The app Tachograph will help you very easily monitor the mode of work and rest of the international driver.

The Tachograph app has detailed tips on all modes of operation and timers.

When following instructions and prompts, the Tachograph app will not allow violation of work and rest schedules.

The app has a convenient journal where all your shifts are automatically recorded, so you no longer need a notebook for shift records.

Just switch the modes of the app in accordance with what you are doing (Driving/Rest/Work/POA), and the app itself will start the necessary timers and show you all the necessary information.

To switch between work and rest modes, the app has buttons with corresponding names:
- Driving
- Rest
- Work
- POA

Hints on modes of operation can be called by pressing the symbol (?) when selecting any of the modes of operation.

There are 9 timers in the main window of the program:

- Daily rest period 9/11
- Weekly driving 56
- Weekly rest period 24/45
- Two-week driving 90
- Weekly time 144
All timers start automatically, depending on the selected mode of operation.
By clicking on the name of the timer and the symbol (?) you can call a hint for any of the timers.
 
By going to Menu - Journal you can view and edit the records of all your saved shifts.
Description of the journal is: Menu - Journal - Journal menu.
A hint for the shift editor is: Menu - Journal - Shift - Shift Menu.
