The glossary every non-technical founder needs

You’ll probably hear the term MVP a lot when starting an app project.

A common misconception is that an MVP means building a “basic” or incomplete version of an app… it doesn’t. An MVP is the first version of your product that includes enough functionality to solve the core problem for your users and allow you to learn from real feedback.

The goal isn’t to build everything at once. It’s to identify the most valuable version of your idea, get it into users’ hands, and use what you learn to make smarter decisions about what comes next.

For example, imagine you’re creating a travel app. Your long-term vision might include personalised recommendations, booking functionality, loyalty features, AI-powered suggestions and social sharing. An MVP might focus on the one thing that makes your product valuable: helping users discover and save places they want to visit.

By starting with the right foundations, you avoid spending time and budget building features before you know whether they’re actually valuable.

This approach is becoming increasingly important. Research found that one of the biggest reasons startups fail is building something the market doesn’t need, with 35% of failed startups citing a lack of market need as a reason for failure.

An MVP helps reduce that risk by putting learning at the centre of development.

UX is one of those terms that gets used frequently, but it’s often misunderstood. User experience is about how someone feels when they use your app. It covers everything from how easily they can complete a task to whether the journey feels intuitive and enjoyable. A good UX means users don’t have to think too hard about what to do next.

Think about the apps you use every day, the best ones usually feel simple. You can find what you need quickly, complete actions naturally, and move through the experience without friction. That simplicity doesn’t happen by accident.

Behind every smooth experience is research, testing, design decisions and a deep understanding of user behaviour. A great app isn’t just one that works technically, it’s one that works for the person using it.

If UX is about how an experience works, UI is about how it looks and feels. UI covers the visual elements of your app: colours, typography, buttons, layouts, icons and animations.

But good UI isn’t just about making something look attractive. A beautifully designed app that’s difficult to navigate won’t create a great experience. The visual design needs to support the user journey and make interactions feel natural. Think of UX as the structure of a house and UI as the interior design. Both need to work together to create something people want to spend time in.

Front-end development is the part of an app that users interact with directly. Everything you see on your phone screen (the buttons you tap, the pages you scroll through, the forms you complete) is powered by front-end development.

Developers take designs created by the UX/UI team and turn them into a working product. For mobile apps, this could involve technologies such as React Native, Swift or Kotlin, depending on the approach being taken.

The important thing to understand is that front-end development isn’t just “making the design work”. Developers also think about performance, accessibility, responsiveness and making sure the experience feels smooth.

If the front end is everything users see, the back end is everything happening behind the scenes. The back end manages things like:

• storing information
• processing requests
• handling user accounts
• connecting different systems together
• managing security

For example, when you open a food delivery app and see your previous orders, the front end displays that information, but the back end is responsible for storing and retrieving it. The back end is the engine that keeps your app running.

API is one of the terms that sounds much more complicated than it actually is. An API is essentially a way for different systems to communicate with each other. Think of it like a waiter in a restaurant - you (the app) place an order and the waiter (the API) takes that request to the kitchen (another system), collects the information, and brings it back to you.

APIs allow apps to connect with external services without needing to build everything from scratch. For example, a travel app might use APIs to connect with:

• payment providers
• maps
• booking systems
• weather services
• customer databases

They’re a huge part of building modern digital products because they allow businesses to create richer experiences more efficiently.

A database is where your app stores and manages information. This could include:

• user profiles
• preferences
• transactions
• messages
• bookings
• content

Whenever you use an app and your information appears exactly where you expect it to, there’s likely a database working behind the scenes. Choosing the right database structure early is important because it affects how scalable and reliable your app will be as it grows.

A framework is a set of tools and structures that developers use to build software more efficiently. Rather than starting completely from scratch, developers can use frameworks that provide established patterns and solutions.

For example, React Native is a framework used to build mobile apps across different platforms while sharing much of the same codebase.

The choice of framework depends on your product goals, technical requirements and future plans. There isn’t one “best” option, but there is an option that best fits your needs.

When building a mobile app, you’ll often hear discussions around native and cross-platform development. A native app is built specifically for one operating system. For example:

• iOS apps are built using technologies designed for Apple devices
• Android apps are built using technologies designed for Android devices

A cross-platform app uses technology that allows developers to build for multiple platforms from a shared codebase. The right choice depends on factors such as:

• your users
• performance requirements
• budget
• timeline
• future plans

It’s not about choosing the “better” option, you need to choose the approach that supports your product.

Technical debt is one of the most important concepts for product owners to understand. It describes the future cost created when quick technical decisions are made today.

Just like financial debt, technical debt isn’t always bad. Sometimes moving quickly is the right decision. The challenge comes when shortcuts continue building up without being addressed.

For example, rushing a feature out without considering scalability might help you launch faster, but it could create problems when you need to expand later. Good development teams balance speed with long-term thinking.

Testing is how teams make sure an app works as expected. Quality Assurance (QA) involves checking everything from basic functionality to edge cases. A QA tester might check:

• Does the login work?
• Does the app behave correctly without internet?
• Does it work across different devices?
• Are there any unexpected errors?

Testing happens throughout the development process, helping teams spot issues early, improve reliability and make sure the final product delivers the experience users expect.

Analytics help you understand what’s happening inside your app. They answer questions like:

• Which features are users engaging with?
• Where are people dropping off?
• How often are users returning?
• What behaviours are driving success?

Without analytics, you’re making product decisions based on assumptions. With analytics, you can use real user behaviour to guide improvements.

Cloud hosting is where your app’s data and services live. Instead of running everything from physical servers owned by your business, cloud platforms allow applications to use flexible infrastructure managed remotely.

Services like AWS, Microsoft Azure and Google Cloud help businesses build apps that can scale as demand changes. This matters because the infrastructure needed for 1,000 users is very different from what’s needed for 1 million.

Agile is a way of managing software projects that focuses on collaboration, flexibility and continuous improvement. Rather than planning every single detail months in advance and only reviewing the final product, Agile teams work in smaller cycles.

This means you can:

• review progress regularly
• test ideas earlier
• adapt based on feedback
• make informed decisions as you go

For digital products, this flexibility is incredibly valuable because user needs and market expectations can change quickly.

The best product owners aren’t the ones who know every programming language or understand every technical term. They’re the ones who ask great questions, understand their users and work with people who can turn ideas into reality.

Technology should enable your vision, not become a barrier to it.

A good development partner will never make you feel like you’re behind because you don’t understand the terminology. They’ll help bridge the gap between your idea and the technical decisions needed to bring it to life.

Because ultimately, building an app is a collaboration. Your knowledge of your customers and industry combined with technical expertise is what creates something genuinely valuable.

Building a digital product doesn’t have to feel overwhelming. Whether you have an idea you want to explore or an existing app that needs improving, our team can help you understand what’s possible and how to get there.
