DepthWork: Deep Focus Timer

Most focus apps just count minutes. DepthWork measures the quality of your attention — built for ADHD minds, developers, and anyone who's tried every timer and still can't stay focused. Cal Newport called it deep work. We built the tool that measures whether you actually did it. Designed around peer-reviewed research on attention, habit formation, and flow states, DepthWork turns deep work into a system you can actually train.

WHAT MAKES DEPTHWORK DIFFERENT

Focus Depth Index (FDI) — a single 0–100 score that reflects how deep your focus really went, not just how long you sat there. Flow state detection — sessions that cross the ~25-minute uninterrupted threshold earn a rare Flow badge, inspired by Csíkszentmihályi's research. Distraction timing matters — interruptions early in a session cost more than late ones, modeling the well-known 23-minute re-focus cost. Goal completion bonus — set a micro-goal before each session — completing it adds a significant bonus to your FDI score. Focus fitness tracking — watch your focus score grow week over week as your sessions get deeper.

HOW IT WORKS

Set your intention. A short pre-session goal primes your attention before the timer starts. Focus without interruption. The app silently tracks session quality in the background. Get your FDI score. Completion ratio, distraction decay, timing penalty, and goal completion combine into a meaningful number. Build the habit. Your FDI trend, flow badges, and weekly progress chart show how your attention actually improves — not just whether you showed up.

ACHIEVEMENTS THAT MEAN SOMETHING Every badge marks a measurable point in your focus development — backed by the same research that powers the FDI score:

First Synapse — your first focus session Myelin Builder — one week in, your routine is taking shape Habit Encoded — three weeks of practice, focus starts to feel automatic Neural Architect — one month in, focus is becoming part of who you are Flow Native — six months, flow sessions are a regular part of your week Zone Entered — your first fully uninterrupted session

THE RESEARCH BEHIND IT

23-minute distraction recovery (UC Irvine attention research) Repeated, deliberate practice as the foundation of habit-building Goal completion as one of the most reliable reinforcement loops Strategically timed breaks to sustain attention Flow state thresholds drawn from Csíkszentmihályi's work Pink and white noise at low volumes to support sustained attention

A NOTE ON THE SCIENCE DepthWork is informed by widely cited attention and focus research, but it does not measure your brain directly — there are no EEG sensors or neural readings. The Focus Depth Index is a behavioral score derived from your session activity (interruption timing, goal completion, session length, and distraction patterns). It is not a medical device and is not intended to diagnose or treat ADHD or any other condition.
