Active-time tracking
Per tab and per site, second by second. Background audio is counted separately, so totals never exceed real time at the screen.
100% local · open by design
See where your browser time really goes.
TabStyr quietly measures active time per tab and site, then turns it into a calm dashboard — trends, an activity heatmap, focus scoring, and gentle stale-tab nudges. Every byte stays on your device.

What it does
Everything you need to understand your time — nothing you didn't ask for.
Trends & comparison
Day / week / month activity trends, plus this-week-vs-last-week by category.
Focus score
Productive ÷ distracting, a daily streak, and a focus trend over time.
Activity heatmap
Which hours of which days you actually browse — at a glance.
Auto-categorized
Work, Dev, Social, Media and more — recognized automatically. Re-classify any site with one click.
Encrypted backups
Export your full history as JSON, optionally passphrase-encrypted (AES-256-GCM). Restore on any device.
