I want to show you my mod here, which can only be used with an iPad at the moment. A windows client would also be possible if you are interested.
The mod is called "ts-joho-mod" (one day I might explain how the name came about). It is working with ETS2 as well with ATS. The iPad displays 3 gauges:
- an ingame-time clock
- a gauge for the remaining delivery time
- a gauge for the time until the next rest period
All expenses incurred during the hauling job (such as tickets, fines, etc.) will be summarized. At the end you can see the netto profit or loss of the job. Unfortunately the telemetry API (which will be used by this mod) doesn't provide a "refuel event". So you have to create it manually by yourself. Pictures are worth a thousand words.
Btw, the fines shown here are for demonstrating the possibilities only. Never ever I would do such things

Oh dear, you have cancelled the job.
As stated above you have to create the refueling datas by yourself.
The job is done.
The 5 switches and the slider at the bottom edge are for:
- setting the time format (12/24 hours)
- adjust the clock
- setting the weight unit
- setting the distance unit
- setting the volume unit (refueling)
- setting the brightness of the display
What is this "adjust clock" switch good for? The telemetry API provides the ingame-time as its own base time but without time zone informations. That is, accordingly to the time zone you are currently in, the "real" clock time can be 1 hour sooner or later.
Tapping slightly right of the switch turns the switch to the right and tapping slightly left - totally surprising - to the left. Tap and hold down the finger to move the brightness slider - on left side to left and on right side to, uhm, ... dont't know. Your settings will be automatically saved.
To create a refuel entry tap the fuel dispenser icon (see pic #3). As you can see there is no 'dot' button. Insert e.g. 34.0 gals. as 3 4 0, turn the switch to 'price' and insert the price of $3.68 as 3 6 8. Finally tap "Enter". Tap "CE" to correct your input.
To install the mod download this setup file:
https://www.sovoma.de/downloads/TSJohoModSetup.zip
unpack it to an arbitrary folder and double-click "TSJohoModSetup":
Now you have to operate this incredibly complicated setup program

Next, you have to install the iPad app. Go to the AppStore, enter in the search box "ts-joho-mod" (WITHOUT the quotation marks!) and install it. To use the app, simply start it. The app and the simulator will be found all by themselves, once the simulator is started and the mod is activated. There may be a little delay of up to 5 seconds. The condition, of course, is that the simulator and the iPad are on the same local network.
That's all, so far, I believe. Please let me know what you are thinking about this project and whether I should make a windows version too (e.g. for the Microsoft Surface).

P.S.: just in case SCS is reading this: the ETS2 still pretends to be "Euro Truck Simulator 1.16" via the Telemetry API v1.1

Wow, I can't believe it, it's so crowded here. Wow. Anyway, setup and app are available in german now; a russian version follows next days.
