SINGAPORE - A new "one-stop" mobile app that will allow people to provide feedback on a wide range of municipal issues - from pests to dirty footpaths - is being tested with the aim of a rollout early next year.

With the app, residents will no longer need to figure out which government agency to complain to about problems in public spaces, said Minister in the Prime Minister's Office Grace Fu on Friday.

They can simply give their feedback using the app, which will have feedback categories organised by topic, such as pests or greenery, she added.

"You will not need to know which agency is responsible for which function... The system will route the feedback to the right agency," she said.

Ms Fu heads the newly established Municipal Services Office (MSO), which is launching the app as part of its goal to streamline city services so as to better serve residents.

The app is currently being tested by public officers, grassroots leaders and volunteers, Ms Fu said in a post on Facebook.

Another 200 grassroots leaders and volunteers from across the island will be invited to test the app, in order to try its "geo-tagging" functionality.

Geo-tagging is the process of adding geographical information to a database, and allows "for a more accurate description of the location" about which a user is providing feedback, said Ms Fu.

She added that the MSO will include additional features to the app in later updates, based on the needs of users.

The eight agencies currently under the MSO are the Agri-Food and Veterinary Authority, national water agency PUB, the National Parks Board, the Housing Board, the Land Transport Authority (LTA), the Singapore Police Force, the People's Association, and the National Environment Agency.

There are plans to include other agencies and types of services under the MSO later, added Ms Fu.
