Chronello
Focus tracker · runs on your machine

A focus timer that
scores how focused
you actually were.

Pick a length, pick your breaks, start working. Chronello watches which window has focus, decides on-task vs off-task in real time, and gives you a productivity score at the end. The AI that does the scoring runs on your own computer, so nothing about your work leaves the machine.

Sessions, breaks, history, and scoring all keep working when you're offline.

What it does

A focus timer with a brain.

A regular timer counts down. Chronello also watches which window you're in, decides whether that counts as work, logs every distraction, and gives the session a score when it ends.

01 · On-device AI scoring

The AI runs on your computer, not ours.

Chronello classifies each window you visit as on-task or off-task for whatever you said you were working on, then gives the session a score out of 100. The model lives on your machine. Your window titles, app names, and notes never get sent anywhere.

02

Live on-task indicator while you work.

A green dot when you're in the right window, yellow when you drift, red when you're elsewhere. The counter for your current focus streak ticks up beside it.

03

Pick the length and the breaks you want.

Set a duration in minutes, then schedule a fixed number of breaks at set lengths, or leave the session open-ended and call breaks yourself.

04 · Session summary

A score, a focus-over-time graph, and a place to write down what worked.

When the timer stops you get the score, a graph of focus across the session, any milestones you hit, and two fields: a name for the session and a notes box. Save it or discard it.

05 · Insights and history

Every session you've ever run, searchable.

Filter by today, week, or month. Search by name. Open any session to see its full breakdown again.

06 · Milestones and streaks

Records that keep themselves.

Longest session, highest score, best day, current streak — tracked automatically and shown in the records tab. No setup.

A look around

The dashboard, and the session screen.

The dashboard is what you open in the morning: totals, average score, hours, and a trend chart. The session screen is everything else.
