Overview
Pomodoro Timer is a focus execution tool built for low-friction deep work. It keeps users in a clear work/break rhythm while remaining minimal enough to start in seconds.
Problem
Many timer apps overload users with settings or productivity gimmicks before the first session. That friction causes skipped sessions and inconsistent routine building.
Solution
The app centers a one-tap session start, deterministic focus/short-break/long-break cycles, and simple controls for pause, resume, and skip. Configuration is available but stays out of the main flow.
Architecture
A frontend-first app with a deterministic cycle state machine and local persistence for settings and daily counts. PWA capabilities (manifest + service worker) allow installability and stable behavior when connectivity is poor.
Key decisions
Prioritized reliability and clarity over dense dashboards. Kept the primary screen action-focused, with optional configuration and history separated from active timing.
Challenges
Handling timer consistency across tab backgrounding and mobile interruptions while keeping the UX calm and readable under long work sessions.
Outcome
A practical focus companion that demonstrates product restraint, state modeling, and offline-ready web app engineering.
