Our mobile application development services:
With NERDZ LAB, if you are looking to build, say, an app for iPhone, you don’t have to hire an iOS app development company to write code, a designer to craft an attractive UI/UX, a testing team to ensure quality, and a project manager to fine-tune all the processes and set them in motion. We cover everything. Below are our core services.
Custom software development
We build mobile solutions from scratch based on your goals, user needs, and competitor analysis. Then we design a product that meets your business objectives, attracts your target audience, and stands out in the market.
Native iOS and Android app development
Want a scalable, high-quality native iOS or Android app? We’ve got you covered. Using Apple and Android standards, plus Swift and Kotlin, we build reliable, scalable products with smooth long-term performance.
Application management services
Already have an app that needs to stay reliable and competitive as technology evolves? A dedicated development team is your best choice. Our ongoing app management services keep your product up to date and ready to grow.
Application testing services
We assign a testing manager (or a QA team) to ensure your mobile app is bug-free and runs smoothly. Through fast, scalable manual tests on multiple devices, we check performance, UI/UX, compliance, and other key aspects, making sure we find issues before your users do.
Discovery phase services
Navigate your project's potential with our discovery phase services. In just a few weeks, we will analyze, strategize, and outline your project's roadmap. Uncover opportunities, mitigate risks, and set a clear direction for your development journey.

AI development services
Even if artificial intelligence is a hot topic, success takes hard work and know-how. Let us explain the technology and what it can do for your business, then build the solution you need. We’ll share our expertise every step of the way to protect your investment and set you up for success.

Successful mobile products are built on more than clean code — they require a deep understanding of how real users interact with their devices every day. At NERDZ LAB, we build apps that feel natural across platforms and scale effortlessly as your user base grows. We provide the strategic leadership and technical execution needed to navigate the complexities of both the App Store and Google Play.
1.
Full-cycle app development
Our team of 80+ experts covers Android & iOS development, front-end and back-end engineering, design, and QA. We can also assign a tech lead or PM to streamline communication and ensure smooth collaboration — handling every stage of custom app development from concept to launch.
2.
Full project ownership
We’re more than seasoned engineers — we’re startup founders who see your product from both technical and business angles. Having faced the same challenges, we treat every project as our own, making your success our priority.
3.
Exceptional communication and customer service
We keep communication clear and transparent — explaining every step, sharing regular updates, and asking questions when needed. This blend of technical expertise, clarity, and commitment to client success is why people stay with us.
Technologies
With an in-depth knowledge of all technologies necessary to build a successful app, we always stay ahead of the game. That’s why we can handle complex technical challenges associated with native application development and offer alternative solutions when a prescribed path is a no go.
From idea to ready-for-market product
01
Discovery and product strategy
We uncover your business goals and target audience needs in the first meetings. This deep dive into your product and market context creates a direct path to a tailored mobile solution.
02
Requirements
We build a solid product strategy through thorough customer and competitor analysis, then finalise all technical requirements and a detailed mobile roadmap to ensure an efficient development process.
03
Mobile UX/UI design
We craft a mobile-first experience — including mind maps, wireframes, and interactive prototypes — prioritising intuitive user journeys and platform-specific guidelines to drive initial user growth.
04
MVP development
We turn requirements into a functional beta version of the app, building core features and integrating them with a secure back-end so you can start testing with early adopters as quickly as possible.
05
Multi-device testing
We run performance checks across dozens of real devices to confirm the app is stable, fast, and secure — and that it’s ready for the official launch.
06
Store submission and continuous support
We manage the full submission process for the App Store and Google Play. Once live, we focus on continuous improvement to help you stay ahead of market changes and scale effectively.

How much does it cost to create an app?
The app’s price must be a balance between the cost to build an app, the quality of code, and the time efficiency of the app development project. Usually, you can’t have three of them at a time. The outsourcing location matters here a lot as well. Learn more about the pricing formulas here.

How long does it take to build a mobile app?
It depends on the complexity and platform. A focused single-platform MVP typically takes 2–4 months. A multi-platform product with custom design, backend integrations, and third-party APIs can take 4–8 months or more.
The clearest way to get an accurate timeline is to go through a Discovery Phase first — it breaks the project into tasks, surfaces dependencies, and gives you a reliable delivery schedule. Send us your project details and we’ll estimate it.
What to choose for my project: Android or iOS app development?
When choosing between Android and iOS app development, consider the two platforms’ pros and cons based on your business needs. Start by pinpointing your budget, time to market, and the audience you want to reach. After defining your target users and app functionality, you will know how to assess each platform’s benefits and drawbacks.
Choose iOS-first app development when:
- You need to build MVP quickly and within a small budget
- You want to generate higher revenue per user
- You’re targeting North America and Oceania markets
- You put data security and privacy first
- You want to develop an e-commerce app
Choose Android-first app development when:
- You’re targeting the global market or emerging markets in Asia, Latin America and Africa
- Your app has unique features that iOS doesn’t support
- You want to reach a tech-savvy audience

Cross-platform vs. native development. What’s your say?
Based on our experience, we can say that cross-platform development is not nearly the same quality as native development. There’s a lack of support from Apple or Google, and graphics look like a website rather than a mobile app. It’s often said that cross-platform development takes half as much time as native apps, but in fact, it’s only 20-30 percent faster. The project estimate might become shorter, but the project timeline gets longer. Unlike native development, when two developers work in parallel and independently, there’s only one developer working on a cross-platform app—and even if there are two or three of them, they won’t be able to work independently anyway.
How does NERDZ LAB ensure the quality of its development?
Our team has helped numerous companies to release products with high-quality code, well-tested usability, and a memorable user experience. We build our software testing services on best industry standards (like ISTQB certification), rely on automated testing as a practical approach within CI/CD paradigm, and work with a broad array of real devices and professional testing tools. On top of that, we thoroughly plan and carefully implement the above-mentioned test activities and tasks in a timely manner. Find out more here.
