How To Build an App Like WeChat?

Wechat App

At first glance, the Chinese app WeChat seems similar to its Western counterparts like WhatsApp and Viber. It allows users to text people over an internet connection, share photos, videos, and other files.

If we dig deep, though, we will find a full-featured app that does so much more than just messaging, especially for residents of China. It is more akin to a blend of messaging, social gaming, and social media.

What is Wechat and how did it Start?

WeChat, known as China’s “App For Everything,” is a social media mobile application software developed by Tencent. It was first released in 2011, and by 2017, it was one of the largest standalone messaging apps with more than 963 million monthly active users. According to Techinasia, in 2017, WeChat started to develop an AR platform for its ever-expanding services. WeChat’s AI team is working on their own 3D rendering engine to create realistic appearance on detailed objects, in smartphone-based AR apps. They’re also developing a simultaneous localization and mapping technology, which helps calculate the position of virtual objects relative to their environment, enabling AR interactions without the need for markers, such as QR code or a special image.

Essential Features For a WeChat App

Live Chat

WeChat allows users to send free texts, pictures, voice and video messages, as well as to make free voice and video calls. This feature also provides group chat functionality, broadcast messages, and walkie-talkie mode.

WeChat can exchange contacts with nearby people via Bluetooth and provides various features to contact people at random if desired. It can also integrate with other social networking services such as Facebook and QQ.

 

Chat using your computer

WeChat hasn’t let this opportunity slip through their fingers, having implemented a version for chatting directly in your browser.

 

Official accounts

If you want to use WeChat for business, you must have a solid grasp of WeChat official accounts and how they work. Official accounts provide a formal way to interact with your followers and customers through WeChat.

There are several types of WeChat official accounts:
  • WeChat Subscription accounts
  • WeChat Service accounts
  • Enterprise accounts
  • WeChat mini-programs

Once you specify a type of account, it cannot be changed. By the middle of 2017, the number of WeChat official accounts had reached 10 million. Official accounts of organizations can apply for verified, official, public accounts. Official accounts can be used as a platform for services such as hospital pre-registration, visa renewal, or credit card service.

 

Built-in photo editing

Do you want to edit your photos to be published on social networks? Or maybe you want to add a filter to your profile picture on WeChat? This is all possible in WeChat without using external applications. The app has integrated photo editing, allowing you to edit photos with a whole host of different filters.

Moments

What is a WeChat moment? Moments is an essential part of WeChat that allows users to post images, texts, and comments, share music and articles, and “like” stuff. Moments can also be linked to Facebook and Twitter accounts, which can automatically post Moments content directly to these two platforms.

 

WeChat Pay

WeChat Pay is a payment feature that allows users to complete payments quickly and easily with their smartphones. You can increase your balance by linking your WeChat account to a debit card or by receiving money from other users. WeChat Pay can be used for digital payments, as well as payments to participating vendors. As of March 2016, WeChat Pay has more than 300 million users worldwide. In 2017, Tencent reported that WeChat had overtaken Alibaba with 600 million active WeChat mobile payment users versus 450 million users of Alibaba’s Alipay.

Send some Bitcoin

Half a million people used OKCoin’s mobile wallet and WeChat account – called OKLink – to gift bitcoin to their friends in 2015. Users sent the bitcoin gifts in the form of virtual red envelopes through WeChat.

 

WeChat Mini Programs

Mini Programs is a WeChat feature that essentially allows you to access light apps within WeChat without having to download or install brand new apps.

During the WeChat Conference 2018, WeChat released these data about WeChat Mini Program:

  • By Jan 2018, developers published 580,000 Mini Programs
  • Mini Programs attracts 170 million Daily Active Users
  • More than half of the user traffic is from one single game Tiao Yi Tiao: 100 million DAU
  • 50% of WeChat Mini Program users are from tier 3 or lower cities
  • The game Tiao Yi Tiao is able to attract 50% of female users

Mobike

This bike-sharing program allows cyclists to pay for rides using their WeChat wallet. It is similar to bike-sharing schemes in cities worldwide aside from one difference: it does not require docking stations.

Bikes can be parked anywhere within major cities, which admittedly has created some difficult pick-up points. Mobike is not owned by Tencent, but the functionality resides within the WeChat app.

 

City Services

WeChat has launched the City Services feature in more than 27 cities across China, including Beijing, Shanghai, Guangzhou, and Shenzhen. City Services include booking doctor appointments, paying electricity fees or traffic fines, and booking transportation.

The City Services section also includes traffic camera feeds, the option to pay your home electricity bill, book long-distance transportation, monitor air quality, pay traffic fines, report incidents to police, and more.

 

Hail a cab and pay for it with WeChat pay

This works for both taxis and cars at China’s top on-demand startup Didi Kuaidi. You don’t need to use the Didi Kuaidi app- it can all be done inside WeChat.

