I was in Manila two months ago. Didn't get anything on Hornet, but plenty of action on Grindr. Thought of using Romeo as I've heard fro some of my Filipino friends that they use it, but I got lazy.
Blued has a lot of functionalities but it's a pretty heavy app and can get a bit clunky especially if you use the free version.
Nonetheless, both Hornet and Blued are much popular in Vietnam and Thailand than they are in the PH, so I would give them a try if I were you.
