FreqTimer
This is a small timer application used for running discrete trials in precision teaching and behavior analytics.
I developed it around 2016 as my first functional application. It came to be relied on by some. Unfortunately, mobile platforms are a bit of a moving target, requiring consistent maintenance and fees to publishing on mobile app stores. I decided to rewrite it as a web application to test WebAssembly. This way, it maintains most of the original functionality while being much more maintainable.
