Smart Bulb App​

UI/UX Design 2021

We bought cheap light bulbs from Alipay. Accompanied by the light blub is a mobile app where you can control the bulb's light intensity and color. This project mainly focuses on advancing the original Smart Bulb App from Tuya (with small adjustments to the Tuya Home control) to make the app more user-friendly, humanized, and convenient. I didn't like the idea of having all these circular slide bars, so instead my approach was to go with a more utilitarian design of simple bottom sliders and showcase the colors as changing gradient spheres.


  • The home/log in page is not necessary, nobody will sign up just to use a light bulb.

  • No need to connect to wifi, bluetooth connection is enough.

  • Slide bars are not suitable for finger sizes

  • Music page is confusing, remove it

  • Not enough contrast of colors.

  • Rename tabes to “Tones”, “Hue”, “Scenes”


  • Use gradient spheres to depict colors of light.

  • Reduce cognitive load by simplifying process of changing the setting of the lighting

  • Make sliders larger and add swipe feature to switch between brightness, hue, and saturation.

  • Make music section more accessible/user friendly
