A new calculator for smart devices designed to help you do your calculations easily and efficiently. The calculation formula is displayed in handwriting style, which is more intuitive. It's super fast and the results are presented instantly.

Hello Product Hunt! In order to make daily calculations more efficient and convenient, I developed this calculator. The smooth computing experience and the fit UI design allow you to switch from the system calculator without feeling. Also, I did a lot of optimizations to make the computation more efficient. For example, formula display, multi-keyboard switching, one-handed mode, automatic save, undo, etc. Actually I'm not a full-time programmer, I'm a mechanical engineer interested in program development. I would like to share some of my thoughts with you. Looking forward to any of your comments as well.
