Application My Car for Android

As I promised at the end of the other post, I published the result of my bachelor's thesis to The Android Market. It is costs of running a car administration application called My Car. The application allows you to quickly and easily manage the traffic of your cars.

(the following description applies to the first version of the application 1.0, so don't miss the list of recent changes below)

You can create multiple user profiles. Each user can manage the traffic of his cars, which consists especially of records of refueling, service inspections or notes. You can assign the driving profile to each refueling. Driving profiles define the way and style of driving since previous refueling (e.g. type of tyres, amount of load, driving style, air conditioning usage, ...).

traffic of selected car.

Tab for managing and
selection of the cars.

Adding a car.
You can filter the traffic of your car, so that the only informations you want will be shown. You can use several criteria - type of record (refueling, service, note), consumption (low, average, high), driving profile or state of odometer. Traffic stats are always calculated according to current filter. For example, you can easily find out average consumption of your car when winter tyres ase in use. Major informations in statictics of car's traffic are average consumption, financial costs and carbon dioxide (CO2) emissions.

Application QBright for Android

I published one of my first applications for Android to The Android Market. It is called QBright. The application allows quick and easy adjustment of display brightness. You can launch it from anywhere just by long pressing the 'search' button. It contains four editable buttons for quick adjustment.

The main purpose of its publication to The Android Market is testing how this process goes. Although the application itself is very simple I found it very helpfull. I've been using it for almost a year.

  • Now, you can disable automatic brightness control faster than ever. Because manual brightness change causes automatic brightness control to turn off (thanks Melvyn for suggestion).
  • New application icon.
  • New yellow theme was added.

Version 1.4 (15.8.2011):
  • New switch was added. It enables you to turn on/off the automatic brightness control.
  • Now you can support the development of application. If you want to appreciate my work, you can send me a donation to encourage the further development of the application. Or you can use 'Donate' button on this website.

Version 1.3:
  • For each quick adjustment button there is an option to hide it

Version 1.2:
  • Option to automatically close the application when brightness is selected

Version 1.1:
  • Brightness adjustment now uses percentages
  • Application includes ActionBar with 'close' button

Application QBright.


Launch it from anywhere
just by long pressing
the 'search' button.

automatic brightness control.

Ability to hide button(s).
    I am also planning to publish my bachelor's thesis to The Android Market. It is costs of running a car administration Android application called My Car. The manual is available on the internet, but only in Czech language for now (updated - English translation has been added).
