Their challenges

Even the biggest giants, they always have their challenges. When Vietnammm converted their business from website to Mobile Application, they met a lot of difficulties. At first, their App was drowned in the Oceans of Applications which were known as App Stores (both Apple App Store and Google Play). Moreover, increasing the number of Installations becomes the second challenge. Without the number of installations, BAEMIN Vietnam will be a dead-app obviously. Finally, Vietnammm had to keep in touch with their new users and walk along with the loyal-users as well.

Our approaches

At first, helped Vietnammm with the full package Media Plan for User Acquisition to get more Installations and New Register User. Second, we advised them on changing the Target Audiences, focusing on the big cities like HCM City and Hanoi. Finally, kicked off a short Campaign within 15 days and then we compared the results with Vietnammm’s expectation.


The result of the testing Campaign:

  • The number of Installations overtook 120% of the expectation.
  • The RR7 (Retention Rate day 7th) increased by 22%.
  • The Customer Acquisition Cost decreased by 35%.

After this testing phase, AppROI became the Integrated partner and we cooperated with each other in 3 months later

  • The number of NRU increased by 17% more each month.
