UX/UI and Mobile App Design: Blip Energy

Blip is an energy company marketing a smart battery that can serve as a backup in an outage, requires no installation, and can power high energy devices while energy is expensive, then recharge while energy is cheap.



Design a companion app for the smart battery "blipOne" to set it up, monitor it, and control its functionality.


Prepare blip for its initial launch of blipOne via website improvements and mobile app design.

My Role

  • User interviews
  • Interaction design
  • Prototyping the app
  • Usability testing
  • Responsive breakpoints for the website

Defining the Problem

Blip's potential customers need a way to find information on the website that will help them choose whether this smart battery is for them. And once they own one, they need a way to control blipOne's functionality and track their energy usage.


The battery needs to be set up via a mobile app, with the option to be managed via the app or a web-based dashboard, based on user preference.

App Design


  • A general customer research effort doubled as a screener survey
  • I interviewed 7 of the 32 survey participants
  • I collected great stories of experiences with power outages, as well as specific needs and hopes for the product


I like to include specific detail even in my initial sketches to help determine how information fits.

Next I do some cleaned-up sketches of potential wireframes to show my team and get feedback.

Evolution of the design

Selected iterations of the app dashboard, from earliest to latest:

My Process

Here is a glimpse into my Figma file and how I iterate with wireframes.

I leave myself notes to explain the differences from one version to the next, and I move quickly, duplicating screens and moving elements around to try out different arrangements and styles.

I decided against icons because several of the concepts weren't easily conveyed by the simplicity of icons. They worked better inside a menu represented in words.

Mockups - Work in Progress

Using Figma's prototype feature, I took these screenshots in just a few minutes to get our stakeholders and potential investors excited about the app.

Testing the Prototype

I prototyped the onboarding and a brief exploration of the dashboard (limited functionality) so that we could test the setup process. Much was left to the imagination since it could not work with the physical battery itself. But we could test some important things.

I took notes during the first four usability tests. In only that short time, I saw a lot of patterns and was able to make several recommendations.

Some findings from this process:


At this point I prepared to leave the project for another opportunity. I made careful notes of where I left off to hand off next steps to my replacement. I truly fell in love with this project over the months I was involved. I hope to help onboard the next UX Designer for blip when they make their next push forward on launching the product.
