Core Problem: Users need a frictionless way to log daily actions and track their impact without overwhelming complexity.
Invariants for Success:
- Users can log actions in under 10 seconds.
- The feed clearly shows the relationship between actions and outcomes.
- The default view prioritizes today's activities.
- Reflection is optional and unobtrusive.
Must-Have Outcome of the MVP: A single screen that allows users to log actions quickly, view a feed of their logs, and see metrics associated with those actions.
