Dating app opening lines: what the rules and the evidence say

Updated October 6, 2026 · 12 min read

On Tinder you write after a match. On Hinge you like one photo or prompt, and a comment on it is your opener. On Bumble, since August 11, 2026, either person opens, once, with 72 hours to reply. No published study shows which line works. What we would write: a detail, a question, something easy to answer.

We did not use the apps for this guide. We read what Tinder, Hinge and Bumble publish about messaging, the research we could find and three forum threads, and every example opener below is ours.

What counts as a first message on Hinge, Tinder and Bumble

Each app decides what a first message is, and the same “hi” lands differently in each. A Hinge comment arrives pinned to one photo or one prompt answer, prompts being the short questions people answer on their profiles, so it can be short and still specific. A Bumble opener is the only message you get to send until the other person replies.

Tinder leaves the most open. You write after you have both said yes. Our view: that is the most open start of the three and the easiest to waste, since nothing in the app asks you to say anything in particular. A list of lines that ignores which app you are in skips the part that decides how a line is read.

On Tinder, messaging opens once you match, and Platinum subscribers can send a message before matching (Tinder, 2026). The rest of the app is on our Tinder page.

On Hinge you never like a whole profile. Every match starts with a like on one part of it, you can add a comment to that like, and free accounts get eight likes a day (Hinge, 2026). Since December 8, 2025, Hinge has offered Convo Starters: when you send a like, the app shows three tips built from the other person’s profile, and you are free to ignore them. The feature started in the US and reached the UK by February 23, 2026 (Hinge, 2025). We found nothing on when it reaches other countries, Sweden included.

Bumble changed the most. Since August 11, 2026, according to Bumble, either person in a match can send the first message; before that, in a match between a man and a woman, the woman had to. Whoever opens gets one message. The other person has 72 hours to reply, up from 24, and the chat opens only once they do. A one-word opener gets a prompt from the app to add more (Bumble Inc., 2026). Bumble says it tested the change internally with members in Canada in June and July 2026, and it gives no sample size (Bumble Inc., 2026). When we checked on October 6, 2026, Bumble’s US App Store listing described the new rule: anyone can message first, and the chat unlocks on a reply (Apple App Store, 2026). Our news item on the change has more, and Hinge vs Bumble puts the two apps side by side. The profile that opener gets built from is covered in Bumble bios and prompts.

What the research says about openers, and what it does not

We found no study that tests opening lines on Tinder, Hinge or Bumble against each other. What exists sits next to the question: research on conversation, one study of emails on a dating site, and a few large datasets on who writes to whom.

Conversation research comes closest. In a 2017 set of studies, people who asked more questions, especially follow-up questions, were liked more. In online chats, the question-askers were better liked, and in speed dating they were more likely to get a yes to a second date (Huang et al., 2017). Those were live conversations, where the other person was already talking. An opener goes to a stranger who may never answer, so the finding hints at what helps an opener without testing one.

The one study of real first messages is about email. Researchers collected emails from 105 online daters and sorted the openings into seven categories and 18 subcategories. Men were more direct than women, and people who discussed what they wanted in a partner tended to report a higher likelihood of a second date (Sharabi & Dykstra-DeVette, 2019). That likelihood was self-reported, and an email on a dating site has more room than a line in an app.

For Tinder itself, the most detailed look is a decade old. In a 2016 study, Tyson and colleagues set up curated profiles, most of them in London, and recorded what came in (Tyson et al., 2016). Men’s median message was 12 characters long, and women’s was 122. A quarter of men’s messages were under six characters, room for “hey” and little else. Among the people who matched with the profiles, 21% of the women sent a message, against 7% of the men. The men who did write were quicker, with a median of 2 minutes to the women’s 38.

A preprint from the same year, meaning a paper posted before peer review, covered about two million conversations among 400,000 users in 30 large US metro areas, on a mobile dating app it did not name, with matches made from late 2013 to April 2015. Men started 79% of them (Zhang & Yasseri, 2016).

The last study is about who you write to. On a free US dating site in New York, Boston, Chicago and Seattle, over one month in January 2014, men messaged people about 26% further up the site’s desirability ranking than themselves, and women about 23%. The bigger that gap, the less likely a reply (Bruch & Newman, 2018).

Our reading: the evidence points to asking questions and to fewer replies the further up you aim. Being specific is our rule of thumb, not a finding. None of it says which line. None of it tests an opener in an app as the apps work today.

Who is reading it: the other inbox

The person you write to is either short of messages or buried in them, and from the outside you cannot tell which. Pew Research Center asked current or recent US users of dating sites and apps about it. Of those, 55% had often or sometimes felt insecure about getting too few messages: 64% of men and 40% of women. And 36% had often or sometimes felt overwhelmed by how many they got: 54% of women and 25% of men (Pew Research Center, 2023). The survey as a whole ran July 5 to 17, 2022, with 6,034 US adults.

A 2010 study of a major US dating site leaned the same way. Women stated more restrictive preferences, and they were more selective about whom they contacted and whom they replied to (Fiore et al., 2010).

