How long will it take to develop a mobile application in 2025?

At NetDevices, we are often asked how long it takes to develop a mobile application. Although the time frame can vary, it is essential to understand the key elements involved.

In this article, we will analyze the factors that impact application development time and provide you with a realistic estimate of the timeframes to anticipate.

Factors that determine development time

Before estimating the time required to create a mobile application, it is important to identify the main factors that influence this timeframe. These criteria are essential for establishing a realistic and structured project schedule.

The level of complexity of the project

The chosen platform (iOS, Android, or hybrid solution)

The choice of platform has a significant impact on the schedule. Whether you decide to develop for iOS, Android, or via a hybrid solution, the timeframes may vary:

• iOS involves the use of Swift or Objective-C.
• Android favors Java or Kotlin.
• Cross-platform frameworks such as React Native or Flutter allow you to develop a single code base for both platforms, which significantly reduces development time.

At NetDevices, we generally favor hybrid or cross-platform technologies, as they offer an excellent compromise between speed of implementation, controlled costs, and quality.

The skills of the development team

The developers' experience is also a key factor. An experienced team is better equipped to handle technical challenges, allowing them to move forward more quickly and efficiently. On the other hand, a novice team will take longer to manage difficulties and integrate certain features. That said, junior profiles quickly develop their skills, especially when they are trained in modern methods and the latest technologies. If you outsource your project, be sure to entrust the development to qualified professionals.

The main phases of development and their estimated duration

The process of creating a mobile application involves several well-defined stages. Each phase plays a crucial role and requires a specific amount of time.

1. Planning phase and needs analysis

Duration: 2 to 4 weeks

This is the preparatory phase, where everything begins. It is crucial because it determines the vision for the project and the direction to take.
What we do at this stage:

• Define the objectives of the application (e.g., sell products, improve customer loyalty, etc.).
• Identify target users (e.g., students, athletes, professionals, etc.)
• Study the competition: what do other similar apps offer?
• Write functional specifications, a detailed document that will serve as a guide for the entire team.

2. UI/UX design

The user experience and graphical interface are crucial for the adoption of the app. This phase includes:

• The creation of functional models (wireframes)
• The creation of visual prototypes
• The structure of navigation
• Screen validation by the client

Estimated duration: between 3 and 6 weeks

3. Backend development

The backend is the invisible but central part of the application. It enables:

• Manage business logic
• Store and secure data
• Interact with the frontend via APIs

Estimated duration: between 4 and 8 weeks

4. Frontend development

This step concerns the part visible to the user. It includes:

• Design integration
• Coding features on the client side
• Performance optimization

Estimated duration: between 6 and 12 weeks

5. Tests and corrections

This phase ensures that the application is functioning properly. It involves:

• Unit and integration tests
• Performance tests
• Correction of identified bugs

Estimated duration: between 2 and 4 weeks

6. Deployment and publication

Before launch, certain tasks are necessary:

• Finalization of the code
• Preparation of visuals and descriptions for stores
• Submission to Apple and Google platforms

Estimated duration: between 1 and 2 weeks

These times are indicative and may vary depending on the nature of the project.
If we add up all the stages, from planning to deployment, we can better understand how long it takes to develop a mobile application, taking into account each essential phase.

In summary, how long does it take to develop a mobile application?

In general, it takes between 3 and 6 months to develop a complete mobile application, from the initial idea to its launch. This timeframe can be explained by:

• A balance between speed and quality
• The possibility of making several iterations based on feedback
• The application of high-quality technical and UX standards
• The flexibility needed to handle the unexpected

Delays vary depending on the type of application.

• Simple apps (3-4 months): e.g., task app or basic game
• Moderately complex apps (4-6 months): e.g., marketplace, social network
• Complex apps (6+ months): e.g., augmented reality tools or complex business systems

Use the MVP method to move faster

What is an MVP and why use it?

An MVP, or Minimum Viable Product, is the simplest and most functional version of an application. It contains only the essential features needed to meet the main needs of users.

The goal of the MVP is to quickly launch the application on the market in order to:

• Test the concept with real users
• Validate assumptions (is the app appealing? Does it solve a real problem?)
• Gather feedback to improve it over time

We are talking about a usable product, but not a final one. It is deliberately simplified, with no secondary features.

Its advantages:

• Rapid market launch
• Reduced development costs
• Real-world testing with early adopters
• Better responsiveness to feedback

How does MVP influence development timelines?

Adopting an MVP significantly reduces the time needed to launch an application. Here's why:

Postman	Impact on deadlines
Fewer features	Development time is reduced by 30 to 50%.
Lighter testing process	Fewer cases to check, so faster testing
Fewer screens, fewer integrations	Faster development and design
Early launch	Possibility of publishing a first version in 2 to 3 months
Quick user feedback	We avoid coding unnecessary features.

Result: a first version can be put online in 2 to 3 months.

Let's imagine a meal delivery app.
Full version: geolocation, online payment, order history, rating system, referral program, chat with the delivery person, etc.
MVP: only meal ordering, with payment upon delivery.

Result:

• MVP ready in 2 to 3 months
• Full version available later, with improvement cycles of 2 to 4 weeks for each new version

Why do large projects take longer?

More complexity, more integrations

• Advanced technical features (AI, big data, etc.)
• Connection to external systems
• High safety requirements
• Large-scale performance to be guaranteed

Larger teams to manage

• More complex coordination
• Synchronization of different teams
• Slower code review
• Onboarding time for new members

These projects can therefore last between 9 and 12 months, or even longer. To limit delays, agile approaches and modular structuring are often implemented.

Common causes of delays in developing a mobile application

Delays caused by the customer

1. Frequent changes in requirements
2. Late decisions
3. Missing elements (content, access, API, etc.)
4. Not enough time or resources for user testing

Delays on the provider side

1. Incorrect estimation of complexity
2. Unexpected technical issues
3. Departures of key members
4. Poor internal organization

Delays caused by third parties

1. Late update of third-party SDKs
2. Changes to App Store or Google Play rules
3. Cloud service interruptions
4. Awaiting certifications (particularly in regulated sectors)

In summary, how long does it take to develop a mobile app? For a well-structured app, allow between 3 and 6 months. But if you opt for an MVP, you could reduce this time to just 2 or 3 months.
