Before You Build A Mobile App, You Need To Know About PWAs

Building a mobile app sounds fairly straightforward on paper. You have an idea, define your features, think about user journeys and start imagining what the experience might look like on iOS and Android. Somewhere early in that process, however, a much bigger decision appears: what type of mobile app should you actually build?

For years, businesses generally had two choices. You either built a Native app or went down the Hybrid mobile app route. Today, there is another option getting far more attention: Progressive Web Apps, commonly known as PWAs. While they are not the right solution for every project, they are changing how many startups and established businesses think about mobile development.

Whether you're creating an EdTech platform, building a PropTech experience, a FinTech solution or developing operational software for your internal teams, understanding PWAs early can save a huge amount of time, complexity and potentially unnecessary costs later. Like most technology decisions, there is no universal right answer. But before you commit to a mobile development approach, PWAs deserve a place in the conversation.

Mobile Apps Traditionally Followed Two Main Paths

For many years, businesses wanting to build mobile applications generally had two options available to them: Native or Hybrid development. Both remain highly relevant today and both continue to serve important purposes depending on the requirements of the project.

Native applications are developed specifically for individual operating systems. In practical terms, this usually means building one application for iOS and another for Android using platform-specific technologies. Many of the most feature-rich applications you use every day, such as banking platforms, navigation tools and advanced mobile experiences, have traditionally followed this approach.

There are some clear advantages to Native development. Performance is often excellent, user experiences tend to feel highly polished and developers have deep access to hardware features such as cameras, GPS functionality, Bluetooth and device-specific capabilities. If your application relies heavily on performance or complex hardware interactions, Native development can often be the right choice.

The trade-off, however, is that maintaining separate applications can become more expensive and more resource intensive. Features frequently need to be developed multiple times, testing can become more involved and maintaining different codebases naturally introduces complexity as products evolve.

Hybrid applications emerged as a way to reduce some of this complexity. Rather than building completely separate applications, Hybrid frameworks allow developers to create a shared codebase that works across multiple platforms.

For businesses looking to move faster, Hybrid apps can offer significant advantages. Development timelines can often be shorter, maintenance becomes simpler and costs may be reduced because teams are not duplicating work across platforms.

Of course, there can be trade-offs here too. While modern Hybrid technologies have come a long way, there can still be scenarios where highly advanced functionality or performance requirements favour a Native approach.

The important thing is this: neither option is universally better than the other. It depends entirely on what you are building.

For years, many businesses assumed these were the only realistic choices. Today, however, Progressive Web Apps are creating a third path that sits somewhere between traditional websites and mobile applications.

So What Exactly Is A Progressive Web App?

The easiest way to think about a Progressive Web App is as a web-based application that behaves much more like a traditional mobile app.

Users can install PWAs onto their devices, launch them directly from their home screens and interact with interfaces that feel very similar to mobile app experiences. From a user's perspective, the difference is often far less obvious than people expect.

Under the hood, PWAs use modern web technologies to bridge the gap between websites and mobile applications. Without getting too technical, they combine many of the strengths traditionally associated with both worlds.

This means they can support functionality such as push notifications, responsive interfaces, home screen installation, fast loading experiences and offline functionality in certain scenarios.

One of the biggest differences, however, is that PWAs still maintain a web-based foundation. Rather than existing as completely separate digital experiences, your web and mobile platforms can often become much more connected.

For many businesses, that flexibility becomes extremely attractive.

One Codebase, Multiple Experiences

One of the biggest advantages that often gets overlooked with PWAs is the opportunity to create more connected experiences across your digital ecosystem.

Traditionally, businesses could find themselves maintaining a website, an Android application and an iOS application as entirely separate products. While users may view these as a single brand experience, behind the scenes they can become multiple platforms requiring separate updates, separate testing and separate maintenance efforts.

PWAs can simplify this significantly.

Because they are built on web technologies, businesses can often create experiences that work across desktop, mobile and tablet environments from a more unified foundation. Rather than duplicating effort across several disconnected systems, teams can potentially manage and evolve a more connected platform.

Of course, requirements always matter and some projects will still justify dedicated Native experiences. But for the right applications, reducing duplication can become a major operational advantage.

