Algorithms behind Tinder success
The aspiration to build a Tinder clone doesn't fade over the years. Obviously, that's due to its stunning popularity. Just take a look at the figures below:

The statistics are quite impressive. So you may be interested what makes the dating app like Tinder so in-demand. First of all, Tinder functionality is really simple for users. Actually, it lies in swiping right and left for liking or skipping a particular person respectively. In case the other person returns the affection, Tinder creates a match.
Tinder is open for the integration with Instagram. Users can access the Instagram profiles of their matches. Note that Tinder supports logging in with user's Facebook account. So users can see whether they have common friends, common interests and favorite places.
Techniques that make a Tinder app popular
Despite the fact that the Tinder functionality may seem very simple at first glance, it hides fairly complex algorithms invisible to users. Consider the following peculiarities when you create Tinder-like app:
Users can see only one person at a time but there are thousands of users swiping left and right simultaneously;
Each user (or, at least, particular groups of users) sees people in a different order. It means that the developer's task is to structure the profiles into different groups;
Attractive and unattractive people are intentionally mixed up and shown to diverse users with non-repeatable frequency;
A specific algorithm must be in charge to define who, when, and to whom should be shown to create a match in applications like Tinder.
The logic described above should be implemented on the server side of the application. The backend can be made with a help of PHP, .NET, Java, Python, or other server-side technologies. In this matter, you should approach with a great care to the choice of the server-side Tinder app developer.
Tinder app features and Technologies in use
The above algorithms are not the only points which you should pay attention to when considering the cost of creating an app. Tinder has many other functions. Their implementation requires a certain amount of time and money. Let's look at them one by one.
1. Authorization and user profile
To build an app like Tinder, you should use a Facebook authorization engine. It is usually implemented via an open authorizations protocol, like OAuth. The registration is implemented so that the app itself does not remember the login and password of the social media account (in our case - Facebook). However, it uses these credentials to create a new account within the application. Another way to log in is using the phone number. To make your own Tinder app, you can go further and use any of the existing kinds of user authorization.
Profile editing is implemented via the client-server sides of the application. On the client side, the user enters/edits the data (gender, bio, photos). On the server side, appropriate records are saved. Tinder has invented something unusual, check it out!
Tinder allows creating a Web profile so that it could be found even by the users beyond the application. When clicking 'Like me on Tinder' button the user is redirected directly to the application or to the Google Play Market / Apple App Store in case the application is not installed.
The mechanism of the implementation is as follows: the client side sends a request to the server. The server remembers that the user wants his photo to be seen when clicking the link. The server generates the link and shows the photo to everyone who clicks it.
This is how Tinder works with users and their profiles. Try to use the same approach when you create an app like Tinder.
2. App settings and notifications
Like any other app, Tinder allows adjusting the appropriate setting for the convenience of usage. For example, you can enable or disable the notifications as for the creation of new matches, receiving messages, likes, super likes. You can also choose preferable units of measurement for displaying a distance (km or mi).
Receiving notifications can be implemented via the interaction of your application with Apple / Google servers. The device where the app is installed is registered on the appropriate OS server and gets a certain ID. Afterward, the app server supplies the app with the push notifications if they come. To enable push notifications in your Android app use FCM (Firebase Cloud Messaging). For iOS app refer to APN (Apple Push Notifications).
Along with usual settings described above you can adjust Tinder-specific settings, like enable/disable discovery so that the others could or could not find you, choose to show men, women, or both, specify the search distance and the age range of the users to be found. So, when you make an app like Tinder, ensure users to get notified properly.
3. Geolocation and Communication
Geolocation is the basis of the application. Without it, the app would be useless since it is all about finding people near you. Use Google / Apple Locations and Maps services to integrate the geolocation into your Tinder-like app. For Android, you are going to employ the classes of android.location package and the MapView class, for iOS - the CLLocationManager Class and Map Kit framework.
In Tinder users can chat with each other only when they have mutual likes. Otherwise, the chat is disabled. As a rule, this function is implemented via the RESTful API or through HTTP. Permanent socket connections are not involved in order not to overload the server. The polling interval is set up depending on the frequency of the messages being sent.
Users can connect their Tinder profiles with Instagram so that the recent Instagram photos to be available on Tinder as well. Tinder content does not go to Instagram, though.
4. Monetization: In-app purchases
Users can buy a paid subscription and get more functions on Tinder, like change their location, rewind the last swipe, and turn off ads. In-app purchase is integrated via the In-app Billing API for Android applications and Store Kit framework for iOS ones.
Now you have an imagination of how to make an app like Tinder. However, the list of app features cannot display the whole list of costs needed to build Tinder app. Visible options are just a tip of the iceberg. Do not forget that you should implement such important things as the database structure, data access object (DAO) layer, Rest API, etc.
