We had created iOS and Android applications design within MTS corporate guidelines.
An employee monitors all assigned tasks and objects on the map. Each task can be filtered by status.
Entering an object zone, an employee is offered to “check-in”. That is necessary to track time employees had spent on the object.
The tasks are easy to work with: they can be sorted by status or distance from employee's location, activating the list mode.
Some of the tasks might need precision, which can be made in the “centre” communication messenger.
