Hot Phone app for iPhone and iPad

From time to time, there are new mobile phones / tablets being launched to the market. To be a trendy person, you must be eager to buy them so that you will have common language with your friends. To create and motivate your purchasing needs, telecom companies promote a lot of subscription plans for you to choose from.

To ease your decision of subscription, this App creates a comparison table for different plans from different telecom companies. By entering telephone retail price, subscription fee, pre-payment…etc, this App will derive 3 indexes:
1. cost per monthly rebated fee
2. cost per each MB of data
3. actual cost per month
The index of smaller value implies the better performance. After comparison, the lowest index2 and index3 will be highlighted in red.
