Protect the hours that move your work.
Set a few weekly targets, show up for 100 days, and watch focused work become a habit. Zaphiri tracks the days, the hours and how it felt.
Why it slips
Focus is scarce. And it breaks easily.
You only get a few hours of truly deep work a day, and every interruption costs more than it looks. Without a plan to protect those hours, the urgent work takes them.
What a focus habit needs
Four things that make deep work stick.
- 01 Targets you can actually repeat. Ambitious goals for one week tend to collapse by the next. In Zaphiri: Pick Gentle, Steady or Serious, or set your own. Changes start next Monday and never rewrite past weeks.
- 02 A defined experiment, not a vague resolution. "Do more deep work" has no start, no finish and no review. In Zaphiri: The 100-day experiment starts on a Monday, tracks whether you show up, and on day 100 shows what you achieved, asks what you will try next, and starts the next round in one tap.
- 03 Feedback on days, hours and how it felt. Hours alone miss whether the focus was real. In Zaphiri: Three weekly rings: Days, Hours, and Flow from a quick 1 to 5 rating after each session.
- 04 One change at a time. Changing everything at once tells you nothing. In Zaphiri: Optimize my Deep Work shows how to arrange your week from your own sessions, then offers one earned step with a check-in four weeks later.
The ideas behind it
Built on two books we use ourselves.
“A deep life is a good life.”
What we took from it: deep work is a skill you train on purpose, in protected blocks. So Zaphiri flags your Deep Work tasks, protects the time and counts the hours.
“I will [action] for [duration].”
What we took from it: treat change as an experiment with an end date, not a resolution. Your pact in Zaphiri: I will do Deep Work for 100 days.
The 100-day experiment
Pick a level, then show up.
Judged on showing up, not a perfect score. It starts the following Monday, so you begin with a clean week.
- Day 1 Flag your Deep Work tasks and track them
- Week 1 Your first weekly score
- Week 4 Your first earned step up
- Day 100 Plus, Minus, Next: keep, raise, or go again

Optimize my Deep Work
Shape your week. The targets follow.
Zaphiri looks at when your Deep Work really happens and tells you what to change: start your Peak window earlier, tighten it, or add a second one on the days it runs late. Each idea comes with the evidence from your own sessions.
When a week like that keeps working, Zaphiri offers the next step: raise one target by a notch. Nothing changes until you choose it, and it checks in four weeks later.
On your phone
Your week, back every week.
Review shows your Deep Work, finished tasks and best days in one place. The weekly recap arrives as a short push on the day you review your week, so you see where your focus went before you plan the next one.

A year of Deep Work
Small weeks add up to a big year.
Try your own numbers. A few protected hours a week turns into weeks of focused work by the end of the year.
