Fieldnote
A calm journaling app for field researchers, designed from first sketch to App Store launch in five months.

Fieldnote's founders had a powerful idea and a cluttered prototype. Researchers loved the concept but found the app stressful to use in the field, with one hand, in bad light.
We ran two weeks of diary studies with twelve researchers, then cut the app down to three core actions: capture, tag and find. Every screen was designed for one-thumb use and high contrast outdoors.
I built a small token-based design system alongside the screens so the two engineers could ship quickly without waiting on handoffs.
