HTML5 apps are written with responsive design methods that scale depending on the size of the device they’re currently being viewed on overall.

When a new update is required, the app is updated and tested and is then available for all devices immediately.

In contrast, native apps are written in the native language of the device or platform’s OS (Operating system); for instance, Android runs on Java or Kotlin.

One of the central benefits of HTML5 app development is that you’re only required to build a single app for all devices–keep that in mind.

Why should I develop an HTML5 app?

Writing native apps is costly and time-consuming, and app developers with skills for writing native apps are usually in short supply.

That’s because mobile apps need constant maintenance and bug-fixing and must be updated regularly. In other words: high ongoing costs.

With HTML5, none of that is necessary; you build the app once using the power of HTML5 and then deploy it to any mobile device.

HTML5 was written with mobile in mind first and foremost and has plenty of features that developers can use.

For example, HTML5 can take advantage of geolocation, motion sensors, and virtual keyboards.

Not to mention that an app developer can write an app that will deliver lower-resolution images to mobile users on slower networks and higher-resolution images to users on faster networks.

HTML5 is more straightforward to use than the tools required to build native apps, and it takes less time to create apps from scratch overall as well.

HTML5 makes it easy to create and update apps, and you only have to maintain a single codebase and then deploy it to multiple platforms.

All of this results in a considerable amount of time and money being saved in equal measure. For certain companies, then, HTML5 is a better choice than developing a native app.

What is the HTML5 app development process?

You need to develop the best HTML5 app possible. One that loads quickly, runs smoothly, and offers an excellent all-around service.

Building an HTML5 app is about following a specific process that ensures nothing gets missed during development.

You can find a streamlined step-by-step guide to the app development process below.

1. Identify your niche

The first step to developing an HTML5 app is to select a suitable niche. You need to think about things like the type of app you wish to build, what it does, and, of course, which area you want to focus on.

2. Ensure compliance

You need to be sure you’re aware of what you’re legally allowed to do while developing an HTML5 app.

Most countries have a set of legal requirements that you must comply with, and each will typically follow safeguarding systems.

3. Competition analysis

You’ll need to analyze your competitors. Most niches are highly competitive due to the potential audience you can reach and the value you can offer.

It’s important to analyze your competitors, find out the advantages you have against them, and see how long it took them to become successful.

Doing so will put you in a much better position to be able to list the features of your HTML5 app and set out the value you offer.

4. Define your essential features

Now you need to choose the essential features for your HTML5 app.

You don’t need to cram your app with endless features, but you must create a strong solution with features that’ll make your HTML5 app more innovative and user-friendly.

Shortlist all those features you can’t imagine the app would function without, as this will provide a plan to move ahead.

5. Build an expert team

An experienced team of experts will allow you to create a great app. Most brands alone won’t have the experience to develop an HTML5 app without support.

Therefore, be sure to hire a team of developers or work with a reputable app development company with the relevant expertise. You need to be able to build a competent HTML5 app without fuss along the way.

6. Estimate the overall cost

You need to consider many factors for determining the cost of your solution, from the app’s features to legal compliances.

It’s best to estimate before starting the HTML5 app development process–you can do this by preparing your project’s scope document with a budget and timelines.

7. Produce an MVP

An MVP (minimum viable product) is the version of your app that serves as proof of your app’s concept and includes the minimum amount of features to be able to try it–it’s typically the most basic version of the app you’ll see. This is easier to achieve with HTML5 app in general.

This step enables you to get early feedback on the app and minimises the risk of your idea going wrong.

You’ll also be able to increase your app’s scope of improvement and reduce overall risk factors.

8. Upgrading, maintenance, and improving

Your app development process shouldn’t stop after the HTML5 app gets launched. Instead, keep improving and upgrading it as the feedback comes in–the process is a gradual one rather than instant.

The improvement of processes and products should be made by adopting new technologies and providing quick responses to customers’ problems–this ensures the app goes from success to success.

