My First Android App 2020
I made an android app that user can simulate Julia set in 2020 May. So far, in 2022 December, more than 500 downloads have been recorded. I was interested in how far we could zoom in in mandelbrot set. I wanted to make a simulation of madelbrot set and push its limit on android device. Later, running a fractal on an andriod device was more expensive than my expection that I changed direction and built Julia set simulation instead.
What is Julia Set?
Numberphile did a great explanation video about Mandelbrot Set and Julia Set. Please check their videos.

Preview of my app on google playstore
It is a simulation of Julia Set. User can
- Drag around
- Change periods of RGB colors in sin function
- Toggle auto-color change
- Change real and imaginary value of C
- Toggle C value to be 0.7885*e^(ia) where a =[0, 2pi]
Challenges
- This app is developed using Unity Engine. I wish I could have made it without using an already existing engine. However, I did not know where to begin. The development process was highly dependent on The Art of Code.
What have you learned?
Installed audience by country
It is possible to build an app using unity. However, I lack fundamental knowledge in unity itself. Furthermore, optimization is an issue on the android platform. I targetted user persona to be my friends, but apparently there are more people who are using my app than my expectations.