The forums argue about what to do with that. In a 2022 Mumsnet thread, a woman on Bumble, where women then had to write first, asked what to write to a man whose profile listed only his hobbies, and the replies were to name one hobby, try a would-you-rather, or just write something (Mumsnet, 2022). In an undated Student Room thread, one woman said she ignores a bare “hey”, and another poster said a plain “hey” is fine (The Student Room, undated). The forum is split, and the evidence is silent: Tyson’s data shows that very short messages were common, not whether they worked.

Our reading: you cannot tell which inbox you are writing to, and a line that works in a full one costs nothing in an empty one. That is logic, not a finding.

Opening lines that work: a detail, a question, something easy to answer

Our rule of thumb has three parts. A detail from their profile shows the message was written for them. A question gives them something to do with it, which is the part of the research that carries over best (Huang et al., 2017). And easy to answer means one sentence back: a name, a place, a number, or a pick between two things.

The examples are ours, not tested at scale. Each comes with one line on why it is easy to answer.

Tinder opening lines

You write after the match, with their photos and maybe a short bio to go on.

• A sourdough loaf in their third photo: “That sourdough looks better than my local bakery’s. How many flat loaves did it take to get there?” Easy to answer: one number does it, and the story is optional.
• A bio line about Mario Kart: “Your bio says you’re looking for someone to beat at Mario Kart. Which track should I be scared of?” Easy to answer: they wrote the setup, and the reply is a track name.
• A photo on a mountain: “Is that the summit in your second photo, or the spot where the view got good enough?” Easy to answer: two answers on offer, and neither one is wrong.
• A dog in most of the photos: “Your dog looks like he has strong opinions. What’s the strongest one?” Easy to answer: it is about the dog, and the dog is in the photos for a reason.

Hinge openers

The comment goes on one photo or one prompt answer, so the detail comes built in. Openers by prompt type, and what Hinge itself claims a comment does, are on Hinge openers. Our guide to Hinge prompts covers the other side: answers that are easy to comment on.

Bumble openers

Your opener is the only message until they reply, and they have 72 hours to do it (Bumble Inc., 2026). That is our case against “hey”, and the app seems to agree, since a one-word opener gets a prompt to add more.

• A trivia night trophy in their second photo: “Trivia night trophy in photo two. Which category do you carry the team in?” Easy to answer: one word does it, and the trophy is their own evidence.
• Photos that are mostly outdoors: “I’m hoping to meet someone who’d rather be outside on a Saturday, and your photos suggest you might be. Hiking or cycling?” Easy to answer: the reply is one word, and the message says what you want up front.
• A ferry in their first photo: “Ferry in your first photo: vacation or commute?” Easy to answer: two options, no wrong one, and either leads to a second question.

When the profile gives you almost nothing

Some profiles are three photos and no words. Two moves are left: a question about the one thing you can see, or a would-you-rather, which the Mumsnet thread above also suggested. “One photo, and it’s at a wedding. Guest, or the one giving the speech?” is easy to answer because it is about the only thing on the profile and has two answers. “Would you rather spend a long weekend in a city or in a cabin with no signal?” is the fallback when there is nothing to point at, since neither side is wrong.

What to skip, including the circulating reply-rate claims

Our view: these are the parts of the usual advice that we found nothing behind.

• A bare “hey”. It is the point the two threads we read argue about most, and the evidence cannot settle it. On Bumble the stakes are higher: the opener is your only message until they reply, and the app itself prompts you to add more when it is one word (Bumble Inc., 2026).
• Copy-paste lines. The five pages we read on this topic hold lists of 37, 44, 100 and more than 180 lines, and none of them cites a study. A line written for anyone says nothing about the person reading it.
• Reply-rate numbers. Industry blogs and tool sellers say how much more often certain openers get answered, by length, by timing, or by using the other person’s name. We found none with a method behind it, meaning a sample, an app and a date, so none of the figures appear here.
• Hinge’s own numbers on comments. Hinge’s Convo Starters announcement says likes with a comment do better and gives figures for it. Hinge has the data and has not published the method, so we leave the figures out (Hinge, 2025).
• Match rates by gender. These circulate on the same blogs. The only measured figures we found come from the 2016 study of curated profiles in London (Tyson et al., 2016), which says little about your odds a decade later.

Our reading: the people with real data on which openers get answered are the apps, and none of them has published a method. Until one does, a reply-rate figure is a guess with a decimal point.

After they reply: moving to a date

A reply is where the conversation starts. The next useful message is a second question built on what they said, the follow-up that the conversation research keeps pointing to (Huang et al., 2017). The stretch between opener and date has its own guide: how to flirt over text.

Then a plan, with a day and a place. Our rule of thumb: by the third reply. Chats can run long without going anywhere; in a 2025 Mumsnet thread, one replier described a dull how-was-your-day chat on Hinge that ended in an unmatch when she asked to meet (Mumsnet, 2025). Once the date is set, our first date questions cover what to talk about.

How to use this

Our view, in five lines.

1. One detail from their profile. A photo, a prompt or a line of the bio, named, so they can see the message was written for them.
2. One question they can answer in a sentence. A place, a name, a number, or one of two options.
3. Nothing that needs a paragraph back. Three questions in one message is a form to fill in.
4. A plan by the third reply. A day and a place, so the chat has somewhere to go.
5. On Bumble, one shot, so no “hey”. The opener is your only message until they reply, and they have 72 hours (Bumble Inc., 2026).
