Tariff selection for mobile. Evolution-Revolution

  The project MyTarif.ru (nee SmartTarif.ru ) is one year old. Throughout the year, the service expanded, improved and evolved :)
  The main idea of ​​the service is to help in selecting the most favorable mobile communication tariff, taking into account all the features of the user's communication style. At the same time, all possible saving options and tariff parameters are used to the maximum.
Today we present to you, without undue modesty, a revolutionary :) step in the development of the service.

  At first, the selection of the tariff was based on an analysis of the detail of conversations. It was reliable and relatively simple for us as developers. But it turned out to be inconvenient for users: detailing is almost always paid, it must be ordered in confusing personal accounts, in general, there is still gimor.

  Then a simple and understandable “tariff calculator” was born - the site visitor independently sets how many minutes he says, how many SMS messages he sends, how much Internet he downloads.
It’s convenient for the user, fast, but not reliable: not everyone can say for sure how many SMS a month he sends, and how often he calls mobile on weekends or city nights. In addition, a valuable opportunity is lost to suggest which number is more profitable to make a "favorite."

  Now we present to you a new stage in the development of the service - mobile My Tariff. There is no need to pay for call detailing if all the necessary information is in your mobile phone! Many smartphones have access to call logs, SMS archives, and information on GPRS traffic. Or not in many, but at least in androids. As the owners of Google phones, the developers realized their fantasies on this platform.
  The calculations themselves and the selection are carried out on the server. The “My Tariff” program works as a drill generator, which is then analyzed on the server and the analysis results are displayed immediately on the mobile.

   At startup, the program displays information about the minutes spent talking, SMS, the amount of spent mobile traffic. Logs of SMS and calls are easily accessible to the program, but with the calculation of traffic, by the way, it was not so simple: the android stores just the amount of traffic after the last reboot of the phone. Those. excluding the start time of sessions, without specifying the size of individual sessions. And because of all sorts of tricks with the “rounding” of volumes, the calculations can be nontrivial. I had to make my own mini-daemon, which would save the log of using GPRS.

  Directly from the screen for a detailed description of the selection results, you can go to the selected tariff, or connect the proposed option. For example, by clicking on the button “switch to this tariff” a dialer with a filled-in number will be opened to switch to the tariff. The user only has to confirm the dialing of this number by clicking “call”.

   Thus, the procedure for selecting a favorable tariff is simplified as much as possible and becomes convenient and affordable. Hurrah! :)
   Regarding the relevance of tariffs - Moscow and St. Petersburg - almost 100% correspond to reality. We bring to mind Omsk, Novosibirsk. Tariffs in other regions will still have to work. We select the tariffs of the Big Three and Tele2. Tele2 tariffs are selected for all regions.
