this app. Please download it and try the magical experience of receiving a letter from your past self!
