Mobile app development phases: This is how we work

At Rootstack, we understand that for you, as a leader or executive in your company, developing a mobile application is not just a technological project — it is a strategic investment. That’s why clearly describing the phases of mobile application development is essential for giving you a transparent view of the process, helping you understand how difficult it is to create an app and how long it might take, and building your confidence in us as your technology partner.

1. Discovery and Planning

The first stage, often underestimated, is the heart of the project’s success. Over several weeks (typically 2 to 4 weeks), we work with you to define your app’s vision, business objectives, target audience, and realistic project scope. This phase minimizes risks and prevents costly changes later on.

According to recent studies, a solid discovery process can save significant resources compared to fixing issues after launch.

We also define the ideal mobile application strategy for your business: whether starting with an MVP is appropriate, which platforms to prioritize (iOS, Android, or both), whether a native or cross-platform approach is better, and which technologies best support your goals.

2. UX/UI Design

Once we have strategic clarity, we move on to user experience (UX) and user interface (UI) design. This stage typically lasts between 3 and 6 weeks, depending on the project’s complexity.

In this phase, we create wireframes, interactive prototypes, and high-fidelity mockups. We test the designs with real users to ensure smooth, intuitive navigation aligned with your brand. The goal is for your application to be useful, visually appealing, and highly functional.

According to global studies, a strong design phase increases the chances of user adoption and reduces friction during development.

3. Technical Architecture and Development

At Rootstack, we build a strong technological foundation from the start. We define scalable architectures, efficient backend systems, required integrations, security models, and the entire frontend experience. These decisions affect performance, download size, battery usage, and long-term scalability.

The development phase, based on recent data, can take between 8 and 20 weeks depending on the type of application. We work modularly, using agile methodologies that allow for frequent deliveries and continuous review. Our team develops:

Frontend: all interfaces, animations, and navigation using native or cross-platform technologies.
Backend: APIs, databases, business logic, authentication, security.
Integrations: payments, analytics, third-party services, notifications, maps, AI, and more.

4. Quality Assurance (QA) and Testing

A solid application requires an exhaustive testing process. At Rootstack, we conduct functional, performance, security, compatibility, and usability testing. This phase can take between 2 and 6 weeks depending on the project scope.

Academic studies show that many mobile apps fail due to insufficient testing, which directly affects user retention. We apply both manual and automated tests, as well as CI/CD pipelines to ensure every version is stable and secure.

5. Preparation and Launch

With the application fully validated, we prepare it for launch on the Apple App Store and Google Play. This includes creating descriptions, screenshots, icons, metadata, and meeting each store’s requirements.

The review process can take anywhere from a few days to several weeks, depending on the type of app. We also configure analytics, monitoring, and post-launch strategies to ensure your application begins delivering impact from day one.

6. Maintenance and Continuous Improvement

Launching is not the end — it is the beginning of the growth cycle. Every application needs maintenance, continuous optimization, new features, and regular updates. At Rootstack, we build products that scale both technically and functionally.

We monitor key metrics such as retention, conversions, load speed, stability, and user satisfaction to propose ongoing improvements.

How difficult is it to create an app, and how long does it take?

These are common questions for any executive evaluating a technology investment. The difficulty depends on scope, features, integrations, and technology.

• Simple apps: 2 to 4 months.
• Medium complexity apps: 4 to 9 months.
• Enterprise-level apps: 6 months to over a year.

At Rootstack, we optimize timelines thanks to our experience, specialized teams, and agile processes.
