Description

Focus Flow is a clean and distraction-free Pomodoro app designed for deep work sessions. It combines time tracking, task management, and focus scoring into a single lightweight experience. Built to be fast, intuitive, and minimal, it helps users stay in flow without unnecessary features or clutter.

Tech Stack

  • Frontend: React 19, Tailwind CSS
  • Language: TypeScript

Key Features

  • Smart Pomodoro Timer — Automatically cycles between focus and break sessions.
  • Task Management — Add, track, and auto-cycle through active tasks.
  • Focus Metrics — Tracks focus score and distractions based on pause events.
  • Skip Break Option — Lets users jump back into work instantly.
  • Resilient Logic — Prevents timer from starting without active tasks.
  • Lightweight & Minimal — Optimized for speed with minimal dependencies.
  • Session Alerts — Plays a sound when a session ends to keep you on track.

Challenges & Solutions

1. Keeping Timer and Tasks in Sync

Challenge: Maintaining accurate state between the timer, current task, and session type without drifting or mismatches.

Solution: Used useEffect with controlled setInterval hooks, isolated work/break logic, and guard clauses to handle edge cases such as task depletion or manual timer skips.


2. Preventing Logic Breaks During Rapid User Actions

Challenge: Users could pause, skip, or end tasks in quick succession, sometimes breaking the session state.

Solution: Implemented a state-lock mechanism that queues state changes and only applies them at safe update points in the timer cycle.


3. Designing an Intuitive Focus Scoring System

Challenge: Creating a scoring method that encourages consistent focus without being punitive.

Solution: Calculated scores based on completed Pomodoro cycles and deducted points for distractions (pauses), giving users a tangible metric for improvement.


4. Balancing Feature Set with Simplicity

Challenge: Avoiding feature creep while still making the app genuinely useful.

Solution: Focused on core Pomodoro principles, implementing only the most impactful features first and leaving advanced analytics for a future release.

What I Learned

  • Managing complex timer state and side-effects in React with hooks.
  • Designing robust user interaction handling to avoid race conditions.
  • Creating lightweight UI flows that feel instant without overengineering.
