Project Time Machines 2.0

Find out when you'll really finish.

You say you plan to finish this project by June. Your own work habits say September.

14 weeks later than you planned.

Most of us guess short.

In a 1994 study, students already working on their thesis guessed they'd finish in 34 days. It took 56. A finish date picked by feel is usually wrong.

Buehler, Griffin and Ross, Journal of Personality and Social Psychology, 1994.

So PTM does the arithmetic.

The hours you say are leftdivided bythe hours a week you really workisthe date you'll finish.

No pep talks. Your own hours, and a date.

Hours left Free

Everything that's left, on one board.

Break the project into stages, and each stage into tasks small enough to sit down and do. Put hours on each one. PTM adds them up, so "almost done" turns into a number.

Start the timer from any task. The time you work is logged against it.
Worked without the timer? Add the time afterward. It counts.
One stage waits on another? Say so, and PTM holds it until the first is finished.

PTM 2.0 on a phone. The project is Write my novel, 208 days to go. Its board shows the first stage, Plan the rest of the novel, with 12 hours remaining and four tasks, each with a timer button and its hours. — PTM 2.0 on a phone: the first stage of a novel, with the hours on each task.

The date

A finish date that keeps up with you.

Every time you work, PTM logs the hours, and it keeps your breaks out of the count. Then it puts those hours to use. Every project shows three dates.

When the last two agree, you're keeping your pace. When they drift apart, you see it, with time left to do something about it.

Goal Date

The date you want. You pick it.

Hours left, divided by the hours a week you really work. It fills in once a project has a week on record.

The Pace screen in PTM 2.0 for the novel project. Goal Date 06-01-2027. Adjusted Goal Date 06-14-2027. Pro-Adjusted Goal Date shows a dash. Under True Pace it reads: a week of record, and this fills in. — The same novel in the app, on its first day. Two dates are in. The third waits for a week of work, then fills in.

Help with the work Pro

Stuck on a step you've never done before? Get help with it.

PTM Pro comes with a Project Agent. Ask it for what the project needs.

It builds your board with you. Describe the project. It asks a few questions, then writes the stages, the tasks and the hours. All of it stays yours to change.
It makes what the project needs. A scene planning sheet. A study plan. A cut list. Each one is saved with the project.
It looks things up. When a question needs research, it searches the web, reads what it finds and brings back the answer.
It reminds you. When a few days off is turning into a few weeks, on the schedule you choose.

And it already knows your project: what's done, what's left, and how much time you've really been putting in.

A chat with the Project Agent in PTM 2.0. The request reads: Make me a scene planning sheet for the middle chapters. The Project Agent answers that the sheet is ready and saved to the project, with an Open button. — One sentence to the Project Agent. It had already built this novel's board: eight questions, then 3 stages, 11 tasks and 126 hours.

The page the Project Agent made: Scene planning sheet for the middle chapters, with a bar showing the opening, the middle and the ending of a 60,000 word novel, and boxes to fill in. — What came back: a sheet to fill in, saved with the project.
