Good onboarding is essential – comparing the big-5 messaging apps

Mobile messaging apps are going to dominate the web. They're already bigger than social networks, and the falling prices of mobile devices and mobile data means their growth isn't going to slow down anytime soon.

The leading messaging apps already have hundreds of millions of monthly active users and allow their customers to do much more than just exchange messages. Gradually, users are beginning to use chatting apps to connect with brands and shop for products and services. Apps like WeChat and Line are starting to monetize their user base, showing the commercial promise of chat.

Messaging apps have the tough job of not just convincing individuals to use the product, but also convincing individuals to get all their friends chatting too. While all apps are easy to use, there's often a lot of friction in getting set up—from downloading the app to getting through all the legal points. Since most people already know how to chat, user onboarding doesn't need to teach them on how to use the core functionality of the app, but instead reduce sign-up friction and build excitement.

When done right, it can be powerful in getting users ramped up and ready to spread the word to their friends.

In this article, we look at how five of the most popular instant messaging apps onboard users to engage and retain them.


After gaining popularity in Japan, Line started seeking international expansion with the view of going public. Although Line had reached over 700 million total users in 2015, there were concerns that its growth had already peaked when the app was preparing to go public in 2016.

Redesigning their onboarding flow was one of the steps the company took to improve its product, leading to a successful IPO.

Line Onboarding

How Line Onboards Users

  • Line has a product tour, but it can be skipped at any time: The app educates its inexperienced users, but allows those who know their way around to skip the tour, thus lowering friction.
  • Facebook signup makes it easy to add your information: It can pull your name and picture, thus saving you a couple of steps toward creating your profile and adopting the app into your daily life. This step also benefits Line by giving it access to additional information about users.
  • Options to add friends and to allow others to add you are pre-selected: Line's success depends on getting you to add friends and chatting to as many people as possible. The app promotes the desired behavior by taking advantage of the so-called status quo bias—it knows that you're more likely to stick with pre-selected options than change them to something else.

Facebook Messenger

Facebook wants to leverage its crushing lead in social media to become the preferred instant messaging tool.

The goal for Messenger is to be a platform where people can build and integrate apps. Facebook Messenger needs a large user base to get more developers using its open API. It also wants to be a place for individuals to connect with brands. Messenger users can already order an Uber from the app.

Facebook Messenger Onboarding

How Facebook Messenger Onboards Users

  • You can sign up with or without a Facebook account: Facebook wants to make Messenger a standalone product.
  • The app puts value first: It takes great care when explaining why it needs to verify your number, have access to your contact list, etc.
  • You can't skip the step of importing contacts: This is somewhat risky, as it might result in shooing away some users, but the step is crucial to Messenger's success.
  • Messenger wants to take over your text messages: Clearly, it wants to be the go-to app for every type of message—from chatting to your Facebook friends to texting your family on your way home from work.


WhatsApp is one of the apps that has defied all sorts of expectations—it has done many things contrary to what common sense in mobile design dictates and has managed to build a formidable user base leading to a record acquisition by Facebook.

However, WhatsApp's user onboarding flow is very conventional, taking just the appropriate steps to guide users to the value it has to offer.

WhatApp Onboarding

How WhatsApp Onboards Users

  • Well-designed legal opt-in: WhatsApp doesn't overwhelm users with legalese and technical language on the first screen.
  • Strong value-driven explanation for why it needs access: At every step, the app does an excellent job of explaining why it needs access to users' contacts, photos, and SMS. The copy on the modal windows describes the action as benefits users can gain by approving each step.
  • WhatsApp uses SMS as a way to simplify phone verification: Not only does SMS simplify the verification process, but the automatic detection of the SMS by the app saves users the nuisance of having to dig through their phone messages. The automation of this step, moreover, ensures that users never have to leave the app during onboarding, thus minimizing the chances that they get distracted by something else on their phone and never come back to complete their signup.
  • Well-designed options to re-send the SMS or verify through a call: They don't get in the way unless you need them. The countdown timer next to each option also gives you a subtle indication of how long it may take to receive your original code.


Viber often flies under the radar, but the app has an impressive user base that stands at over 800 million users. In addition to connecting users with brands, Viber also offers fan-driven Public Accounts and a nifty “Secret Chat” functionality. The company was acquired by Japanese ecommerce giant Rakuten for $900 million in 2014.

Viber Onboarding

How Viber Onboards Users

  • All permissions requests are grouped upfront: This risks overwhelming users with too big an ask before they've seen any value from the app. However, once the app gets passed this hurdle, the onboarding is much easier for users.
  • Phone verification process is straightforward: Every screen makes it very clear what should happen next, and whether the user has to do anything or not.
  • Once you've created your profile, Viber suggests four friends who're already using the app: Research has shown we can perceive up to four objects at the same time. Viber takes advantage of this finding by showing users limited options to increase the chances that they start using the app.


WeChat is perhaps the most successful example of an instant messaging app and one that many other brands, including giants like Facebook, are looking to replicate. WeChat is not only successful in picking up users—the app is closing on 1 billion monthly active users—but also in allowing users to complete purchases offline through their WeChat account. As a result, over 200 million people use WeChat to shop online and in physical stores, pushing the average revenue per user for the app above $7.

