Case Study // Public Product 005
Clarify
A complete Getting Things Done system for iPhone, from inbox to weekly review.
Product thesis
Built for a specific user, with privacy as product strategy.
Clarify implements the full GTD method instead of a generic task list. It supports capture, projects, contexts, next actions, weekly review, onboarding, and integrations with Apple Reminders and Google Tasks.
Audience
GTD practitioners and productivity-minded professionals who want the method preserved in a native Apple app.
Privacy stance
Task data is handled through native Apple storage and user-selected integrations rather than a proprietary task cloud.
Public proof
Live paid App Store product, version 1.31, with release documentation and app-store copy maintained in-repo.
