Tachograph Drivers Hours Timer

You tap each mode change yourself: nothing reads your tachograph or driver card.
Drivers' hours countdowns for EU 561/2006, AETR and GB domestic rules: break due, daily driving, rest deadlines, the 56-hour week and the 90-hour fortnight.
Split breaks count properly: 15 minutes then 30 minutes resets your 4.5-hour clock, and every break start time can be edited afterwards.
Working time too: RTD breaks after 6 and 9 hours, the 60-hour week and your 48-hour average, with a printable 28-day record.

Tap the mode you are in, the same four your tachograph uses: driving, other work, availability, break or rest. Every limit counts down on one screen, the next one to run out counts down in a notification, and an alert sounds before a break is due or a rest must start.

What it tracks
- 4.5 hours driving, then 45 minutes or a 15 plus 30 split
- 9-hour days, and which of your two 10-hour days are left
- Daily rest: 11 hours, reduced 9 or split 3 plus 9, with the latest start time
- Weekly rest: 45 hours or reduced 24, plus the compensation you owe and its deadline
- 56 hours in the week, 90 across two weeks
- Working time: 6-hour breaks, the 60-hour week and the 48-hour average over your reference period, with leave credited
- GB domestic goods limits: 10 hours driving and 11 hours on duty
- Van mode for 2.5 to 3.5 tonne vans on international hire or reward work

Can I make it home?
Enter the driving left to get home. Dutyclock lays out the soonest order of driving and breaks the rules allow, from your own log, or shows where it runs out.

Missed a tap? Move, split or delete any entry and the countdowns recalculate. Started mid-week or mid-shift? Enter what your tachograph shows and what you are doing now, in one sheet, and a break already under way counts from when it started.

Export a 28-day PDF with a strip and totals for each day, weekly and fortnightly sums and working time, plus CSV and a backup you can restore on a new phone.

Alerts sound with an alarm tone and vibration. They use exact alarms, which Dutyclock asks for on your first tap; without them Android may deliver an alert a few minutes off. Nothing needs a tap while you drive.

One-time purchase. No ads, no subscription, no account. Works fully offline.

No location, no GPS, no sign-in, no tracking, no battery-draining background service. Nothing leaves your phone.

Dutyclock is an advisory planner for your own use. It is not a tachograph, not an ELD and not a legal record, and it does not replace your tachograph or operator records. Check it only when parked. Not affiliated with DVSA, the European Commission or any government body.

English interface. Ferry and train crossings, multi-manning, GB domestic passenger rules, the coach 12-day derogation and US or Canadian rules are not calculated.

Recent changes:
Two fixes. When a break or rest is nearly done, Plan now checks whether finishing it first gets you home sooner than driving now, and if so its first row says so, for example Finish the break, 0:04. Week now shows the same week its totals count: Monday to Sunday in UTC, as on your tachograph. Outside UTC the days show only their part of that week, the week is also given on your own clock, and it never says no driving while the totals have some. Advisory, not a tachograph.
