This is a proposal i submitted for IWIC2015 - Indosat Wireless Innovation Contest 2015 - an annual CSR program by Indosat Ooredoo, mobile app development / ideas competition.
CALCULATHINGS, stands for Calculator of Things (too obvious :p), is a mobile app concept that helps user create their own calculator. The option are limitless, create your own button, put formula on a button, choose a color for the button and etc.
What this can be turned into? plenty! math formula calculator, cashier app, financial calculator, credit load calculator and etc.
2. Background Problem
Some business and education might
need special made calculator to fit their
needs, that current calculator can’t
deliver..
.. however, custom cashier system is
expensive for some low-mid enterprise
(UKM).
