Imagine a day without the internet. No browsing to important emails, attending business meetings online on Zoom, Microsoft Teams, or Google Meet, not being able to message anyone on WhatsApp, and no access to your favorite social media platforms. 

Life would not only sound boring and monotonous but also put a halt to your work life. Because of the normalization of internet use, telecom operators have made the data plans economical. However, these mobile data plans also come with a daily limit. Additionally, if you need a large amount of mobile data, it will be heavy on your pocket, especially if you are in roaming mode. 

That’s where the role of a nearby Wi-Fi connection finder app comes into play. Using such apps, you can detect the Wi-Fi networks in your range, check their bandwidth, and connect securely.

Let’s understand this with an example. For instance, you are on a holiday or vacation for personal purposes or business meetings. You might be in areas where your mobile data providers don’t offer network connectivity. In such a scenario, you not only need the internet to access emails, chat, or browse social media feeds, but also to search for the best places to visit, hotels, restaurants, cab booking, and exploring relevant routes. 

What does it mean? Separating yourself from the world of the internet? No. Fortunately, there are several cafes, bars, restaurants, malls, airport lounges, etc. that provide you with free Wi-Fi connectivity. It helps you to stay connected to the online world even if your mobile data doesn’t work or you lack high-speed internet. 

But the question is, how will you find out the nearby public Wi-Fi spots? There must be a solution that can come to your assistance using which you can scan for all the Wi-Fi networks in your area. You got it right. Some companies have opted for Wi-Fi finder app development, to make things easier for you. 

You might think that you already have the Wi-Fi feature built-in on your smartphone. However, this feature is a traditional way of finding nearby networks. Also, you only get the basic functionalities. You will only get the closest networks, most of which will be protected by passwords. You are very likely to connect to the internet successfully. 

To get rid of these limitations or shortcomings of the built-in Wi-Fi network feature, you should download and install a mobile app that can scan all sorts of Wi-Fi hotspots nearby. 

In this exclusive write-up on public Wi-Fi finder app development, let’s understand exactly what is a Wi-Fi finder application, what does it, its features, the top apps in the market, how these apps earn, how to develop a Wi-Fi locator app, as well as the cost involved in development. 

What is a Wi-Fi Finder App?

A Wi-Fi finder is a mobile app based on Android or iOS that helps users scan and find internet hotspots in nearby public places. 

But what is so different about these apps? This can be done using the built-in Wi-Fi feature on your smartphone. The answer is that along with detecting the hotspots with active internet connectivity; these apps also provide you with the password to connect to the hotspot. 

What it means is that you can use free internet by entering passwords for public hotspots of your choice or the ones that offer high-speed internet. 

Along with the basic connectivity details, the Wi-Fi locator apps also tell you a lot more information about the hotspot. This includes the level of security, brand, strength of the signal, channel, etc. Based on these details, you can decide which Wi-Fi hotspot is the best option for you in terms of both internet speed and security. 

Now you might wonder how these apps know the credentials of Wi-Fi connections in public places. So, what happens is that generally, these apps have a large audience base and work on a crowdsourced model. It means that if someone knows the password of a public Wi-Fi network, they can add or update it to the database of the Wi-Fi locator app. As a result, you can connect to most of the password-protected Wi-Fi hotspots near you. 

There are several other benefits of using a free Wi-Fi network finder app. For instance, you get the feature to download Wi-Fi maps on your device. It means that you can access or navigate to the nearby Wi-Fi hotspots even when there is no internet connectivity. 

What Does a Wi-Fi Locator App Do?

The role of a public Wi-Fi locator app is to offer you the details of all the nearby wireless networks. These details are shown to you in a user-friendly or easy-to-understand manner so that even a layperson can connect easily and make use of the free internet. 

The depth of information provided and the size of the database varies according to the app you use. Some apps might have credentials for public wireless networks in 10 cities, whereas others might have the same in 100 cities. 

Since these mobile applications provide you with the credentials and information of a protected Wi-Fi network, such a question is obvious: “Is it legal to use or develop a Wi-Fi locator app?”

Yes, Wi-Fi finder app development is legal, along with the use of these apps. 

