Sick Days

A symptom tracking app that began as an "I'm sick" or "I'm healthy" toggle with graphs.

In short

Sick Days began as a hackathon toggle app and sat neglected for most of 1.5 years, yet it already ranks first for "sick days." Its ASO audit cut 600 keyword ideas to 200 and chose 11 focus terms for title and subtitle. A Spanish Mexico localization served as a second keyword slot. Lesson: check who ranks, compare two keyword tools, and test paywall and pricing changes.
