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

**Persona:** Jordan, 26, a student preparing for exams. Jordan uses the pomodoro app to build study stamina over weeks. Seeing the upward trend in sessions completed motivates continuation.

**Situation:**

Jordan is in week 3 of using the app. They want to see whether they're actually studying more than last week, not just how much they studied today.

**Need:**

As Jordan, I want to view my session history for this week and all-time (e.g., sessions per day, a total count), so that I can see whether my focus stamina is improving over time.

**Acceptance:**
- A 'History' view shows sessions completed per day for the current week
- The same view includes an all-time total or a toggle to view all-time trend
- The view is readable at a glance (not overwhelming detail)
- Jordan can see dates and session counts; the exact format is flexible

**Tier:** core

**Confusion-flags:**
- What's the most useful way to display a week's worth of data? A table? A simple bar chart? Should users customize this?
- Should 'all-time' include breaks, or just sessions?
- If Jordan hasn't used the app in a few days, should missing days be visible as 0, or omitted?
