Angkas ingeniously makes use of motorbikes to get its passengers through Manila's notorious traffic gridlocks, giving it an edge over its car-based ride-sharing app rivals.
While the post was later deleted, it did not escape the attention of the police, who posted a screenshot of it on Twitter with a call for regulators of the transportation industry to take action.
"This is not acceptable to commuters. Angkas will scare people off with this. This is not promoting public safety in transport business anymore," the Philippine National Police said.
However, other social media users also hit out at the police for its alleged double standard.
Some posted links to news reports about Philippine President Rodrigo Duterte cracking jokes in public about rape, which critics allege trivialise sexual violence.
"Can we call your attention to this person too? This person is not promoting public safety and decency anymore," Twitter user Petey Pablo posted.
"Call out your president first before other people," said another Twitter user called Drew Arellano.
Duterte's aides have previously defended the President's crude comments, saying they were only intended to make people laugh.
