Start a focused study session

00:00:00

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.
