Auto acceleration. How the dynamics of acceleration of a car is determined, and how acceleration affects fuel consumption How is the dynamics of a car determined and how it is related to fuel consumption

If you have always considered themed applications for smartphones to be some funny toys that can only sometimes be useful in certain situations, then it's time to look at the situation in a new way. Applications are able not only to perform some specific functions or provide information support, but also to bury entire segments of various devices alive. For example, it was they who practically destroyed the car navigator market in a few years. And the target has long been another victim. But we will not make predictions and will simply share those applications, or, more precisely, their varieties, which we ourselves seem to be relevant and interesting.

Measurement of acceleration

  • Version: 2.1
  • Google.Play rating: 3.7
  • Number of installations: 50-100 thousand
  • Size: 4.9 MB
  • Link to the program:


What Russian doesn't like driving fast? And fast acceleration? A smartphone is a perfectly suitable tool for measuring these parameters. The majority of such programs base their indicators on data not from a GPS receiver, but from an acceleration sensor. The GPS-receiver has extremely low accuracy for these tasks and a gigantic error. However, there are programs whose developers claim that GPS is also used to obtain readings and correct results.

Acceleration measurement uses only data from the acceleration sensor. Calibration must be performed before starting. Fixing the result will start automatically with the start of the movement. The main thing is not to hold your smartphone in your hands. This is the most common mistake among those who give this and all similar programs a low rating. The smartphone must be firmly fixed in the cradle! At the end of the measurements, the program saves the result and can show the final graph.

If you have a car with mechanics, then keep in mind that if it took you more than 0.5 seconds to change the next gear, then this is a rather weak result. Pros switch at lightning speed - literally with blows (if you practice, don't kill the box).

In addition to measuring the dynamics of acceleration in the application, you can specify a number of technical characteristics of the car, and then it can also plot power and torque graphs. Overall, the app is good, but tends to overestimate the results. Although it all depends on the quality of the built-in sensor in a particular smartphone.

Video recorder RoadAR

  • Version: 1.4.8
  • Google.Play rating: 4.3
  • Size: 26 MB
  • Link to the program:

The DVR is the same smartphone feature that could undermine the real market segment, but so far this has not happened. I don't think it will happen in the future either. However, those who need this function from time to time can easily get by with software solutions, of which there are quite a few, and many of them have an extended set of additional functions, such as RoadAR.

The application does an excellent job with its primary responsibilities. Time, coordinates and speed can be superimposed on the video. But there is no separate saving of short video clips on events from sensors. But there is a function of recognizing road signs: speed limits, pedestrian crossings, "give way", prohibition of overtaking, prohibition of stopping and parking. If necessary, the application displays warnings, for example, if you stop in the area of \u200b\u200b\\ u200b \\ u200bthe stop and parking prohibited sign or accelerate strongly in front of a pedestrian crossing.

In general, the character recognition works quite well. But you need to understand that the phone camera is not designed to work in backlight, therefore, on sunny days, all the functions associated with the camera will not work satisfactorily.

And one more caveat: RoadAR is very demanding on hardware resources. During the trip, when recording video, it drives two 1.2 GHz Cortex A9 cores to 100%. If you have a weaker single-core smartphone, then it is better to use another application, for example or.

Auto Expenses

  • Version: 1.91
  • Google.Play rating: 4.5
  • Number of installations: 5-10 thousand
  • Size: 5.4 MB
  • Link to the program:


There is a category of citizens who like to scrupulously calculate expenses. There are those who are just wondering what it actually costs one kilometer of mileage on their car or one month of its maintenance. And there are serious revelations here. Many people are surprised to learn that if they walked for three years, they would have paid their mortgage long ago. And a beer with friends after work would be a nice bonus.

There are also those for whom it is important not to miss the next replacement of candles or an air filter. In all these cases, apps like Auto Spending will come in handy. In the aforementioned application, you can separately keep track of a large number of expense categories, keep track of when and which consumables have changed, plus set up reminders for their periodic replacement, which is very convenient.

Car lawyer

  • Version: 3.5
  • Google.Play rating: 4.4
  • Number of installations: 0.5-1 million
  • Size: 2.1 MB
  • Link to the program:


The application contains step-by-step instructions and scenarios for communicating with traffic police inspectors in case of traffic violations or disputable situations. It also contains comments on the drafting of protocols, various reference and related information, including the amount of fines and other educational measures. Plus a user-friendly interface.

