Single Adult Finance Manager

Hi guys
As a single adult, sometimes I feel crazy with my balance. Not less than thousand times I asked my self : "what did you do with your money? what did you buy today? why do you still have just 1$ now?...". And I'm too lazy to always bring pen and note book to write down whenever I spent money in one day. This situation become worse and worse since I start working, because, as you know, we have not only cash, but also savings balance. And I want an easy way to quickly note every time I spent some money.
So that I wrote this simple application. It took you just 10 second once time and help you manage your balance pretty cool.
Hope you guys like this.
If you have any idea or feedback, please feel free to contact me with feature I prepared in my app.
Have fun!
