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.
Risky Assumptions Worth Testing:
- Users will find value in logging actions daily without needing prompts or templates.
- The auto-attachment of metrics will be effective and accurate enough to encourage continued use.
- Users will prefer a minimalist design over more detailed analytics or features.
Leanest Path to Value:
Create a single screen with:
- A quick log section (step chips and text field).
- A compact evidence feed showing logged actions grouped by date.
- A simple empty state with examples to encourage first-time use.
- Keyboard shortcuts for fast logging.
This setup allows users to log actions and see immediate feedback, fulfilling the core problem while minimizing complexity.
