Bulli Level for PC

The app is used to level the vehicle (camper, caravan....). It uses the cell phone's internal sensors to determine its position.

Why another app like this, aren't there already enough? (please read the long text)
I think there are some good apps on the market, but as far as I know none of them have the option of connecting another device via Bluetooth, for example.
The transmitting device can be located on the back of the bed, on the table or another suitable surface, for example, while the receiving device is positioned in front of the driver (this is independent of the position, so it can also be safely in a holder). Or the transmitting one can be placed in the caravan while the alignment is being carried out outside.

Furthermore, the alignment can be changed (swap up/down, for example). For example, the (transmitting) device can be positioned on the display. This is helpful if the back is not sufficiently flat, or as protection for the display.

The tilt angle and the height difference to be compensated for so that the vehicle is level are displayed. The track width and wheelbase are also entered in the setup. The app also works without this information, but then, logically, the calculated compensation is not correct.

It is also possible to output the correction values by voice.
The beeper function is under development (still needs to be tested and perhaps optimized). The correction values are output as a beep, similar to the distance warning device. The lower the required compensation, the shorter the pause between the beeps.

The help (instructions) and the settings can be accessed via the "hamburger" symbol (the 3 bars at the top left).

2 small notes at the end.
I programmed the app in my spare time. If something does not work or if there are any wishes, please let me know and I will see what I can do.
My English is unfortunately not the best, but fortunately there is support through translation programs :-)
