Chronos Time Tracker

Features
Read full description

Chronos helps shift workers stay on top of their hours — without stress. Log each shift in seconds. Chronos pre-fills sensible defaults based on your usual routine, so adding a day's work is a quick tap, not a form. Adjust times, add a break, pick your shift type, and you're done. TRACK WHAT MATTERS • Daily, weekly, and roster-period summaries at a glance • Gentle effort indicators show how you're tracking against your limits — calm green to soft coral, never alarming red • Supports Normal shifts, TOIL (Time Off in Lieu), and Leave — TOIL hours automatically offset your worked totals ROSTER-AWARE Set your roster cycle length and Chronos keeps a running total across the whole pattern — useful when your working week spans a rotating schedule. EXPORT WITH ONE TAP Share a CSV of your full shift history for payroll, tax records, or your manager. Everything is generated on-device and shared on your terms. PRIVATE BY DESIGN Your shifts never leave your device. No account. No cloud sync. No tracking. Just your hours, yours. Chronos is designed for nurses, paramedics, factory workers, hospitality staff, and anyone whose week doesn't follow a nine-to-five.
