Focus session logger — measure your deep work
Tracking how long you work tells only half the story; tracking how well you focused tells the rest. This logger lets you record each block of deep work with its duration and a quick quality rating, then shows your running totals — so you can spot which tasks, times and conditions produce your sharpest concentration.
How it works
After a focus block, add a session with three details: what you worked on, how many minutes it lasted, and a 1-to-5 focus rating (shown as stars) for how deep and undistracted it felt. The tool keeps a list of all sessions and rolls up two figures: total focused time, found by summing the minutes of every session and showing the result in hours and minutes, and your average focus score, the mean of all the ratings. It pairs naturally with a Pomodoro or time-blocking routine — log each block as you finish it.
Example
Log three sessions in a morning:
| Task | Minutes | Focus |
|---|---|---|
| Write report | 50 | ★★★★☆ (4) |
| Email triage | 20 | ★★☆☆☆ (2) |
| Deep coding | 90 | ★★★★★ (5) |
Total focused time = 50 + 20 + 90 = 160 minutes (2 h 40 m), and the average focus score = (4 + 2 + 5) ÷ 3 ≈ 3.7 / 5 — quickly flagging email triage as the weak spot.
