I would not go into radial menu unless it is some kind of specialist app. I would cut it down to left/right up/down - yes tinder is quite binary and does not have "maybe" as an option.
Still you have to build database of choices which will cost quite some money.
Tinder has this upside that their database of choices is building on its own.
