How Long Does It Take to Develop an App?

App development is rarely linear. Every product is different, and several factors influence how a web or mobile app is planned and delivered.

If you’re planning to build an app, one of the first things you’ll want to understand is how quickly you can go from idea to a working product.

With clear scope and a structured delivery approach, early versions of a web or mobile app can often reach market in a matter of weeks.

From there, timelines naturally scale with complexity, including integrations, multiple platforms, and the depth of functionality being built.

At Appetiser, we’ve built our delivery approach around this, focusing on getting usable products into market early, then iterating based on real user feedback rather than long upfront build cycles.

Before diving into the development process, it’s worth understanding the biggest variable that affects any project timeline: app complexity.

Once we’ve covered that, I’ll walk you through each stage of building a web or mobile app.

First things first: how complex is your app?

App complexity plays a major role in how a product is designed, built, and delivered.

Simpler products with well-defined scope can move through design and development quickly, while more complex builds require additional engineering, planning, and validation.

It also depends on how different parts of the system interact, how edge cases are handled, and how thoroughly the product is tested before release.

To make this easier to understand, apps are typically grouped by complexity when scoping work:

Basic App	Simple App	Complex App
Has basic or common interface Develops for one platform Has MVP features	Has custom user interface Develops for one platform Has advanced Features	Feature-heavy user interface Develops for multiple platforms Has a novel feature/s Requires API or integration with third-party applications Has sophisticated data models Requires a new technology

Now that we’ve established what (generally) basic, simple, and complex apps look like, let’s take a look at the app development stages and the average time for each.

How Long Does It Take to Develop an App? Let’s Look at Every Stage

#1 Planning Stage

Developing a successful app starts with clarity: understanding what you’re building, who it’s for, and what problem it solves.

Strong planning is what enables faster, more efficient delivery later in the process. When the direction is clear, teams can move quickly from concept into design and development without unnecessary iteration.

Before a full build begins, it’s crucial to validate the opportunity and define the core product direction within a short discovery phase. At Appetiser, this is typically structured over 2-3 weeks.

Without this foundation, teams risk misalignment, shifting requirements, and avoidable rework during development.

App developers likely need to change app designs multiple times before they finalize the specifications to create apps that satisfy user expectations.

“When the client is unsure of his desired output and wants to change every now and then, and we’ve got the wrong estimation of the timeline of the projects, those are the biggest challenges we usually encounter. When we encounter this type of issue, we usually just communicate with our team and the client to get a better understanding of what we really want to achieve.”

One of our product managers, Tovah Otton, also has tips to help you better navigate the planning stage of your app development journey:

• Define why you are making the app — what problem does it intend to solve?
• Identify target audiences and their usage habits to get an idea of desired app functionality.
• Conduct market research to understand the current app landscape.
• Research possible competitive app offerings to design a desirable app with unique features or better in-app performance.
• Figure out the most essential features of your app — this will be your minimum viable product (MVP).

#2 Design Stage

The design stage is where the product starts to come to life. Ideas turn into clear user interfaces, flows, and working prototypes.

It’s a key step in making sure the experience feels intuitive, the structure makes sense, and the product is ready to move confidently into development.

The length of this phase depends on scope and complexity, but with our structured approach and Appetiser Baseplate™, design and prototyping work is typically completed in 2 to 3 weeks for well-defined products.

Our design process usually flows through:

• Sketching
• Wireframing
• Visual design and branding
• Interactive prototyping

It’s a tight, focused process that gets you from concept to something real you can actually test.

 

#3 Development Stage

This stage is where the actual app coding happens.

App development isn’t a single long phase. It’s a sequence of decisions, builds, and adjustments that turn a scoped idea into a working web, iOS, or Android app.

The biggest difference in speed usually comes down to how early you can start building something real.

When the MVP is clearly defined, teams don’t waste time on uncertainty. They start with core functionality, get something working early, and build on top of that in structured iterations.

At Appetiser, we treat the MVP as the foundation of speed. Once that’s locked in, the focus shifts to continuous delivery. Small, meaningful builds are shipped regularly rather than large, delayed releases.

It’s how we keep feedback moving through the build so decisions are made with real context, not assumptions.

Testing happens alongside development, not after it, so issues are caught early and don’t compound later in the build.

The result is a build process that stays moving. Less time waiting for “big milestones,” more time shipping real progress.

Through this data-led approach, our app development company has helped numerous partners attain speed to market, achieve a significant return on app investment, and gain a competitive advantage.

Take, for example, Dimers.

In under four months, we helped the Aussie-born sports prediction startup launch its web app and make a global impact. Dimers has managed to generate thousands of users, secure $5 million in funding, and penetrate the illustrious US market.

#4 Launch

Launching an app isn’t as simple as clicking a few buttons, particularly if you’ve developed a native application.

Before publishing your product in the app stores, your Android or iOS app has to go through review processes.

The Apple App Store reviews 90% of the iOS apps submitted to the platform in less than 24 hours. If your app meets its respective guidelines, you can expect it to be deployed near that timeframe.

Meanwhile, Android app deployment on the Google Play Store usually takes 2 to 7 days, depending on app complexity and other factors. The review process may even take longer in exceptional cases.

Launch faster, build smarter

App development follows a structured process that adapts to the scope, clarity, and decisions made throughout the build.

When the direction is clear early, teams can move quickly from planning into development and maintain momentum through to launch.

As the product evolves, changes and refinements naturally happen. The key is having a system in place that keeps things moving forward as decisions evolve.

Over years of building hundreds of digital products, Appetiser has developed a delivery system designed to get ideas to market faster. Fewer handover gaps between stages and clearer progress throughout the build.
