I require a simple Android App that takes uses APIs to perform a simple percentage calculation.
The app will display two distinct figures and a percentage difference of the two.
This app will alert the user when the percentage reaches a certain level i.e. absolute difference greater than 2%.
This level can be set by the user - to either 1%, 1.5%, 2%, etc.
The app will refresh once every 10 seconds to retrieve from APIs.
Simple interface will be enough, as this app is for personal use, not for store.
