Mobile navigator

Whatever you may say, only satellite GPS-navigation1 is an indispensable thing for travelers, tourists, car owners and other fans of orienteering. But so far, for cell phones (with outlandish exceptions), the built-in GPS receiver is nothing more than exotic. Meanwhile, there is another mobile solution that allows you to save information about the route, keep its timing and also remember the reverse route. Solution, to the point, software. Probably, many, after reading the last prescription, they snickered also prepared to repeat the words of the legendary cat Matroskin: "I suppose, the capital is impressive ...". You aimlessly so, the program is free. In general, enough to feed our readers with intrigues, it's time to move on to the heroine of today's note.

TripMate - this is the name of this pocket navigator. With the creator of the application - Konstantin Knizhnik - regular readers of "Computerra Online" should already be familiar from our past publications in the mobile category. The Java midlet developed by him occupies 19 kb in the phone's memory and is also operable on any device supporting Java technology (MIDP 1.0).

How does a cell navigator work? Simple enough. At the source of the route, select the New command, then in the process of moving around the area we mark each stage of the excursion and also enter the necessary information (direction of travel plus, if desired, a comment). It is allowed not to think about fleeting characteristics of the route, since the program automatically calculates the spent pores at each stage. On a halt or at the end of the tour click Finish.

Now, at what time the passed route is stored in TripMate's memory, it is allowed to go through one more time in a direct (Navigate) or reverse course (Navigate Back). In this case, the phone’s display in graphical mode will display the move pattern (a moving triangle), only in text mode — a detailed description of the route, indicating the pores in the route, also the comments previously entered. We hope the animations below clearly demonstrate the labor principle of the application.

If you are moving along a route ahead of schedule, then the Next button is useful for moving on to the next stage, only in case of a backlog, the Suspend / Resume keys allow you to slow down / activate program execution.

The current version of TripMate allows you to manipulate, unfortunately, so far only one route, but without limitation on the number of feasible stages (read, the duration of the journey). In this case, each of them is allowed to subsequently edit or add a series of new stages.

Let's sum up. The program is no doubt an interesting one. Take, for example, the possibility of maintaining automatic timekeeping, memorization of the direction of travel, as well as a graphical display of the route plan. So, if you are lost in the labyrinths of fate, the chosen tool for finding a way out cannot be found.