 

Heat Map

In certain major cities—including Beijing, Shanghai, and Chengdu—users can input their location to see a heat map, which measures foot traffic in a particular location. The app also provides data about crowd density in the area throughout the day and the prior week.

Enterprise WeChat

For the purposes of work and communication within companies and businesses, a special version of WeChat called Enterprise WeChat was launched in 2016. The app allows employees to separate work and private life. In addition to the usual chat features, the program lets companies and their employees keep track of annual leave days and expenses that need to be reimbursed. Employees can ask for time off or even clock in to show they are at work. Security has been upgraded and companies must register before their employees can use the service.

 

WeChat mini-games

WeChat mini-games are simply WeChat mini-programs used for gaming. Just like you can turn your shop into a mini-program shop, you can also turn your game into a mini-game.

There are already plenty of mini-games already available: simple “flash-style” games, chess, war games, and more.

Finding Friends

WeChat allows people to add friends in a variety of ways, including searching by username or phone number, adding from phone or email contacts, playing a “message in a bottle” game, or viewing nearby people who are also using the same service. In 2017 WeChat added a “Shake” function.

Shake is a feature that allows you to meet random people not too far from you. You can choose to chat with the person or “shake” again to get another random person. All you have to do is go to the Discover tab, tap the Shake button and start shaking your phone.

WeChat Index

In March 2017, Tencent released a new feature of WeChat: WeChat Index. WeChat Index is a tool that tracks trending keywords in 7, 30, and 90-day segments, which is useful for those interested in knowing what 898 million users are talking about. It is worthy of note that WeChat articles are not currently indexed by Baidu or Google and can only be searched on Sogou.com.

 

News Feed and Search

In May 2017, WeChat has acquired a news feed and search functions. The Financial Times defined it as a “direct challenge to Chinese search engine Baidu,”.

WeChat Out

WeChat Out is a VOIP feature that allows users to make low-rate calls to mobile phones and landlines around the globe. The feature involves purchasing credit within the app using a credit card.

Here is a day-in-the-life video of a typical WeChat user that demonstrates how its features have become essential in everyday life in China.

 
 

What is the WeChat technology stack?

So how is a chat app like WeChat created? Start by understanding the tech stack, which goes into it first. Here’s what the WeChat team has used:

WeChat uses Ejabberd, IceWarp, iChat, Openfire, and Prosody servers to process hundreds of thousands of messages instantly with little to no delays. This application server pairs perfectly with the Erlang programming language, which powers the entire app. It may not be the standard choice, but this language is rather flexible and allows quick and instant fixes to be made without much refactoring. However, you are not obliged to use the same language for chat app development. For instance, the Telegram instant messaging app uses Node.js for all backend coding.

Originally WeChat used HTTPS to transfer all of the users’ messages.

The databases are powered by EnMicroMsg DB and SQLCipher. The WeChat app is available for Android, iPhone, BlackBerry, Windows Phone, and Symbian phones. Web-based OS X and Windows clients also exist. This, however, requires the user to have the app installed on a supported mobile phone for authentication, and neither message roaming nor “Moments” are provided.

How do WeChat-like apps make money?

How do free apps like WeChat make money? In recent times, we have been getting many questions about the hottest topic on the app market. Well, it’s time to reveal the truth behind app monetization magic.

 

Advertising

Advertising is a core money-spinner. WeChat makes more than $1.3 in advertising revenue from each user, according to Arete Research analyst Muzhi Li.

Value-added services

Many WeChat services are free. Tencent Company launched a sticker shop and game center in WeChat to provide value-added services, which are a key revenue source for Tencent’s other popular platform QQ. These services normally charge $0.99 for each purchase.

Other

Since March 2016, WeChat began charging users 0.01% to withdraw funds from their WeChat wallet but not to transfer within the ecosystem. This fee is now levied on digital transfers to bank accounts where the sum exceeds 1,000 yuan (US $153), the company said. The minimum fee per transfer will be 0.1 yuan. Tencent CEO Pony Ma said the fees of 0.1% of each transaction totaled more than RMB 300 million in January 2016.

 

How much does it cost to build WeChat?

At this point, you should have a somewhat well-rounded understanding of what features you would like to develop and whether you plan to hire a development team locally or outsource the entire project.

Essentially, WeChat can be used for just about anything you want to do online. It does facilitate easy integration between most of China’s most popular apps.Within WeChat, there are equivalents of Western apps like Facebook, Instagram, PayPal, Tinder, and Slack, along with hundreds of other popular services.

The total project timeline, depending on the scope of your requirements, can vary from 600 to 2500 hours. In money equivalent, that transfers to $100k and higher depending on the features and team’s hourly rates.
