How do we craft a success story for you? Our experts start with effective business analysis. To turn your app idea into reality, we need to analyze your audience, market and business needs. We check which features and functionalities are the most useful in your case. A mobile app offers a variety of possibilities to increase your marketing efforts. It connects you with customers on a whole new level and allows you to increase user engagement. Mobile apps have the ability to send push notifications, to remind people about you and encourage them to interact with your brand. You can easily send personalized offers and build a direct marketing strategy using relevant features. What is more, the app gathers reliable information about users and their behaviour to optimize your tactics and increase customer retention. Together we will figure out what you need to succeed.

After choosing the best solutions for your app, our designers craft impressive UX/UI and developers write a code. The app will attract and retain users’ attention thanks to a delightful design and usability. Code quality, security, performance and scalability are crucial to create a successful product. Reliable backend is the foundation of your app: perfectly-working infrastructure and API built with cutting-edge technologies. With optimized frontend and perfectly chosen frameworks, you will reach users on iOS, Android and web easily and cost-effectively.

The Road to Your Success Story

1. Workshops and research

Let’s begin with validating your idea, discovering business needs and getting to know your target audience.

Starting a project with workshops and research keeps us all on the same page. Together, we validate your product market fit, create user personas, empathy maps and value propositions. We set up goals and analyze your audience, which keeps every member of the team focused. Then, we prepare a map of your application and determine all functionalities needed. You choose if you want to begin with an MVP or to create a full-featured product.

2. UX design and prototype

We start with wireframes, then create excellent UX and craft amazing interface. It will impress your users and make them come back for more.

Modern design is one of the things your app should do better than the competition. If you want to begin with an MVP, we create designs for the main functionality and features. Then, we polish it and work on the UX/UI side of your final product. Our designers are a part of your whole app development team. They communicate with developers and you directly. There’s no friction in providing UX/UI guidelines and passing the project further.

3. App development and testing

Your app is developed and tested in sprints. Each sprint pushes your project forward, and we keep you in the loop. Agile development makes your app easy to scale.

We organize projects according to Agile and Scrum: in two-week sprints, prepared on the grounds of specifications and project backlog. After each sprint, we meet with you on a demo day, present the progress and gather feedback. We use tools like Jira, where you can track the progress, and Slack to communicate. Our frontend and backend developers keep the code easily-maintainable so any change can be added quickly. We test all the elements of your app already after they are created. Quality assurance, automated tests, peer code reviews, usability tests: we make sure everything works perfectly and is bug-free. A code review is a crucial part of the development process. We can start the development process with creating an MVP – the first, simple version of your app, with only one functionality – to get you on the market as quickly as possible, and then, work on the final product.

4. Launch and maintenance

Your app is ready. It’s easy to maintain, and any change can be added easily in the future. We provide support for you.

When the development and testing are finished, we deploy your app to app stores. Then, we gather and analyze users’ feedback. If anything is wrong, we fix it. Your app needs regular updates and maintenance services. We support you all the way. If you want to expand your product, that is the time when we set up further steps.

Cross Platform Mobile App Development

The cross-platform approach allows you to save time and money with no sacrifices. It’s the fastest and most efficient way to develop apps for iOS and Android. Developers need to create only one code that works for both platforms, on billions of devices. 

We love to craft cross-platform apps with Flutter and Ionic. Experience shows that these frameworks work best for our clients. We also have a set of battle-tested backend tools. Our team will choose the best technology stack to meet your business goals.
