Hi Hudson,
Women on dating apps receive a ton of attention. It is easier to get numbers from girls at social venues because the attention they are attracting is limited to the venue. That reduces the amount of competition you have to deal with.
Dating apps are a different story.
Unless you have a really good dating profile, you could totally get lost in the sea of dating profiles that are shown as potential matches to these women on a daily basis.
If you want to get more matches, you need to have much better photos and an alluring bio. This is how you set yourself apart from the myriads of men who are hoping that their dating profiles capture the attention of these women.
