HandyHeater

Inspiration

Many times while taking a walk during winters while using our phones, we feel cold in our hands so we decided to make an app that can heat our phone so that our hands can stay warm

What our app does

It basically uses the power of your phone to heat the phone itself

What we used to build it

We built it using Kotlin and Android Studio.

Problems we faced

We had to figure out the best ways to heat the device quickly , and also only putting the CPU to work didn't help much, so we also had to put the GPU to work too

How we overcame the problems

For putting the CPU to work we are tracking the location of the device every millisecond using a service and the information is basically not going anywhere , also we are trying to calculate the exact value of pie in the background. Also to put the GPU to work we are using OpenGL to render graphics in the background

Accomplishments that we're proud of

We learnt how to do use OpenGL in the background , and we also learnt how to animate the UI in android.##But Most importantly we learnt how to code and build a product in a given time constraint and we are proud that we actually made completed our project!!

What's next for HandyHeater

We are planning to put safety checks to our application that it doesn't end up harming any device And we are also planning to make it dynamic so that the user can decide actually how much the device should heat
