*2021-08-15, version 2.0.1*

Mình dùng app này thay thế app mặc định của iphone luôn vì tiện ích hơn nhiều, dễ sử dụng. 
Tuy nhiên sau bản cập nhật gần nhất đang bị 1 lỗi nhỏ đó là dấu ngăn cách thập phân ở bảng tính (dấu ,) và ở phần kết quả (dấu .) đang không khớp nhau, nên khi tính xong muốn dùng luôn kết quả cũ để làm phép tính tiếp theo không được đó ạ, mong là sớm có bản cập nhật fix lại. Cám ơn ng phát hành app 😄
