Do you think the opinions on this app are a good representation of the population or does volunteer bias play too strong a role.

Volunteer bias is definitely skewing things. You need a random sample, not a self-selecting one to get a true representation of the population.
Certain elements are heavily over-represented on this site.
Excellent question by the way - a lot of people don't get this at all.1

No its not a good representation of the population. Nor does it need to be, its not a research tool. That doesn't mean you won't occasionally come across people with helpful ideas or thoughts.0
