Track your hours. Trust the total.

Timesifier is being built: a timer and a weekly report for people who bill or answer for their time. You will start it when you start work, and by Friday the week will be added up, by project and by day.

A day as Timesifier will keep it: one timer, the entries it made, and their total.

One press will start the clock.

You will say what you are working on, choose the project and start. When you stop, the entry will be on the day with its start and its end. If you forgot to start it, you will add the entry by hand.

See where the week went.

Every entry will land in the week, under its project and its day. In the example below, read across for a project, down for a day; the longest bar is where the week went.

Example: a week, in hours and minutes by project and day.

Numbers you can show.

An entry will keep its start and its end, and a total will be the entries under it added together, to the second while the timer runs. When a client or a manager asks what Wednesday was, the answer will be on the page.

The anatomy of a working dayExample

The morning drawn here is worked in the rhythm of the Pomodoro Technique, Francesco Cirillo’s method: 25 minutes of work, a short break, and a longer break after every fourth stretch. The rhythm is the person’s. The timer will record what they did.

How it will work

  1. StartOne press starts the timer. It counts from that second.
  2. A stretch of focusTime feeds out as a strip, and its length is the time worked. Stopping cuts it off as an entry, with its start and its end.
  3. A longer breakAfter the fourth stretch, a longer rest. The rail is bare: a break is the time no entry covers.
  4. A short breakA few minutes between two stretches. Nothing is recorded for it, and nothing recorded is lost.
  5. The day, added upThe same strips, closed up end to end. The day’s total is where they reach on the scale: you can check it by eye.
  6. The weekEach day’s entries join the lane of their project. A project’s total is the length of its lane.
  7. The totalThe lanes are measured and added. That one number is what you bill from.
