Time Tracker

Time Tracker grew out of my need to understand where my evenings were going. Already built apps felt too rigid and often require payment or subscription. So I built a multi-timer workspace that lets me track context switches without losing history.

Highlights

• Unlimited timers. Create timers for study, workouts, freelancing, or rest and run any combination simultaneously.
• Timeline view. A heatmap and stacked bar chart show exactly how long I spent on each category per day.
• Session notes. Each timer can capture a short reflection so I remember what I accomplished during that block.

Under the hood

• Next.js app router with server components renders timers even when the client reconnects mid-session.
• Prisma + SQLite when offline, with sync to PostgreSQL.

Simple helpers like these keep the business logic readable while I focus on UX experiments, such as how to display overlapping timers or how to summarize a week without clutter. This timer is now my go-to ritual check, and it has drastically improved how intentionally I spend my time.
