Not as far as Tinder says. The purple lightning bolt in Tinder's Boost pages is something you see in your list. Nothing in those pages describes a label on your profile that tells other people you are boosted. A Boost makes you one of the top profiles in your area for 30 minutes, with up to 10 times more profile views. The only thing a woman can notice is that your card turns up in front of her, and she has no way to tell why.

What the bolt is

You start a Boost by tapping the purple lightning bolt icon on the main screen. After that, Tinder says the same icon shows up in a second place: when you match with someone while the Boost is running, you see a purple lightning bolt by that match's name.

So the bolt is a marker for you. It tells you which of your matches came during the Boost. Tinder's help pages describe it as something you see on your own matches and say nothing about it appearing on your profile for anyone else.

What she sees

As far as Tinder's pages describe, she sees an ordinary card. Your photos, your bio and the rest of it, the same as any other day.

The list of fields you can edit points the same way. Tinder lists photos, bio, interests, pronouns, height, relationship goals, languages, job, school, city, gender and sexual orientation. A Boost badge is not on that list.

If you want to be sure, the test is easy. Ask a friend with an account near you to look through the cards while your Boost is running and tell you whether anything on yours looks different. A friend looking at the real screen will spot a label faster than any help page can describe one.

Does boosting look desperate?

Most men who ask this question are really asking whether paying for extra views makes them look needy. The worry comes from a fair instinct and points in the wrong place.

A woman who sees your card judges your photos and your words. She is not auditing how you got in front of her. A man who looks good and reads well does not look desperate because he was shown to more people, in the same way a restaurant does not look desperate for being on a busy street.

a dating coach names this attitude as a hindrance. In the world of men learning dating, he says, there is a strong bias against paying for anything, the guy who never buys a drink and calls it integrity. His view is that this feeling is morally pure and gets you less. Paying for a feature to be seen by more people is not supplication. The thing that reads as needy is on the card itself, not in how it got there.

What shows on your profile instead

Every extra view in a Boost lands on the same page, so the page is the thing worth looking at first.

Check the lead photo. It should be recent, clear and obviously you, with your face easy to read in a small frame. Check that the other photos show different places and days. Then read your bio as a stranger would. A line she can answer in one sentence beats a list of what you like.

Fill in the fields Tinder gives you, too. A job, a city and a couple of interests give her something to open with, and an empty card gives her nothing. You can get most of the way with an honest hour and a friend who will tell you the truth, and if you would rather have the whole page rebuilt for you, that is a job someone else can do.

Getting the 30 minutes right

Start a Boost when you can stay on the app for the whole half hour, ideally in the evening when more people are around. Have a first message in mind before you tap the bolt.

When matches come in, answer them while the Boost is still running. A woman who matched with you ten minutes ago is more likely to be looking at her phone than one who matched at breakfast. Tinder says a Boost does not promise a match, so keep your expectations level. It gives you a wider audience, nothing more.

When to skip it

Skip a Boost when your page is not ready. Ten times the views on a weak card is ten times the passes. Skip it in a week when you cannot chat, and skip it if the only reason you want to do it is to feel like you are doing something.

If you do run one, write down how many matches you got and how many answered. That is the number that tells you whether it did anything. The badge question has a simple answer, and the more useful question is whether the people who saw you had a reason to stay.
