I've been using Hinge for the past year and half with a good bit of success, I can regularly go on 1-3 dates per week and have managed to keep that consistency pretty much all year.
IMO success comes down to 3 key things: profile, conversation and managing expectations.
First your profile, take high quality photos and weave in a story about your life in there. Guys think that it's the shirtless 6 pack that will get dates and while that's true, what I found is you have to build an "attractive lifestyle" through your profile. All my photos are of me doing things, on boats, outside, etc and all my prompts are things like "We should go kayaking together" and stories about travel. It's not one thing on my profile, it's the entire thing that builds a persona of a person that likes going outside alot and traveling, women find that very attractive in my experience.
Second is the conversation. You have to get good at actually "closing" a girl on a first date. There's a ton of "science" that guys will spew but it comes down to practice. The first couple of girls you talk to you will probably fuck it up, keep going and you will get better. My strategy here is to talk "lifestyle", where are you traveling, what shows have you seen, and NEVER EVER EVER BRING UP SEX.
Finally it's managing expectations. Most of these girls "fall through" not at the matching/conversation stage, but after the first couple of dates. Most of the time it's not something either person did, rather us realizing that we are just not right for each other. At this stage it's very easy to get bitter, the key is to keep going and not get bitter, and understand that if you're going to be playing the "online dating game", you're going to get a shit load of rejections.
At this point I do not even consider the "1st date" to be a real "1st date", rather I consider it to be a magic "0 date" that only applies to online dating. Usually on a first day you've already had one interaction with that person to figure out that they are worth going out with; however, with online dating you don't have that. So I consider the first time we meet to be more of a screener date, don't expect to go home with the girl, don't even expect a kiss, just make sure you like them and think if you would like to see them again. For these dates I usually go to a coffee shop mid-day, if it goes well we can schedule a longer dinner/activity date, but if it goes off the rails you can cordially end the date in about 15 minutes.