The free version of the application has not been updated since spring 2013, so some of the information in it may be outdated. However, in general, it is quite suitable for everyday practice. And if you want to have more relevant information at hand, you can additionally install the application "".

Traffic fines

  • Version: 1.0.6
  • Google.Play rating: 4.3
  • Volume: 12 MB
  • Link to the program:


There are applications that help you check whether fair (or not so) retribution has overtaken you and whether there are any debts to your homeland in the form of unpaid fines. TCS Bank's version called "Traffic Police Fines" is a little more practical than some of its competitors. Its advantages are in the presence of a notification system (subscription), which will notify you of the appearance of "sudden debts" for you. The application "" is no less popular. It is supported by a large number of devices and has the ability to pay not only with a bank card, but also with Yandex.Money.

AALinQ Player in Car

  • Version: 1.2.1.0
  • Google.Play rating: 3.4
  • Number of installations: 100-500 thousand
  • Volume: 3.2 MB
  • Link to the program:


Initially, this player was created as a software part for working with external hardware units that expand the capabilities of built-in speaker systems of various cars. After all, automakers were able to teach their cars to play MP3 about 10 years after every second student had MP3 players in their pockets. Therefore, various companies have proposed and are offering their own solutions that make up for this omission.

AALinQ is quite suitable for those car owners who have not yet installed a USB drive instead of a CD changer in their "rare Lexus" or who have Aux connectors or the ability to connect via Bluetooth.

The player is quite standard in its functions. And sharpening for automotive use is expressed in large interface buttons and the ability to control playback from the lock screen. This is useful when the smartphone is not charged in the car, but is used as a sound source, and in this case, in accordance with the settings, the screen is dimmed to save battery power.

GPS AntiRadar Free

  • Version: 1.0.39
  • Google.Play rating: 4.3
  • Number of installations: 0.5-1 million
  • Size: 11 MB
  • Link to the program:

In the free version, this is an extremely simple application. The neat interface has only two buttons: one activates camera alerts, and the second allows you to add new detected cameras to the database. For each camera, a speed limit for this area and a monitoring direction are prescribed. In the settings, you can limit alerts only if the speed limit is exceeded by more than 19 km / h. The only minor flaw is that all cameras on the roads are considered radar cameras.

In total, at the moment, the database contains a little over 9 thousand cameras throughout Russia, and you can familiarize yourself with their location.

As an alternative to GPS AntiRadar Free, we can recommend the application, which is largely successful, has more than 500 thousand objects in the database, but warns about cameras on dedicated lanes for public transport, speed limits and speed bumps only when you subscribe. And the price bites.

Where is my car parked

  • Version: 1.51
  • Google.Play rating: 4.0
  • Number of installations: 1-5 thousand
  • Volume: 3.2 MB
  • Link to the program:

Blondes with topographic cretinism, mushroom pickers and travelers are for you. There are many similar applications, and this is what we took solely because of the Russian interface. The application has only two buttons: remember your current location and show the remembered location on the map along with your current one. Nothing more.

If you are not afraid of the English language, then it is better to install another more popular application - You can store several places in it, as well as add photos and notes to tags, for example, the number of a parking space and a floor in a multi-storey parking lot.

iOnRoad - road assistant

  • Version: 1.5.1
  • Google.Play rating: 3.8
  • Number of installations: 0.5-1 million
  • Volume: 5.2 MB
  • Link to the program:





You don’t have a Mercedes and the opportunity to order a tracking system for road markings, distance to the vehicle in front and navigation with augmented reality mode? No problem. One of the most powerful startups in history will fill these gaps.

Before starting work, the smartphone must be securely fixed in the cradle and its position must be aligned with the virtual levels that appear on the screen in case of a noticeable deviation along one of the axes. After starting to move, the application takes 5-10 seconds to analyze the picture and recognize the markings and other objects in the frame. While driving, the smartphone screen displays the distance to the vehicle in front, and warning signals sound in case of danger. The same thing happens when you cross a solid scaffold line. In general, the application works well, but the absence of a hood on the lenses of smartphones' cameras makes the built-in camera difficult to work on sunny days. The screen is lit up and object recognition deteriorates.

