This app allows you to send a letter to your future self. It has a simple design and is intuitive to use.

(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!
