## Story 003: Review focus history

**Persona:** Devon, 42, therapist, uses pomodoro to track whether his productivity habits are stable. He checks his session count weekly as a proxy for whether he is managing his ADHD medication and sleep well. He wants history he can actually trust (not fabricated stats) and review in a glance.

**Situation:**

Devon is reviewing his week on Sunday evening. He wants to know: How many sessions did I actually complete this week? Is the count trending up or down? Has my average session length changed? The answers tell him whether his baseline stability is holding.

**Need:**

As Devon, I want to see how many sessions I completed today, this week, and all-time, so that I can track whether my focus capacity is stable and adjust my schedule if it is not.

**Acceptance:**
- The app shows a dashboard with three numbers: today's completed sessions, this week's completed sessions, all-time completed sessions.
- I can tap into a detailed view to see session dates and lengths (the raw data).
- The numbers are accurate (they match what actually completed, not what was started).
- The history persists across app restarts and phone upgrades.

**Tier:** core

**Confusion-flags:**
- The difference between 'sessions started' and 'sessions completed' is real and matters for people like Devon who track their own patterns. I'm assuming 'completed' means the notification fired, but the team should confirm this is the right completion gate.
- All-time history is a lot of data to store on a phone. The Tweedles will need to design around this, but it matters to the persona. Should we ever delete old history? I don't know. Flagging for them.
