Mobile applications that are both effective and deliver quantifiable results
From idea to implementation, from MVP to scale.
We create products that get the job done: they convert, engage and grow with your business. No unnecessary features and no technological compromises.
What stage is the project at? Various.
Sometimes it’s all worked out. Sometimes it’s still laid out.
We help put it together into a logical whole – with the user, business and technology in mind.

The SYZYGY team’s work on our mobile application has not only strengthened the brand’s digital presence but has realistically translated into increased user engagement and satisfaction. The business effects cannot be overstated – and this is largely due to the talent and commitment of the team.

How will this help your business?
A mobile app is not (just) technology. It’s one of the key channels of your product – a place where the user makes decisions, returns or disappears. If it works well, you can see it in the numbers. If it doesn’t – it does, too.
We help you design an application that supports your business: shortening paths, increasing retention and speeding up the moment of conversion. Without feature overload, instead with real impact on results.
What you can gain:

What do you gain from the technology side?
We are not building a technological “black box.”
In a well-designed application, technology should not stand in the way – it should support development, integration and provide scalability. We design solutions that are not dependent on a particular framework, team or a single decision from the MVP phase.
We know that code ages, that roadmaps change, that teams rotate. That’s why we focus on an architecture that can be developed, optimized and passed on – without “surprises.”
What you can count on:

It’s never too late to ask the question: why and for whom are we doing this? Even if the application is already working – it’s worth stopping for a moment to see if more features support the strategy or just color the reality.

What we do as part of this service
Developing a mobile app is not just development. It’s a series of decisions – from strategy to UX to code scalability and product maintenance. You can entrust us with the entire process or join us where you realistically need us.
Are you a startup with an idea? Do you have an MVP or a working backend? Are you rebuilding the whole thing?
We will adapt to your context.
- We help you determine the role of the app in your ecosystem (and whether you need it at all).
- Workshops? Yes. But not for the process itself – we want to go beyond the brief together and find the real needs.
- We analyze data, users, the market – to not just “make an app,” but to build a product that works.
- Information architecture and user flow – based on data, not guesswork.
- Interfaces designed for retention, accessibility and real-world use.
- Design System that organizes, accelerates and facilitates development – now and later.
- Flutter or native technologies – stack to suit your needs, not your preferences.
- We integrate with backend, CMS, loyalty systems, payments, login.
- We care about code quality, performance, security – and that everything can be maintained, developed and passed on.
- We test manually and automatically, on various devices, systems and cases.
- We prepare the release – screenshots, copy, descriptions for the App Store and Google Play.
- We help with rollouts – including staged and segmented rollouts.
- We offer SLAs tailored to your level of criticality – such as responding to production errors in 4h.
- We develop the product together – with your backlog or roadmap, which we create together.
- We work on the data – we read what the application says and recommend what to improve or change.

Even before the contract was signed, we received analysis and ideas from SYZYGY that exceeded our expectations.

We don’t just implement applications – we design them to deliver results.
iTaxi – new version of the mobile app:
How we can support you – step by step
Because application development is a process.
We support your product at every stage – from the first workshop to maintenance and development.
You can choose only what you really need – or entrust the whole thing to us.
Technologies & Technological approach
Technology is a means, not an end.
We do not impose a stack – we match it to the product and the team.
We work with different technologies because we know that the application is not an island, but part of a larger system. The team can change. So can the roadmap. That’s why we build so that the project is scalable, readable and independent of a particular vendor – or ourselves.

Stack we prefer to work with:
- Mobile frontend: Swift, Kotlin, Flutter
- Web (PWA): React, Angular
- Backend: js, PHP, Java
- CMS: Magnolia Enterprise, Contentful, Strapi, Sanity
It’s not a catalog – it’s a stack that we select according to the project’s boundary conditions: team, budget, security requirements, required time-to-market and development plans.
Three approaches – matched to the context

For projects where performance, UX
and integration with hardware are critical - e.g., banking, logistics, e-commerce with high traffic volumes.
They allow precise use of the platforms'
capabilities but require two code bases.
We select when we know that what
you gain from nativity is more important than the cost of living.

Consistent UX, faster deployment–
and a single code base - without sacrificing quality.
A good choice when the application
doesn't require deep embedding in the device's functions or you care about fast testing and development using a single team.
We know the limitations and ways around
them - we choose the solution so that the team does not collide with them in a quarter.
FAQ – or questions to answer
Because good cooperation starts with clear rules and open conversation.
How long does it take to create a mobile app?
It depends on the scale and level of complexity.
- Simple MVP product – about 3-4 months.
- More advanced application, with integrations and complex flow – 6-12 months.
We always start by clarifying the goal and the plan – so as not to drag out things that can be built faster.
How much does it cost, more or less?
The creation of the application is the work of a team of several people for several months – that is, a minimum of PLN 500,000.
Smaller projects happen, but we mostly work where the app is meant to be a viable business channel – not just a “business card.”
We’ve been talking openly about the budget from the beginning – we don’t like surprises on either side.
What about the cost of living?
After implementation, the application continues to “live”:
- New iOS/Android versions are coming out,
- need to monitor performance, correct errors,
- develop new features or respond to data from the market.
We offer flexible SLAs to match the pace of your business – such as responding to critical errors within 4h.
Can the application work offline?
Yes – we can implement data caching, offline mode or functions that work without a permanent connection (e.g., viewing saved content, taking notes, generating offline orders).
The range depends on what value this feature has for your users.
Will you integrate the application with our CRM/ERP?
Yes, integrations are a daily occurrence for us.
We work with APIs, SSOs, CMSs, loyalty systems, ERP and CRM.
We always start by looking at what you already have – and how best to connect it to the application. Without plugging things in “by force.”
Will the application be WCAG compliant?
Yes – whenever the project requires it, we design and implement applications in accordance with accessibility guidelines (WCAG).
We can also conduct an audit, identify problems and propose specific solutions – including for people with disabilities.
Can we develop the application further internally?
As much as possible.
We don’t build black boxes – we document the architecture, describe the components, and provide code that can be developed further (with us or independently).
Collaboration with an internal team? We’re a yes – whether it’s ad hoc support or full project handover.