One Mobile App Challenge Businesses Often Discover Too Late

When businesses think about mobile apps, they naturally focus heavily on launch day. The conversation tends to revolve around features, designs, user experiences and release timelines.

What often gets overlooked is what happens after launch.

Because this is usually where things become interesting.

Features evolve. User feedback starts arriving. Internal teams identify opportunities for improvement. Customers request changes and product roadmaps shift.

Imagine launching an EdTech platform and discovering students are struggling with a part of the user journey. Or perhaps your PropTech platform needs improvements to how leads are captured and distributed. Maybe your internal operational software could save staff hours every week with a relatively small workflow adjustment.

Now imagine preparing an update, packaging a new release, submitting changes and waiting for review processes from the app stores before users can access improvements.

App stores absolutely serve an important purpose and their review processes help maintain standards and security. However, for businesses trying to move quickly, these release cycles can sometimes create friction.

This is one area where PWAs can offer meaningful flexibility.

Because they maintain a web-based foundation, updates and improvements can often be rolled out much more efficiently than businesses typically expect from traditional release cycles. Instead of treating updates as major release events, platforms can evolve much more continuously.

For organisations operating in fast-moving environments, this can become incredibly valuable.

The Hidden Cost Of Maintaining Multiple Platforms

Most businesses budget for development and launch costs. Far fewer think carefully about the long-term cost of maintaining and evolving software over several years.

Every new feature, every interface change, every bug fix and every enhancement introduces effort. When separate platforms exist for iOS, Android and web experiences, those changes can often ripple across multiple environments.

What initially seemed like a straightforward development decision can slowly create operational complexity over time.

This does not automatically make Native or Hybrid approaches the wrong choice. There are many scenarios where they remain absolutely the right answer. But maintenance costs and ongoing effort deserve more attention than they often receive.

Technology decisions should not only solve today's requirements. They should also account for where your business is likely to be two or three years from now.

Where PWAs Can Work Really Well

Like every technology decision, context matters.

PWAs can be incredibly effective for certain types of applications and business models, particularly where flexibility and continuous improvement are important.

EdTech platforms are a strong example because educational content, assessments and learning experiences often evolve continuously. The ability to improve experiences quickly can create real advantages.

PropTech businesses can also benefit significantly. Search experiences, customer engagement journeys and lead management processes often go through ongoing optimisation, which means rapid iteration becomes valuable.

Operational tools used internally by teams are another strong fit. Businesses constantly refine processes as they grow and technology that can adapt alongside changing workflows can significantly improve efficiency and employee experiences.

Of course, requirements always matter. Some applications naturally demand more advanced functionality than others.

The Benefits And Downsides Of PWAs

PWAs bring several compelling benefits to the table. Faster update cycles, simpler maintenance, shared codebases and potentially lower development costs can all become significant advantages depending on the application being built.

For startups, this can create opportunities to launch faster and validate ideas efficiently. For larger businesses, it can reduce complexity and allow teams to evolve platforms more rapidly.

But there are trade-offs too.

While PWA capabilities have improved dramatically, certain advanced hardware integrations and background processing features may still favour Native development. There can also be platform-specific considerations, particularly around iOS functionality, depending on your application's requirements.

This is why we rarely believe in technology trends or blanket recommendations (we’ve worked across Native, Hybrid and PWAs for our clients and each was selected based on their unique requirements and what made the most sense).

PWAs can be incredibly powerful, but they are not automatically the right answer simply because they are newer or more flexible.

Choosing The Right Approach For Your Mobile App

Native apps, Hybrid apps and PWAs all have a place.

If you are still in the planning stages of your mobile app, understanding the trade-offs early can save a huge amount of time and frustration later. Technology decisions made at the beginning of a project often influence scalability, future maintenance, user experiences and long-term costs far more than people realise.

Sometimes Native is absolutely the right answer. Sometimes Hybrid creates the ideal balance between performance and speed. And sometimes a Progressive Web App gives your business the flexibility and agility that becomes a genuine competitive advantage.

The best technology decisions rarely come from following trends. They come from understanding your users, your business goals and where your platform needs to be in the future.