HTML5 app development best practices and features

Here are some of the main aspects to consider when developing a mobile HTML5 app, including best practices as well as essential and advanced features.

Encrypt your data

Encryption is the basic process of encoding information to protect it from anyone not authorized to access it.

When using app web services and APIs, you should not only implement an authentication plan, but the data across those services should also be encrypted.

Add unique app elements

While familiar design solutions offer a great starting point, don’t blindly follow an app design template–your HTML5 app design should be inviting enough to create a fresh experience.

For a unique design, you should deploy tools like surveys and ask your users what else they’d like to achieve, as well as explore competitors’ web apps and see what you could do differently to truly stand out.

Streamline app features and buttons

The best HTML5 app design balances a feature-rich design with a clean and simple user experience. Web apps often have more space constraints than regular websites, too, so keep that in mind.

Be sure to prioritize the essential features on your web app’s homepage (and basic navigation and dashboard menus) and offer other options in a separate advanced features section.

Essential features

Your HTML5 app will need to offer a line-up of essential features.

The MVP is the minimum standard to showcase your product to your target audience, and the features must meet the most essential functions of mobile apps.

These are some of the key features your app needs to have:

1. Built-in integrations

HTML5 web apps include built-in features such as web storage, WebSockets, geolocation, offline support, WebRTC, and APIs for seamless integration with modern web tech.

2. Web notifications

Web apps can send real-time alerts using the Notifications API, keeping users informed even when the app is inactive.

3. Top-notch user support

Built-in chat, FAQs, and assistants enhance customer service and engagement.

4. Fast-loading content

Caching, lazy loading, and optimized assets ensure quick rendering and smooth performance.

5. Location-based services

The geolocation API enables apps to offer personalized content and navigation based on user location.

6. Easy-to-navigate UI

Responsive design, intuitive menus, and accessibility features improve usability across devices.

7. Fast loading times

Modern web tech, such as lazy loading, compression, and efficient coding, reduce page load delays.

8. Search options

Built-in search bars and indexing enhance user experience by enabling quick content discovery.

9. Strong data protection

HTTPS, encryption, and security APIs help safeguard user data and prevent cyber threats.

10. Bright and bold colours

Modern CSS and design frameworks allow for vibrant, eye-catching visuals that enhance branding.

Focus on HTML5 app features that provide the greatest value to your customers. Collect feedback, let users tell you what features make sense to them, and then implement the changes when possible.

Advanced features

Advanced features are optional, but they allow your HTML5 app to offer value to users. Advanced app features include the following:

1. Inventory and category management

Web apps use databases and APIs to organize, track, and update products or resources in real time.

2. Map data

The Maps API enables integration with services such as Google Maps for location-based navigation and geographic visualization.

3. Enhanced audio processing

The Web Audio API provides advanced sound manipulation, spatial effects, and real-time audio editing.

4. AR

WebAR technologies and APIs allow augmented reality experiences directly within the browser without requiring additional apps.

5. Geo-tracking

The geolocation API enables continuous location tracking for personalized content, navigation, and analytics.

6. VR

WebXR and WebGL bring immersive virtual reality experiences to web apps, supporting 3D interactions and simulations.

7. AI support

Machine learning models and AI-powered APIs enhance automation, personalization, and intelligent decision-making.

8. Chatbots

Natural language processing (known as NLP) and AI-driven chatbots provide real-time support and customer assistance within web apps.

9. Smart data

Advanced analytics, AI-driven insights, and predictive modelling help web apps process and utilize data intelligently.

10. IoT integration

Web apps can connect with IoT devices via WebSockets and APIs to monitor, control, and analyze real-world data.

Of course, the more advanced features you add, the higher the cost of the app’s development. When deciding your budget, be sure to keep track of your overall costs.

How much does it cost to develop an HTML5 web app?

Development costs of HTML5 apps vary. Below are the average estimates, as well as a few other things to keep in mind:

• Simple app development price tag – $16,000 – $32,000
