The long focus
After 90 minutes of deep work, Jambu suggests a short reset so your focus stays sharp.

Focus that

of you.
Jambu learns the shape of your workday from context alone — how long you've been going, when you stopped — and offers a gentle care moment when a pause would genuinely help.

Care moment
Afternoon focus
Active session · 2h 24m
After 2h 24m of continuous work, your rhythm usually dips here. A five-minute stretch would feel good — just a gentle nudge.
The problem
Tools track everything. Context is the part nobody has.
Time trackers log every tab. Focus apps count every keystroke. Then they hand you a dashboard of hours and leave you to work out what it meant — more data about your day, and still no one noticing that you've been at the same screen for four hours.
Jambu goes the other way. It watches almost nothing, and asks what that little tells it about your rhythm.
What a typical tracker keeps
- Every URL you visit
- Page titles and content
- Keystrokes and clipboard
- Screenshots of your screen
- App-by-app activity logs
None of it tells you why you're still at the desk. That's the part worth knowing.
How Jambu works
It observes context, then cares — quietly.
01
Observe
Active sessions, inactivity, and session length — signals only. Nothing you type or read is seen.
02
Understand
Over days, Jambu maps your real rhythm — when you focus, when you stall, when you're done.
03
Care
A timely, minimal nudge — a stretch, a break, or a quiet “you're done for now.” No guilt, ever.
A typical workday
Three moments, start to finish
Tall bars are sessions, flat ones are idle time. No page, no title, no text.
Observed
notes.example active since 09:04 · no idle since you started
Understood
Your weekday deep-work window opens around 09:00. You're in it.
Care
Nothing. No nudge is the right care moment here — Jambu stays quiet.
Never stored: the document title, the words you typed, the tab you were just on.
Care Moments
Interventions, timed to your day.
Gentle, dismissible, and always yours to snooze or silence.
The quiet stop
When your evening routine signals it's time to wind down, it offers a soft close — not an alarm.
Why now
Your usual close time, three days running
The drift check
Long inactivity at your desk? A friendly “stretch, breathe, come back” — nothing more.
Why now
11 minutes away from an open session
Hover or focus a card to see the single signal behind it. That's all Jambu works from.
Patterns, over time
It learns your week, not your words.
Give it a fortnight and Jambu starts to see the shape of your days — the 9:30 block that always works, the Tuesday evenings that run too late, the Sunday that stays quiet.
Nothing about that map is fixed. Every pattern it forms is one you can pause, correct, or erase, and none of it is built from what you were looking at.

Your data, your call
Take a copy of everything Jambu holds, or ask it to forget. Both happen in one tap, and both are final.
A plain JSON file — preferences and pattern summaries. Nothing else, because there is nothing else.
Deleting is immediate and permanent — no “we might keep a copy for 30 days”.
In the app
A quiet surface, not a dashboard.
No streaks, no league tables, no red numbers asking for an explanation. One calm view of where your day is going, and the two buttons that matter.
