FlowHarbor

FlowHarbor helps you enter and sustain deep focus by structuring your work into uninterrupted task flows. Unlike conventional timers, FlowHarbor is designed around the psychology of flow state — once you begin, you move through a sequence of focus blocks without interruption until your work is complete.

CREATE TASK FLOWS
Define a task, set the number of focus blocks (2 to 6), choose block durations from 25 to 60 minutes, and add sub-goals for each block. FlowHarbor calculates your total session duration and displays a visual timeline showing your path ahead.

IMMERSIVE FOCUS MODE
When you start a flow, your screen transforms into a calm, animated abstract landscape. Colors shift gradually from cool blues to warm ambers as you progress through blocks — a subtle visual cue of your journey. The interface is deliberately minimal: no visible timer, no buttons, no distractions. Swipe up from the screen edge to briefly check your block progress, then return to deep work.

UNINTERRUPTED BLOCKS
Each block flows into the next without asking for permission. There is no pause button and no break prompt between blocks. This intentional design mirrors real flow state — once you are in, you stay in until the entire task flow is complete.

TRACK YOUR FOCUS QUALITY
FlowHarbor monitors session interruptions. At the end of each flow, you see a trajectory chart showing your focus quality across every block. A composite score reflects how well you maintained concentration. Add a personal review to capture what you accomplished and how it felt.

BUILD YOUR HISTORY
Every completed flow is saved locally. Browse your history by date, review past scores, and see how your focus capacity evolves over time.

PRIVATE BY DESIGN
FlowHarbor works entirely offline. Your task flows, session data, and reviews never leave your device. No account is required, no analytics are collected, and no permissions are requested beyond what the app needs to function.

Perfect for writers, programmers, students, researchers, and anyone who needs to do deep, uninterrupted work.
