The Timeline — See Your Entire Day as a Gantt Chart

4 min read

Pie charts and bar graphs summarize your day. The Timeline shows you the raw shape of it. Every app session rendered as a colored bar on a horizontal timeline, hour by hour. It is the closest thing to replaying your workday in fast forward.

The Gantt View

The Timeline page renders your app sessions as horizontal bars on a time axis. Each bar is color-coded by category — blue for development, yellow for communication, orange for coding, purple for browsing. The result looks like a Gantt chart of your actual day.

At a glance, you can see structure that summary charts hide:

  • Focus blocks — long uninterrupted bars of a single color mean deep work
  • Context switching — rapid alternation between colors means fragmented attention
  • Meeting gaps — empty stretches or communication-colored blocks show when meetings ate your day
  • Work boundaries — where your day actually starts and ends vs. when you think it does

Session Merging

Raw app tracking produces hundreds of micro-sessions per day. Checking Slack for 10 seconds between two VS Code sessions would clutter the timeline. The Timeline view merges consecutive sessions of the same app within a 60-second gap into single blocks, reducing noise while preserving the true shape of your day.

Stat Cards

Four metrics sit above the timeline: total tracked screen time, total app switches, your longest uninterrupted session (with the app name), and your most-used app. These give you the quantitative summary while the timeline gives you the qualitative shape.

Session Detail List

Below the Gantt chart, a scrollable list shows every merged session with app name, window title, time range, duration, and category indicator. This is your searchable activity log — hover over any timeline bar to jump to the corresponding session in the list.

The Timeline is my most-used dashboard page. Summary stats tell you what happened. The Timeline shows you how it felt. Check yours at xeve.io/dashboard/timeline.
