How we develop mobile products

Here are the steps we go through together:

1. Discovery: Setting the stage

Every great app starts with a solid plan β€” and this is where we build it. During discovery, we take a deep dive into your business model, your users’ expectations, and your technical landscape. The goal? To make sure we’re building something that fits you β€” not just a good-looking interface, but a product that actually delivers. We take time to understand your goals, outline the core functionality, and flag any risks that might pop up later. Together, we shape a clear, realistic roadmap with aligned expectations and zero guesswork. Feature prioritization, competitor analysis, and scalability planning are all baked in from the start. We’re not just setting the stage for a successful launchβ€”we’re laying the foundation for long-term growth.

2. Design: Making it feel right

With 50+ mobile interfaces designed, we’ve seen what works β€” and what doesn’t. Great design isn’t just about how things look; it’s about how everything feels in the user’s hands. That means smooth navigation, intuitive gestures, and interactions that just flow β€” whether you're using one hand on a small screen or multitasking on a tablet. We stick to Apple’s Human Interface Guidelines and Google’s Material Design standards to make sure the app feels completely native, no matter the platform. That includes everything from tap zones and spacing to typography and animation timing. We refine every pixel to boost usability, accessibility, and user satisfaction.

3. Development: Building the app

We choose the right tech for the job. Most often, that means React Native β€” an efficient and cost-effective way to build apps that run seamlessly on both iOS and Android with a single codebase. It’s perfect for MVPs, growing products, and small businesses looking to move fast without compromising on quality. Our development process follows Agile principles, so you stay in the loop with frequent updates, real-time collaboration, and room to adapt as we go. You directly influence priorities while we handle the heavy lifting β€” from architecture to integrations. Everything is built with platform compliance in mind. From day one, we align with App Store and Google Play requirements to reduce the risk of rejections or rework.

4. Testing: Making sure it works

Before your app ever reaches users, we make sure it’s solid. That means putting it through rigorous manual and automated testing to surface bugs, eliminate security risks, and fine-tune performance. We test across devices, screen sizes, operating systems, and user scenarios. From everyday usage to high-traffic simulations and edge-case workflows, we aim to catch anything that could go wrong β€” before your users do. Usability? Checked. Performance? Stress-tested. Security? Locked in. This level of thoroughness isn’t just nice to have β€” it’s why we maintain a 99.89% work acceptance rate. When it’s time to launch, you can do it with confidence, knowing your app has already passed our toughest tests.

5. Deployment: Launching with confidence

A seamless launch doesn’t happen by accident. We take care of the whole submission process for both the App Store and Google Play, making sure every box is checked, every requirement met, and every technical detail covered. That includes everything from preparing assets and metadata to managing back-and-forth communication with the review teams. Our goal is to reduce approval timelines and eliminate the risk of rejection due to overlooked issues or compliance gaps. You don’t have to chase down guidelines or guess what went wrong. We’ve got it handled β€” so you can go live with zero stress and start reaching your users right away.

6. Growth: Helping it keep up

Getting your app to market is just the start. We stay involved post-launch to help you keep the momentum going. That includes monitoring real-world performance, analyzing user behavior, and making smart updates based on real feedback β€” not just assumptions. Need to scale your infrastructure? Improve app store ratings? Launch new features? We’ve got your back. Whether it’s tuning the user experience, enhancing performance, or adjusting to new business goals, we evolve your app to meet the moment β€” and the future. Your app won’t just stay functional. It’ll keep getting better.

Clearing up your concerns

Can I extend my web app to mobile?

If your web app already runs smoothly, we can bring it to mobile without starting from scratch. Depending on what you're aiming for, we can:
– Turn it into a PWA for mobile-friendly access
– Use React Native for a cross-platform experience
– Go fully native for top-tier performance and deep OS features
We’ll help you figure out the best path forwardβ€”one that fits your goals, your budget, and how you plan to grow.

What tech stack do you use for mobile app development?

