This app provides a criterion for deleting one of the songs (albums) registered from a physical CD and the songs (albums) acquired from the network by subscribing contract, if one is double-registered. It will be a tool for this purpose. When this app is started, if the same song is registered in duplicate, it will be displayed as a list. As detailed data, information such as the date and time when the song was added, the last performance date and time, the number of performances, whether it is a cloud item, etc. is provided. Based on this information, select which songs to delete and which songs to keep. When you decide the song to delete, tap the cell in the detail part. Tap to automatically go to the standard music app on your device. In the standard music app, the songs that you plan to delete are already selected. If you delete it with the standard music app, the double state will disappear. Note: Due to the technical specifications, it is not possible to delete songs registered in the music library directly from this app. Finally, if one minute has passed since the application was started and nothing is displayed in the list, it means that the song that is double registered cannot be detected.

The Light Control app improves efficiency, flexibility and convenience when working on site. It allows 4K5 work lights to be controlled from a smart phone over a wireless connection. The output of the light can be dimmed in five levels from 20 % to 100 % for optimum and quick adjustment to the actual situation and task. In addition to the display in per cent, the set light level is easy to identify from an easy-to-read graphic. Four work lights can be connected to the app at the same time. It is also possible to operate a work light from two smart phones with synchronised operating status. For work lights running from a battery, information on the charge is provided by a colour and per cent display. The power consumption can be effectively reduced by adjusting the light output to suit requirements as only as much electricity is consumed as is required to complete the task. The work lights can be quickly switched off remotely when leaving the site.
