Monthly Motion: How we built AMPY+

Posted by Tejas Shastry on Oct 22 2015

We’re pushing lots of big red buttons these days, and today is a gigantic one — our free, standalone smartphone app, AMPY+, is now live on the Apple App Store and in an Android public beta.

When we launched our Kickstarter campaign last October, we promised our backers we would build a companion smartphone app that tracked the calories they burned and the battery life they generated with AMPY MOVEs. It sounded simple enough – until we realized one thing: The battery life you generate with the device depends on how much you move and how you use your phone.

To give users an accurate experience, we accomplished something that no other app has done to date: We can predict how many hours of battery life a person would use in one day (spoiler: everyone uses their phone differently on different days of the week). We did this through the Battery Life Forecast – a dashboard of insights saying when your phone will run out of power and how long to charge it to get more juice.

We ended up building an app that changes how you stay charged, and realized AMPY+’s prediction algorithm was useful to users with and without an AMPY MOVE. With that, we decided to shape the entire AMPY+ experience around the Battery Life Forecast.

 

DESIGNING A NEW USER EXPERIENCE AROUND CHARGING 

Our first ideas around how to represent battery life centered around one concept – hours. For years, people had to figure out what a certain percentage meant on their battery meters (30% means something different on a Friday night compared to a Tuesday afternoon) . Now, users' battery life is in a relatable unit of time, and what better way to represent time than a circular clock?

 

We learned users wanted to know how long their phone would last and how long AMPY MOVE could extend their battery life. These were two separate measures of time, and naturally lent themselves to two separate clocks, and more colors.

 

Thanks to continuous feedback from beta users, we continued to add information to the insights at the bottom – a charge timer to help users know exactly how long to charge for to get through the end of their day, insights about their busiest day of the week, and notifications of exceptionally high usage. Our precious screen real estate was getting overloaded, so we looked at other apps to see how they handled these issues, and the answer came to us: A feed (Buzzfeed, Facebook feed, Twitter, you know the drill).

Feeds allow you to focus on one piece of content at a time before scrolling down to another. After numerous iterations, we landed on a design that allows us to give users all of the information we wanted.

We kept several of the elements from before – the circle for the prediction clock, the buttons for the AMPY MOVE LEDs – but added a number of visual interest to the Battery Life Forecast.

 

In just 6 short months, we had incorporated the feedback of users from around the world to build a smartphone app that truly redefines how you stay charged.