We don’t push a one-size-fits-all stack. Instead, we match the tech to your product and business needs.

Need a cross-platform app that runs well and cuts dev time? We go with React Native. Going native? We’ll use Kotlin for Android.

Behind the scenes, we also make sure everything connects: backend services, real-time data, APIsβ€”you name it. Before coding starts, we dig into your product vision, audience, and plans to build a scalable and solid foundation.

Should I build a native, cross-platform, or PWA app?

That depends on what matters most to you:
– Native: Best for performance and deep device integration
– Cross-platform: A smart way to save costs while covering both iOS and Android
– PWA: Lightweight and fast to launch, especially if app stores aren’t a priority
We’ll shape the approach around what you’re trying to achieveβ€”no fluff, just what fits your users and your goals.

Will you help publish my app on the App Store & Google Play?

Yes β€” we handle the entire publishing process, from requirements to rollout. That includes compliance checks, asset prep, and beta testing support.

Since Apple and Google change policies often, we bake their requirements into development early on. This helps your app get approved faster and avoids frustrating delays.

Can my mobile app work offline?

Absolutely. We can build your app to run even when there’s no internet. We use tools like local caching, background sync, and progressive data loading to keep the experience smooth.

Once the device reconnects, the app syncs automatically β€” no extra work from the user’s side. Whether you need basic offline access or full functionality, we’ll tailor the setup to fit your business.

How do you keep us in control throughout the process?

You’re always in the loop. We provide real-time access to project boards, code, and progress updates. You’ll see regular sprint demos and have direct contact with our engineers.

If your priorities change, we adjust together. No surprises, no silos β€” just clear communication and full visibility.

Will you help us retain expertise over the outsourced parts?

Yes, and it starts from day one. We document everything β€” architecture, workflows, technical decisions β€” so nothing is lost.

Your team can access code, API docs, and pull request threads in real time. If you want to take over later, we’ll support your internal devs with smooth onboarding and knowledge transfer.

How can we be sure you’ll deliver exactly what’s agreed on?

We lock in the requirements early β€” wireframes, features, and all β€” so there’s no confusion later.

Our Agile process keeps you involved and allows room to adjust. You’ll see each milestone as it’s hit, and we stay in sync to ensure you get exactly what was plannedβ€”no misalignment, no guesswork.

Will the same team work on our product for consistency?

Yes. We value long-term project continuity. Our devs stick around β€” our team’s average tenure is 3.8 years, and turnover was just 5.5% last year (way below industry norms).

If anyone new joins your project, we’ve got a clear onboarding process to keep things seamless.

How can we understand outsourced code for maintenance?

We make our code easy to follow. You’ll get full access to everything β€” repos, docs, comments β€” so your team always knows what’s going on.

Need extra clarity? We offer live walkthroughs and Q&A sessions to help your internal devs feel fully in control.

Will language barriers affect communication?

No worries here. We work with international teams daily β€” 98% of our clients are from the US and UK β€” so we’re used to clear, fluent communication.

We agree on tools, timelines, and update rhythms from the start, so you always know what’s happening and when.

Will we retain full IP ownership of the product?

Yes, 100%. You own everything β€” source code, architecture, deliverables.

No licenses, no restrictions, no fine print. The product is yours to update, scale, and manage however you want.

How can you ensure stability, given the events in Ukraine?

We’ve stayed fully operational throughout even the toughest times. Our team is distributed across Ukraine and Europe, with infrastructure designed to avoid disruptions.

Since 2022, we’ve kept projects moving, hit every delivery, and grown our team. No matter what’s happening around us, we make sure your development stays stable and on track.

How do you keep estimates accurate and our budget on track?

Once we start, we track progress using the Cost Performance Index (CPI) to keep variances under 10%.

You’ll get regular budget updates with clear comparisons between estimates and actuals. And if anything changes, we talk firstβ€”no surprise charges, no vague invoices.
