## Story 004: Review weekly and all-time history

**Persona:** Priya, 29, a researcher who believes in data-driven self-improvement. She logs her pomodoro sessions weekly to see if her focus capacity is improving, and she wants to spot patterns (days when she completed more, times of day when her sessions are longest).

**Situation:**

It's Friday evening. Priya wants to see how many sessions she completed this week compared to last week. She also wants a longer view: has her focus capacity improved over the last month?

**Need:**

As Priya, I want to see my session history for this week and all-time, so that I can track trends in my focus capacity and identify patterns.

**Acceptance:**
- The app shows a 'This Week' view that displays total sessions completed in the last 7 days
- The app shows an 'All-Time' view that displays total sessions completed across my entire history
- Each view shows a count and ideally a simple visual (bar chart, line graph) showing sessions per day
- I can tap into a day to see the sessions I completed that day (time started, duration, whether completed)

**Tier:** enrichment

**Confusion-flags:**
- Should 'all-time' include only the last 90 days, or truly all-time? Storage and UI complexity differ significantly.
- Does Priya want to export this data for analysis elsewhere, or is the in-app view sufficient? This is a known-unknown.
