How Long Does It Take to Launch an App?

When deciding to develop a mobile application, your firm should consider a variety of factors. The point is that you must comprehend the app development process in order to predict its timing. Every firm wants to know when they will be able to debut their mobile application on the market, therefore careful and comprehensive preparation is necessary. As a result, a response to the question “how long does it take to build an app” is necessary. You will be able to determine how long does app development takes if you set expectations for app features and overall complexity.

Understanding the whole process aids in estimating the approximate schedule for mobile app development. It encompasses the interconnected stages that every application goes through. Let’s take a look at those stages and describe what happens throughout each one.


The team sets the requirements and organizes the app development process at this stage. The business analysts assist in distinguishing between must-have and nice-to-have features, give counsel and record everything about the future app beginning with the back-end architecture and finishing with wireframing of the key interfaces. All of this is done to ensure that the final solution corresponds to the business objectives.

The major goal at this stage is to develop project documentation (such as a Specification Requirements Document) in which all of the application’s functionality is specified and explained in depth. It also contains screen mock-ups and user stories that describe the rationale behind everything, how users will interact with the program and its UI parts, and so on.

It is a foundational stage that, for obvious reasons, cannot be merged with any other. Planning necessitates particular consideration for both the client and the development team. This stage is critical to the overall project’s success since it helps to create realistic budget and development timeline goals. The plan often contains sprints (important milestones in the software development life cycle), each of which lasts 2-3 weeks, as well as a description of the deliverables that should be generated within those development sprints.

Business analysis will take around two weeks, during which time business analysts, developers, and even the project manager will interact with clients to find the best solutions. Everything begins with establishing expectations and determining how to put them into action. This stage is mostly concerned with determining the set of functionalities that will be offered to consumers at launch. For example, if this is a food delivery app, the main features will include a product catalog, the ability to place an order, input the delivery address, pay for it, and track the transaction. Extra functionality may include daily discounts, online coupons, and so forth.


The major focus is on the design, with stages completed independently because the UI design can only be produced once the UX design is completed. As a result, the answer to the question “how long does it take to develop an app?” will be determined by the steps listed below.

2–3 Weeks for UX Design

UX designers establish how the user interface will function, which screens and buttons to include, as long as the user experience is governed by straightforward app navigation.

It is a good idea, for example, to provide a section where the client may modify the number of meals selected before adding products to the basket. Yes, you may include a field for the number of servings on the checkout page. However, your first-time users will be unaware of this, which may be quite aggravating, and the client may exit the program before even reaching the checkout screen. A good UX design is defined by how users interact with the program and which actions they should take to achieve certain goals.

3–4 Weeks for UI Design

While UX designers concentrate on how the app works for the clients, UI designers focus on how it appears to them. The UI design stage lasts 3-4 weeks, during which time the designers develop an amazing and appealing interface for your application. Creating the buttons and sliders is not the end of the process. In the hotel industry, presentation is important. In the case of the food delivery business, the UI designer will also be in charge of developing a set of rules or brand guidelines that should be adhered to the portrayal of the goods in the catalog. This is essential to ensure that the application’s architecture is flexible enough and that there will be no problems.


We’ve arrived at the question of “how long does it take to code an app?” The good news is that the team generally works in tandem on the back-end, front-end development, and testing to reduce the time it takes to build a mobile app.

6–8 Weeks for Back-End Development

Back-end development takes 6-8 weeks to complete since it involves working with the app server and the database. All data for such service applications are kept on the back-end server.

6–8 Weeks for Front-End Development

Once the server is under construction and the database structure is complete, the development team may begin parallel work on the product’s front-end or the mobile application itself. It will render and organize data from the previously stated back-end server.

From 6 to 8 weeks, front-end developers typically oversee the activities that allow functionality. Native frameworks such as Swift, Objective – C, and Java are used by developers to generate different versions for the App Store and Google Play.

2 Weeks for Testing

The majority of the testing stage occurs concurrently with active development, as developers’ complete features and immediately transmit the code to the QA team. What is crucial in the context of this post is that the app’s final version has all of the modules connected and should operate together. For the following 1-2 weeks, the app’s release version will be tested, and engineers will work on any issues discovered by the testers. Even at the last stages of testing, the development team should be prepared to work as hard as they did throughout the active development period. At this point, the roles of testers and developers are reversed, with the tables turning to have testers sending code to the developers instead of developers sending code to testers.


The final preparation stage is critical for finalizing the details, fixing any remaining issues, and publishing the program to the App Store and Google Play. The publication procedure itself is a complicated one that might take some time. Even trustworthy firms frequently fail to pass the App Store and Google Play moderation for a variety of reasons including simple moderation errors. Given the volume of fresh requests received by the retailers daily, this procedure might take days or even weeks to complete.


The development team must monitor the performance for around two weeks to ensure that it functions correctly and meets all established standards. Careful maintenance is extremely beneficial to the general functioning of the app in the future. The development team should be prepared for huge quantities of work during this phase and should essentially be in the same line-up as during the active development stage to be ready for any urgent repairs or modifications.


If we’re talking about anything extremely easy, it’ll take 16 weeks (4 months) or a little longer. Time Buddy for time zone synchronization and basic notes and reminders apps like Wunderlist are two decent examples.

Medium-complexity applications, such as collaborative tools like Asana or an eCommerce shop with advanced capabilities like a 3D display of the products, will most certainly take 24 weeks or more to create.

Complex and complex apps will require 40+ weeks of development time, depending on the scope of the project and the business’s objectives. Such applications often include a couple of “killer features,” such as AI components, AR, machine learning, a novel UI, and so on, or all of them at once. Some of the examples include Google Drive, Uber, and Telegram among a sea of others.
