Designed One Drop, a pool and hot tub chemical measurer that allows users to accurately test pH levels and calculate precise chemical dosages. When paired with its app, it reduces cognitive load by automatically adjusting calculations for different pool or hot tub volumes and chemical types—whether powder or liquid. The app provides step-by-step guidance, showing how much chemical remains to be added and confirming when the full amount has been applied.

Created product renderings in SolidWorks and designed the app interface in Adobe Illustrator.
