There is no single best app for every man in South Africa, but four are worth testing: Tinder, Bumble, Hinge and Badoo. For a relationship, start with Hinge or Bumble. For the biggest crowd or something more casual, add Tinder. Give two of them the same photos and the same opening lines for two weeks, and keep the one that gets women to answer and agree to a plan.

The four to know

Tinder has a very large user base, which tends to mean quick responses in the bigger cities. It is the app most men have heard of, and a dating coach says it has a hookup reputation.

Hinge is built around written prompts and is aimed at people who want something longer lasting. A connection starts when one person likes a photo or a prompt answer.

Bumble is a mobile app with a swipe-based Date side. When two people match, a conversation has to start within a time limit, so it rewards a man who writes back the same day.

Badoo has a free version that lets you match and chat without paying, which makes it an easy one to try next to the others.

These apps change their features often, so check what each one offers in its own screens before you rely on any detail.

Best for a relationship

Men who type this question usually want a girlfriend, not a string of dates, so choose by what the app says about itself.

Hinge says it is designed to be deleted, meaning it wants you to leave once you have found someone. Bumble says it wants its members to find meaningful and authentic relationships. Both are reasonable starting points for a man who is serious.

Neither one promises that the women on it want the same thing. The app decides who you can meet, and your photos and your lines decide whether she agrees to meet you.

Big city or small town

A country list is not a map of your city. An app can run in South Africa and still be thin where you live.

A man in a large city has more people to sort through, so each app is easy to judge in a couple of evenings. A man in a smaller town may see the same faces within a week and need a second app sooner.

a dating coach's point is that app choice depends on where you are. He says Tinder is almost the only app people use in parts of Europe and works well there, while in the United States it has many fake profiles and Hinge tends to be better. He gives no answer for South Africa, and the method is the part that carries over: test where you actually live.

Run it as a two-week test

a dating coach's standing advice is to test, tweak and test again. Treat your page like a small piece of marketing and watch the result.

Give each app two weeks with the same photos and the same lines. Count how many conversations you started, how many reached a plan, and how many turned into a date. Change your lead photo and count again. The app that produces more dates for the same effort is your best app, whatever any list says.

He also warns against liking every woman you see. An app reads how selective you are, and a man who likes everyone looks less attractive to its sorting and gets shown fewer of the women he wants. Be choosy.

Keep the date near you

A woman who lives far from you is a pen pal, not a date. a dating coach's first rule for online dates is to put the date near your own place, and he says that matters more than the venue.

When she tells you where she lives, check the real travel time against yours before you build a conversation on it. Suggest a drink near you within a handful of texts. If she is too far, say so kindly and move on.

Free or paid

All four can be used for free at a basic level, and each sells paid tiers on top. Start free. Pay only when a limit is clearly holding you back, such as a daily cap you keep hitting while good women are still on screen.

A paid tier shows your page to more people. It does not improve the page. A man whose photos get no interest gets passed over by more women when he pays.

Where to start tonight

Pick two apps, one for a relationship and one with a bigger crowd. Add real photos in good light, say clearly what you want, and ask a woman out within a few texts. After two weeks, drop the one that gave you less.

Keep your address and workplace to yourself early on, be careful with anyone who wants to leave the app fast, and never send money to someone you have not met.
