Rewind is the yellow arrow icon on Tinder's main screen. Tap it and the last person you swiped on comes back, so you can change your answer. It only works for subscribers, and Tinder lists unlimited Rewinds as a Tinder Plus feature.

What to look for on the screen

The button is on the main screen, the one where people appear one at a time for you to like or pass on. Among the buttons there, look for the yellow arrow. That arrow is Rewind.

It is easy to overlook if you swipe with your thumb and never tap the buttons at all. Once you know which one it is, you will spot it every time.

What a tap does

Tapping the yellow arrow brings back the profile you just swiped on. Tinder says Rewind takes back your last Like or Nope, and subscribers can also take back a Super Like.

So the button works in both directions. If you passed on someone you meant to like, she comes back and you can like her. If you liked someone by accident, she comes back and you can pass.

It only goes back one step. Rewind returns your last swipe, not the one before it. If you want it, tap it straight away, before you swipe on anyone else.

Who can tap it

Rewind is limited to subscribers. Tinder lists unlimited Rewinds as a Tinder Plus feature, so on a free account the arrow will not bring anyone back.

Tinder also notes that Rewinds may be offered on a test basis in certain markets. What you see can depend on where you are.

When a Rewind is worth using

The right time to tap the arrow is when you know you made a real mistake. You meant to like her. Your thumb went the wrong way, or you were moving too fast and realized half a second later that she was exactly your type.

That is the case Rewind exists for, and it is worth using without a second thought. A woman you genuinely wanted to meet is worth one tap.

The same goes for the opposite slip. If you liked someone you did not mean to, tap the arrow and pass. A match you never wanted leaves you two bad choices: write to a woman you are not interested in, or leave her waiting on a message that never comes.

It is not worth tapping to take a second look at everyone you passed on "just in case". If you passed on her after actually looking, trust that. Going back over your own decisions one at a time turns a fifteen-minute session into an hour and leaves you with the same result.

If you reach for it all the time

If you find yourself tapping the yellow arrow several times in a single session, the button is telling you something. You are swiping faster than you are deciding.

a dating coach's read on the apps is that fast, unselective swiping works against you. The apps seem to treat a man who likes almost everyone as a less attractive one, and they have little reason to show him the women he wants. When his students stopped right-swiping on everybody and started choosing, they got better results.

Choosing takes a few seconds per woman. Look past the first photo to the rest of her set. Read what she wrote. Then decide. A man who swipes that way almost never needs Rewind, and when he does, it is for a true slip rather than a habit.

My point about paid features fits here too. He is in favor of testing them, but he warns that they multiply your results, and multiplying zero still gives you zero. A subscription that gives you unlimited Rewinds will not help a man whose photos are not getting likes back. Fix that first. The extras are worth testing once you are already getting matches.

Put the saved effort into your matches

The real value in Tinder is not in the swipe screen at all. It is in the conversations that come after it.

a dating coach keeps his app time to two short blocks a day and spends it in a set order. First come the women closest to a date, where he pins down plans. Then come new matches he has not written to yet. Only after that does he go back to swiping for more people. By his account, he swipes every few days rather than every day.

That order is the best answer to a missed swipe. One woman you passed on by mistake is a small loss. A woman who matched with you and never got a message is a bigger one. So by all means tap the yellow arrow when you slip, then get back to the women already waiting for a reply. Keep your first message short, make it about her, and aim the conversation toward meeting in person.
