Android Spectrum Analyzer App Enhancement

I have a new technology that turns an Android phone into a high-resolution comparison analyzer. I'm looking for a professional with experience in app development to adapt current Spectrum Analyzer apps to optimize the sensor/app combination.

We are unsure in what direction to take the project.
Equally unsure of budgeting or if we wish to enter a licensing arrangement.
All conditions negotiable


Requirements:
- Improved features of Spectrum Analyzer apps for Android
- Enhancing the user interface to a minimalistic design
- Improving the accuracy and processing speed of the app

Ideal Skills:
- Proficient in Android app development
- Experience with Spectrum Analyzer apps
- UI/UX design skills, particularly in minimalistic design
- Strong focus on accuracy and processing speed optimizations
