Deep Focus

Task Management protocol utilizing biometric feedback to optimize developer state.

What It Is

Deep Focus treats attention as the scarcest resource in software engineering. It pairs a deliberately minimal task protocol with passive biometric signals — heart-rate variability, session cadence, typing rhythm — to learn when you are actually in flow and when you are merely at the keyboard.

The output is not another productivity graph. It is a protective layer: notifications held, tasks sequenced to match your cognitive state, and honest data about the conditions under which your best work happens.

By The Numbers

31%. Avg. context-switch drop.
2.4x. Flow-session length.
0. Cloud dependencies.

Key Features

State-Aware Sequencing

timeline

Orders the day's tasks against your measured focus curve — deep work when you are sharp, chores when you are not.

Signal-Informed Holds

notifications_paused

Detects fragmentation early and quietly defers non-urgent interruptions until a natural break.

On-Device Inference

lock

All biometric processing happens locally. Raw signals never leave the machine.

FAQ

Which wearables are supported? add

Anything HealthKit exposes — Apple Watch primarily. Desktop signals (typing cadence, app focus) work without any wearable.
