Track every shift. Mind your limits.

Chronos is a shift tracker with a conscience. Log a shift in seconds, see your hours by day, week or roster, and get a gentle nudge — never an alarm — before the hours quietly add up to too much.

A shift in seconds

Your usual start, length and break are pre-filled. Most shifts are two taps and done.

🗓️

Built for rosters

Rotating roster cycles are first-class — totals follow your real pattern, not just the calendar.

🌿

Watches your wellbeing

Day, week and roster limits you set yourself, with kind reminders when you drift past them.

The signature feature

An Effort Engine, not a stopwatch.

Most trackers just count. Chronos reads your hours against limits you choose and tells you, plainly and kindly, how you're tracking — so a heavy stretch never sneaks up on you.

Five honest readings

The same calm scale runs across your day, your week and your whole roster.

How it works

Logging that stays out of your way.

The Add shift screen with date, start and finish times, break and shift type pre-filled
Fast logging

Most shifts are two taps and done.

Chronos pre-fills your usual start, length and break from settings, so adding a shift is mostly confirming what already happened. Worked something different? Nudge the times and save.

  • Sensible defaults on every new shift
  • Mark it Normal, TOIL or Leave
  • Breaks come straight off your worked hours

Honest hours

Normal, TOIL and leave — counted correctly.

Time off in lieu subtracts, leave sits at zero, worked time adds up. Your totals reflect what you were actually owed and actually worked.

Limits you set. Nudges, never alarms.

  • Set your roster length and start date once
  • Defaults that pre-fill every new shift