WeChat Onboarding

How WeChat Onboards Users

  • Instructions come in a message: Not the perfect tactic for onboarding users—mostly because the messages are too lengthy—but the format educates users about the product in a practical way. When users have a message waiting when they first log in, they can immediately start using WeChat.
  • Find someone to chat to right away: After registration, a tooltip drives users to add their friends. WeChat users can also search for people nearby. Users can also physically shake their phone to get paired with other users looking for a chat buddy at that moment.
  • Start using WeChat immediately: By allowing users to connect with others right away, even if they happen to have no friends on the app yet, WeChat lowers the possibility that users abandon the app before discovering the value it can create for them.

Retention Starts with Onboarding

In instant messaging apps, the onboarding flow has to achieve two primary goals:

  • Help users discover the value of the app as quickly as possible
  • Get them to add as many of their friends as possible so they can start chatting

Apps that get their users to complete these steps create strong network effects. This is important for messaging apps, given the existence of multiple alternatives and virtually no switching costs.

When you create a large enough network, users will find it very difficult to abandon the app that all their friends are using. A good onboarding experience can get users hooked sooner rather than later and expedite the network effect.

Product Design

The ‘Product’ is the website, service, application, interactive thing being worked on by the business. The practice of Product Design is similar in a lot of ways to UX Design. It involves the coming together of many specific design disciplines...

Call to action (CTA)

A call to action is a marketing term that refers to a prompt that invokes a response leading to a sale. When referring to a call to action (CTA) in the digital design world we usually mean the interactive element that leads to the next step in the experience - something that needs to be clicked or tapped.

User testing

User testing refers to a technique used in the design process to evaluate a product, feature or prototype with real users. There are several reasons why you might want to undergo usability testing, the most common is that it allows the design team to identify friction in a user experience they are designing, so that it can be addressed before being built or deployed.


WYSIWYG (pronounced WIZ-ee-wig) is an acronym for "What You See Is What You Get". It helps identify an an interface that allows user input resulting in an output that is rendered in a similar way. For example; a word processor application interface might resemble a piece of paper,so when printed the user can see how the output will appear.

Content Management System

A content management system (CMS) is an tool that allows a website editor/administrator to manage the content that is displayed. Websites are made of HTML and CSS to create pages. Pages can be hard-coded but would require technical development skills to make changes. A CMS usually allows a person without coding knowledge to amend existing and add new content to a website using a WYSIWYG interface.

Responsive Web Design

Responsive web design refers to a web page that dynamically adapts its layout to fit the size and orientation of the device on which it is viewed. A responsive design allows for a more optimised user experience across desktop and laptop computers as well as smartphones and tablets of varying sizes.

User Stories

User stories allow the functionality of a product or service to be expressed as written descriptions of an experience as seen from the users perspective. The writing of user stories creates a list of design and development tasks to complete in order to create any required functionality.

User Interface

A user interface (UI) is a conduit between human and computer interaction - the space where a user will interact with a computer or machine to complete tasks. The purpose of a UI is to enable a user to effectively control a computer or machine they are interacting with, and for feedback to be received in order to communicate effective completion of tasks.


A persona in UX Design is the characterisation of a user who represents a segment of your target audience. On a project you might create any number of personas to be representative of a range of user needs and desires. The solutions you design must answer these needs in order to deliver value to your target audience.

Card sorting

A great, reliable, inexpensive method for discovering patterns in how users would expect to find content or functionality. Card sorting is used to test the taxonomy of data with a group of subjects, usually to help inform the creation of the information architecture, user flow, or menu structure on a project.


A technique used to generate ideas around a specific topic. Often done in groups, but can be done individuals. The process usually involves writing down all ideas around a topic onto paper, a whiteboard or stickies often implying some kind of association.

Minimum Viable Product

An MVP is a product that has the minimum set of features to prove the most essential hypothesis for a product. Businesses building a new product can create a Minimum Viable Product to prove that an idea is viable and warrants further investment. A further benefit being that the next stage of development can be informed by feedback obtained from testing that MVP.


A sitemap is a diagrammatic representation of a hierarchical system. It usually depicts the parent-sibling relationship between pages in a website, showing how sub pages might be arranged underneath their parent groupings. This arrangement forms a map of the site.

User journey

A user journey represents a sequence of events or experiences a user might encounter while using a product or service. A user journey can be mapped or designed to show the steps and choices presented as interactions, and the resulting actions.


A prototype is draft representation built to test ideas for layout, behaviour and flow in a system. Prototypes are an indispensable tool for resolving a large number of potential issues in a concept or business before too many resources are deployed to put a design into production.


A Wireframe is a visual schematic that conveys a basic level of communication, structure and behaviour during the design of a system. Wireframes are low-fidelity designs that bypass including a detailed user interface or visual design, conveying just enough to get across the core idea.


To say something is usable is a qualitative statement about how easy that thing is to use. Usability is an assessment of how learnable a system is and how easy a user finds it to use. The usability of a system or product is a key factor in determining whether the user experience is a good one.

Information Architecture

Information architecture is the design and organisation of content, pages and data into a structure that aids users understanding of a system. A more organised system enables users to more easily find the information they require and complete the intended tasks.

UI Design

User Interface Design is the discipline of designing software interfaces for devices, ideally with a focus on maximising efficiency, responsiveness and aesthetics to foster a good user experience.

UX Design

The practice of User Experience (UX) Design is the coming together of many specific design related disciplines to improve the usability, responsiveness, uptake and aesthetics of a product or service.

User Experience

A general term that covers all aspects of a user's participation while engaging with something that has been designed. Usually when talking about User Experience in the digital design field it refers to the interactions, reactions, emotions and perceptions while using an app, service, website or product.
