The new app will deliver a rich multimedia experience with original reporting, podcasts, text-to-audio playlists, interactive puzzles and replica e-editions.
As part of the changes, Riverine Herald will consolidate its printed formats into two a week.
The new Tuesday and Friday editions will launch the week commencing Monday, July 14.
These changes will also apply to the Shepparton News.
Weekly MMG print publication dates for other mastheads will remain the same.
The printed format of the Country News paper will stay the same, but will move from a Wednesday to Tuesday edition for Riverine Herald readers starting the week commencing July 14.
“More than 80 per cent of our digital readers already consume our local journalism via their mobile phones,” Ross McPherson, chairman of the family-owned MMG, said.
“From late this month, we’ll be giving them the best possible mobile experience.
“We want our readers to have rapid access to the news and alerts they want, when and where they want it.”
Details of the new products will be released closer to each launch.
The company is also introducing bundled advertising packages across all formats — including Love the GV.
These new solutions, called Gamechanger, are designed to simplify access for advertisers to their audience.
The company said its announcement would allow the final parts of planning for the launches to be put in place with their clients, suppliers and staff.
“Our digital assets already help us attract 200,000 users every month across our region in either mobile, web, social or print,” Mr McPherson said.
“This gives local businesses unmatched channels to reach their clients.
“Importantly, this also helps keep their marketing spending within the local economy, instead of going to the big tech giants overseas.
“This is one way we help our communities thrive through our unique, local journalism.”
