Transnational Komatsu Corporation is the second largest manufacturer of construction and mining equipment in the world after Caterpillar.

It is headquartered in Tokyo, and has subsidiaries in many countries, including Russia.

The customer decided to upgrade the application to provide engineers with a more modern, responsive and convenient tool for collecting data on machinery operations and calculating productivity.

The application should have a simple and clear interface so that employees can quickly generate reports on the performance of excavators, dump trucks, loaders, bulldozers and other equipment.

We undertook the entire cycle of creating the application: we drew a prototype, thought over the design and wrote the code.

The customer asked us to develop an app based on the same code base for both mobile platforms - iOS and Android - using the Flutter framework.

Since the tool will be used by engineers from different countries, the application should support Russian and English languages. The flutter_localizations library helped us localize the application.

The data about the measurement results, which are stored on the device, had to be presented in a convenient and familiar form. We chose a table in Excel, which is a universal format familiar to everyone.

We have divided all the operations that the user performs in the application into four categories: "Working Conditions", "Metering", "Report" and "Settings".

All tabs are permanently displayed on screen in the top menu, so it's easy to switch between them in any user scenario.

Regardless of the selected working conditions, all measurements take place on one screen.

Engineers measure for the same special equipment, so many parameters are repeated.

To avoid having to enter the same data every time, we connected templates. With these templates the data is filled in automatically.

On the "Reports" screen, the engineer sees all the reports he has generated. Each report can be sent or deleted - there are special buttons for this.

For new technicians we have the "Help" section. It contains recommendations on working with different types of special equipment: dump trucks, excavators, bulldozers and others.

Each user can enter the "Settings" section to customize the application. For example, you can enable vibration feedback on keystrokes or rename operations.

With the new application, engineers generate reports faster and avoid typical errors. As a result, the customer's company does more work per unit of time - and doesn't lose money.

Komatsu has a separate team of engineers who are responsible for optimizing the customer's machines. We developed an application specifically for this team.

The job of these engineers is to go out in the field, to the customer's site, to assess the actual operating conditions and to measure the efficiency of the machine. The app helps them do this accurately and quickly and prepare a report.

We tested the application at several enterprises in Siberia, and users highly appreciated the convenience of the application and the quality of the report files. These reports help to make recommendations to the customer on efficient use.
