Yes, in two separate ways. The first happens inside your own account: what an app shows you shifts as you and everyone near you like and pass. The second happens to the app itself, because the companies change how they pick people to show. Tinder and Hinge both describe the first kind in their own help pages, and both describe features that change what you see. The habits that work stay the same through all of it.

The first kind: it adjusts to how you use it

Tinder says the most important factor in its algorithm is using the app. It prioritizes potential matches who are active, and active at the same time as you.

It also says it weighs several things. Those are distance, age and gender preferences, and the interests and lifestyle details members add to profiles. They also include photos similar to ones a member has Liked before, and how often profiles are Liked or Noped.

Tinder adds that it is constantly honing the potential matches users see, based on how often their profile and all profiles in their area are Liked or Noped. That sentence is the plain answer to your question. What you are shown is not fixed. It moves as the area around you moves.

So if a spell of good results fades, the app may not have turned on you. The women near you, and what they have been liking and passing on, may have changed.

The second kind: the app changes its method

Apps also change what they do, and they say so.

Tinder says it has an AI-powered way of matching, offered in select markets. It uses your profile, your answers to questions and, if you choose, tags from your camera roll photos to put together personalized Daily Drop recommendations. Tinder also says you can view or delete the insights it uses.

Hinge describes its Most Compatible suggestion as based on mutual preferences, recent activity, and shared tastes in who you and others tend to like. Hinge says each suggestion expires after 24 hours. Its Discover feed, Hinge says, is populated with recommendations based on mutual interest.

Different apps use different mixes, and each mix is a company's choice that it can revise. The details above come from the apps' own descriptions, so treat them as the apps' own account and not as proof of how any one feed behaves.

What has changed in practice

a dating coach gives a good example. In the early days of online dating, a man could swipe right on everyone and it did reasonably well. a dating coach says that does not work on most apps now. His explanation is that an app watching you like every woman it shows you reads you as unselective, and often reads unselective as less attractive. An app with no reason to think you are picky has no reason to show you the women everybody wants.

That is a change in how apps respond to behavior, and it cost the men who kept using the old method. It is also a reminder that a trick which worked once can quietly stop working.

Another change is money. a dating coach notes that Tinder started out free and then needed to make money, as every app does. Paid features tend to put you in front of more people, because a business looks after the members who pay.

What a man can do about it

Do what holds up whatever the app changes.

Be active, in small regular amounts. Tinder says activity is the most important factor, and an account that sits unopened is not being used.

Be selective. Like the women you would actually want to meet. That keeps your history honest, and it is the opposite of the auto-swipe habit.

Keep your photos and your written answers strong. Tinder says it weighs the details members add to profiles, and photos similar to ones you have Liked. A clear, accurate set helps under any method.

Watch your own numbers. a dating coach treats online dating as a series of steps: how many women see you, how many like you, how many reply, how many give a number, how many meet. If the first step drops, the app may have shifted. If likes arrive but replies do not, the problem is your first message, and no algorithm caused it.

How to tell which one it is

Compare two weeks. If the number of women who like you falls while your pictures and habits stayed the same, the app's method or your local pool probably moved. If your likes are steady and your dates are rare, the weak step is later, in how you write and how you move toward meeting.

That sorting matters, because the first is partly out of your hands and the second is entirely in them. Spend your time on the second.

A last point on chasing the algorithm

Men burn a lot of energy trying to guess a ranking. Most of that energy is better spent on messages that get replies and plans that get made. An app can change the first step overnight. It cannot stop a woman from saying yes to a good invitation.
