A Mobile Wallet Price Tracker using the Chain.Link Price Feed and sends push notifications to users whenever the token pair changes
About
The problem it solves The is the only mobile app in the world where you can view Chain.Link Price Feeds and set push notifications to receive changes in Token Pair Prices! Users can now get "REAL TIME" information when the price of a token pair changes. Users can set high amounts and low amounts at which they will be sent a notification when the Prices reach such amount. The app works offline and displays the last updated Price that the user checked a token pair with information on the time. Thus, letting the user know how long ago it has been before they checked the time.
How it's made
Challenges we ran into I experienced challenges working with the Chain.Link Price Feed using JavaScript to return the token price pair in a decimal related format.
