I played with a UI / UX for a smart thermometer iOS application. The concept for this app was to create an app where you could individually control the temperature of each room.
Changing the temperature would be done through gesture controls, where the user would receive visual feedback with the background color dynamically change as they move their finger up & down to raise or lower the temperature.
Blue/Green backgrounds for cooler temps & Red/Purple backgrounds for warmer temps.
The only other feedback they would need on this screen would be the amount of time it’ll take to reach their desired temperature.