In addition to the main function, the application will display the text of the incoming SMS, transfer incoming calls to the external speaker and help you find the place where you parked your car. Moreover, it will bind an automatically taken photo from the camera to this location and offer to set a timer with a reminder. It will also save snapshots of unforeseen situations in moments of sudden maneuvers or braking. The application can run in the background and will not interfere with other navigation programs.

But the main thing is that there is a video recorder function. Alas, paid. However, with her, all these not always stably working "bells and whistles" make sense.

Transport of Moscow

  • Version: 1.4.2
  • Google.Play rating: 3.8
  • Installs: 0.1-0.5 million
  • Size: 26 MB
  • Link to the program:




The application contains a large amount of various reference information and several services. In fact, this is a repackaged and slightly augmented piece of the Moscow State Services application. The main item in the application is a map on which you can display up to 13 layers: intercepting parking lots, gas stations with high-quality and low-quality fuel, parkon routes, parking lots, payment machines, etc. In Services, you can check a taxi for legality, see the list of issued fines and search the database of evacuated cars. The "Help" contains traffic rules, a list of fines, routes of land urban transport and a number of other useful information.

One of the key functions of the application is to send messages to other motorists using a license plate, provided that the owner has registered in this application or in the "State Services of Moscow" and has linked data about his car, as well as enabled notifications via SMS or push method in the application settings. Why are these notification methods initially disabled and they are not offered to be enabled when binding a car? This is a question for the developers. After all, this crosses out the entire advertised idea. Each new user needs to guess that notifications need to be turned on manually through the settings menu. Otherwise, it will be possible to find out about the received messages only by launching the application and going to the "Messages" section. Also, not all messages reach registered destinations. Sometimes they get lost.

Among other complaints - stability of work. Cloud services often "hang" for hours, while the application produces some kind of incomprehensible script errors, and guess what exactly the problem is. But despite all the negative, the app can be quite useful.

BlaBlaCar - Find fellow travelers

  • Version: 4.1.23
  • Google.Play rating: 4.3
  • Installs: 1-5 million
  • Volume: 10 MB
  • Link to the program:


If you want to cut down on gasoline costs on long-distance trips or are just looking for a company on the road, then the widely advertised BlaBlaCar on social networks is quite a suitable solution. By registering as a driver (or it is possible without registration at all), you simply indicate the start and end point, the date and time of departure, the price for which you are ready to take a passenger on board, free space for luggage and leave a comment. Then wait for applications from "horseless".

If you register, you will be able to add your photo to your avatar, indicate the make of the car and your attitude to communication on the road, listening to music, smoking and transporting animals in the cabin. And also statistics starts to collect on you, which positively affects your reputation in the system and will help you find fellow travelers faster in the future.

Breathalyzer - PartyFriend

  • Version: 1.1.3
  • Google.Play rating: 3.8
  • Installs: 0.1-0.5 million
  • Volume: 1 MB
  • Link to the program:


In the past, on weekends in the late afternoon, traffic police officers were often on duty at departures from cottage villages near Moscow, who caught the "early birds" and, for the presence of insignificant "exhaust", initiated the process of withdrawing a driver's license. The business was profitable for them, and it is gratifying that now this practice is coming to naught. Nonetheless. It is best to use a portable breathalyzer to time your check-out correctly. Although Chinese "toys" give a large error, on the whole they are quite capable of "hinting" when a little early, but when it is definitely possible. Well, if you do not have such a "toy", then you can use an approximate mathematical calculation using the appropriate applications, of which there are a huge number. The optimal ones will be those who, in addition to your complexion, “understand” that you drank all the mentioned alcohol not in one gulp at a strictly specified time, but for several hours. After that, an approximate chart of blood alcohol content will be built depending on the elapsed time. And "Breathalyzer - PartyFriend" is ready to help you with all this. But if you are not afraid of the English language, then you can install the application "" developer Netigen Tools. It gives a less optimistic estimate and also has a built-in reaction speed test. So, just in case, for the self-confident.

by the way, there is a method for measuring the speed properties of automatic telephone exchanges in accordance with GOST. so, for reflection ...