However, there are always pros and cons of everything or any tool. The same is true for these apps. It is because some people might use a Wi-Fi connection for fraudulent purposes, the passwords for which were found using a wireless network finder app.

The users can see the details of the access point details of the network they can connect to. These details can include the channel information, data transmission rate, vendor, frequency band, etc. 

Graphical Charts

The details of the network can be represented in the app in the form of graphs for better understanding. For example, the speed of the internet can be shown fluctuating with the live and real-time charts. 

Frequency Bands

When users can see the frequency of the network, like 2.4 GHz or 5 GHz, they can understand which are the least occupied channels and which ones are the most occupied. 


Comparison of Access Points

In the graphical charts, you can show a comparison of the nearby Wi-Fi channels in terms of speed, occupancy, etc. It helps users analyze which channel is the best for them. 

Import CSV

This feature allows the users to export the historical data of a network or access point as a CSV file to review later. They can also export the active visualization data into PDF. 

Upload/Download Speed

Users should be able to see the speed of download and upload with a specific Wi-Fi network nearby. This helps them to see whether a connection is worth it for them or not. The speed can be shown in the MBPS format. 

Signal Level Strength

Along with speed, the nearby Wi-Fi finder app should also show the strength of the signal. It is usually measured in decibel milliwatts (dBm). With measurement in dBm, also show whether it is poor/low, medium, high, etc., for improved user experience. 

Filter by Venue Type

This feature is meant to help users apply filters on the type of venue and see only relevant networks. For instance, the venues can be a hotel, restaurant, bar, cafe, store, etc. Users can decide if they wish to connect with a specific wireless network. 


Once a user has connected to a Wi-Fi network and used it, it should be saved automatically. So, when the next time a user comes in the range of this network, the connectivity happens without any manual action or the need for entering a password again and again. It’s a great feature for a better user experience. 


This is one of the most important features of a nearby Wi-Fi network finder app. The role of the Community is to allow the users to add or share the passwords of the new networks they know but are not available on the app. 

For example, if a user knows the password of a cafe nearby his home, they can add it to the app. So when new users of the app come into the range of this cafe, they can connect to the network. 

Offline Maps

Another essential feature to integrate during free Wi-Fi finder app development is the Offline Maps. It helps users to download the maps in offline mode and access the nearby hotspots in an area even when they are not connected to the internet. 

Wi-Fi Hotspot Rating

After using a particular Wi-Fi hotspot through the app, the users should be able to rate their experience with the connection. If they found the connection unstable, poor, or not secure, they can rate it below average. On the other hand, they can rate it as excellent if the network met their expectations.

Eventually, it helps other users to see the rating of a network while exploring the nearby hotspots and make better decisions quickly. 

Data Usage

To help users track their Wi-Fi data usage, the application should have this feature. It can show the total amount of data consumed by the user in the last 24 hours, weekly, monthly, etc. 

Data Security

The users will lose trust in your app if the data transmitted over the network is not secure. Moreover, it can lead to a bad reputation, which can eventually result in loss of business. Hence, your app should follow some Wi-Fi security best practices. 


If you are offering the application with a subscription model or in-app purchase where the services come at a cost, then you must provide support to the users. In case they face issues or glitches, they should be able to reach out to someone and seek support. 

Password Sharing

Users should have the feature to share the passwords of a specific Wi-Fi connection with their friends or co-travellers. 


Another important security feature to integrate during Wi-Fi locator app development is support for network encryption protocols, like WEP, WPA, WPA2, or WPA3. 


It can be added with the filter feature or as a standalone feature. Sorting allows users to see the list of available networks with a ranking on the basis of speed, strength, frequency, etc. 


The integration of a virtual private network (VPN) within the application accelerates internet speed and makes the connection more secure. A great feature to add to your app to gain an edge over the competitors. 

Payment Methods

For in-app purchases or subscriptions, users will need to pay for certain services. For this, you should integrate multiple payment gateways so that they can make payments with the method of their choice. For instance, you can go for eWallet application development, UPI, PayPal, credit/debit cards, net banking, etc. 

Auto/Manual Wi-Fi Turn Off
