Focus

Productivity timer with ambient sounds. Side project for practicing microservices and desktop development.

What It Does

Pomodoro timer + ambient sounds + session tracking.

• Start 25min/5min/90min focus sessions
• Play rain, waves, or white noise while working
• Track sessions and see daily/weekly stats
• Everything runs locally

Tech

Backend: C# .NET microservices (Timer, Session Tracker, Sound Service) Frontend: Electron desktop app Database: SQLite Audio: NAudio for MP3 playback

Run It

cd FocusApp
npm install
npm start

App auto-starts all backend services.

Need: .NET 9 SDK installed

How It Works

Electron app talks to three local APIs:

• Timer Service (port 5004)
• Session Tracker (port 5179)
• Sound Service (port 5014)

Services are independent. Could be deployed separately.

Files

TimerService/          → Timer logic
SessionTrackerService/ → SQLite session tracking  
SoundService/          → Plays MP3s
  └── Sounds/          → Rain.mp3, Waves.mp3, WhiteNoise.mp3
FocusApp/              → Desktop UI

Notes

• Data resets on app restart (SQLite recreated each time)
• Need MP3 files in Sounds folder
• Backend terminal output visible when running

Built to practice microservices patterns and C#/JavaScript integration. Fully functional but not production-ready.
