There are several ways of switching to the 'Tracking' mode. One of them (switching from the 'Map' mode) has been described in the previous section. The other way is to move from the work list ('Units' mode). To do so, tap the line of the necessary unit in the work list.

'Tracking' mode provides you with a possibility to monitor both unit's location on the map, and parameters received from a unit. Note that unit's location can be shown as address (by default) or as unit's presence in geofences ('Geofences as addresses' flag in 'Other' section of Wialon Mobile Client's settings)


You can view unit's events on the 'History' tab. All the events are presented here chronologically.

Types of events and provided information:

Event's start time, duration, covered distance, unit's average speed

Event's start time, duration, location address

Fuel filling
Event's time, amount of fuel filled, location address

Fuel theft
Event's time, amount of theft, location address

Choose any event in the history to display it on the map. In order the map to be centered on a unit of monitoring, tap its icon.

:!: Note that some values of event parameters (time intervals, amounts of fuel, unit's location) may differ from the values of the same parameters in the reports of the monitoring system. It occurs due to the implementation of different calculation systems in main Wialon and in Wialon Mobile Client. For example, upon detecting fuel fillings/thefts, mobile client uses time of a last message received before a fuel level changing, while main Wialon uses time of the first message from the interval with the biggest difference of fuel levels. Moreover, movement state in Wialon Mobile Client is determined only by GPS speed, while other methods can be used in main Wialon.

:!: Note that in Wialon Mobile Client the correctness of data received on any event depends on parameters indicated on the trip detector tab.


The 'Info' tab displays an extended unit's information: location address, attached drivers (with phone numbers) and trailers, equipment data, values of custom fields, sensors, counters, and parameters.


On the 'Timeline' tab you can visually identify events' duration, find out their number, and get full details on events (tap events bar). You can work with the following event types: trips, fuel fillings, fuel thefts. Moreover, both sensor state changing (ignition sensor, custom digital sensor) and sensor values increasing (mileage sensor, relative odometer, counter) are considered to be event types as well.

You can view up to 4 event types on the timeline. Trips, fillings, and thefts are chosen by default (names are displayed in the bottom of the screen). To choose other types, summon the corresponding menu by tapping any event type in the bottom of the screen.

Working with Events

Stripes of different colors shown on the timeline are called event bars. The size of an event bar depends on duration and number of events in it. There can be either single or multiple events in a bar. A multiple events' bar always shows a number of events it contains. To view an extended info on events, tap a corresponding bar. The extended info features a list of events and their details. Here you can choose events to be shown on the map.

Chosen events are both shown on the map and placed in the event basket above it (). The basket indicates number of chosen events. To view details of events in the basket, tap 'Basket' icon. To center and scale the map on any event in the basket, tap this event.


The application supports a locator functionality. Locator is used to generate links and share current units' location. Locator can be available either from the work list ('Units' mode) or from the 'Tracking' mode. To generate a link, use left swipe in the line of a corresponding unit, and tap the 'Target'. In the appeared menu, choose locator's link validity period (from 1 hour to week). Then choose a necessary action: send a location link by any messenger on your smartphone, copy it, open in a browser, etc. Viewing is performed on locator's map which becomes available upon clicking on the provided link.
