Study Timer & Subject Tracker
Focus with an accurate timer and track study time by subject, today and this week.
Start a focused study session
Choose a subject and use a stopwatch or a focused countdown. Today and weekly totals are saved locally.
Your subjects and study records stay on this device. Nothing is uploaded.
Today
This week
Study against a subject with a stopwatch or focused countdown, then see today’s and this week’s totals. Records stay in versioned local storage on your device.
Accurate after backgrounding
The timer derives elapsed focus from absolute clock timestamps, so browser throttling does not multiply or lose completed focus time.
Limitations
This v1 tracks focused time and simple goals. It does not sync accounts or provide streaks, heatmaps or calendar exports.
