Dating apps are great. I've recently met somebody through a dating app and we're getting along very well. Way back when, I met my wife on a dating app and whilst that eventually went south faster than a migrating swallow fucking off for the winter, that wasn't really the fault of the app.
Try not to pay attention to those who try to dissuade you from using them in favour of "just go out and meet somebody". I mean sure, this worked like a charm 20-30 years ago before everyone became insular and suspicious of anyone who might try to initiate a conversation. And not everyone's in a position to rely on socialising with friends and meeting somebody organically through work, or socialising or via their hobbies. There is an obvious need for dating apps as they're used by hundreds of millions of people globally.
Quick review of some popular options:
Tinder
Tinder is okay. It's otherwise the simplest form of a dating app - swipe left, swipe right. Short "about me" section. It's easy to use but has a much younger average userbase. There are a lot of users who turn to it because it's the most widely used app, but whilst it has the highest number of users and a lot of them are "looking for a relationship", the experience of using the app itself is rather superficial, and the interactions you have on there lean towards the same.
Bumble
I like Bumble specifically because the emphasis is on women sending the first message. It means that you can like whomever you want but that their inboxes are less likely to be spammed to buggery by every Tom, Dave or Harry who just says "Hey, wot u up2?". It means that you're more likely to establish meaningful dialogue when there is a match and they do reach out. Bumble has changed to allow for women to set a 'conversation starter' which allows men to make the first contact, but I think that's a cop-out and never bother. It defeats the purpose of using Bumble in my opinion.
I also like the variety of profile options, with the 'about me' section and several conversation prompts.
It doesn't make much sense to take the "swipe right as many times as possible" approach on Bumble as once a match is established, they have 24 hours to reach out to you and then you only have 24 hours to respond to their first message. The countdown is removed after both parties have sent their first messages but if you're trying to power-user your way through as many matches as you can this can lead to an unmanageable amount of conversations to try to juggle at once.
Hinge
This one was new to me - I'd heard of Bumble before and used Tinder previously but Hinge seems a lot more recent. It works on mostly the same premise - you swipe on profiles you're interested in. Once matched, anyone can send the first message. There's no "about me" bio section, but you can use various prompts or other boxes to talk a little about yourself. I like that it has an option to share a 30-second video of yourself, and also a 30-second voice recording (both come with topic prompts for context). I don't like that you can't send pictures through the app but to be fair that's probably because 99% of images guys send in DMs are unsolicited phallic grotesqueries. You can still send voice notes though which I prefer to typing, but that's not everyone's cup of tea.
Other
I'd say that out of the biggest three, Hinge was my favourite user experience. Other websites such as Match.com and eHarmony are pretty good for finding relationships and depending on a person's age there might be an argument for SilverSingles or Ourtime but I don't have any experience with those.
General Advice (for anyone using dating apps)
Don't just swipe right on everyone. Read somebody's profile before messaging. Don't just say "Hey, how's it going?" as it's boring and unlikely to get much interaction back. Keep your lower age criteria to half your age, plus seven - there are a lot of young women on these apps and they don't want to be made to feel uncomfortable by interest from crusty old fuckers who are old enough to be their dad - or their granddad. Take rejection on the chin - you aren't supposed to be liked by everyone, so don't take it personally if somebody doesn't feel like you're their ideal choice. Always be respectful. Don't send any dick pics. Treat dating as an adventure - don't pin your hopes of happiness on your success within the app. Be honest about your intentions - don't waste anyone's time if you're looking to put a ring on it and they're just after a short fling. And, most importantly, just enjoy it and don't take it too seriously.
Anyway, just some general thoughts. Nothing aimed at anyone in particular. Good luck on your dating journey!
