what we offer


Native App Development

iOS is second of the most popular mobile operating systems in the world, but it’s users are the bigger spenders when it comes to paid applications and in-app purchases. iPhones and iPads are extremely well-designed and offer their users great performance, advanced tools for their everyday needs, and amazing integration between pieces of hardware. Synchronization means that Apple fans usually have more than one product from this brand. And that’s a potential.


Cross-platform Development

Having two apps with one code base makes the development process much easier. Cross-platform development also reduces the time and cost of the project. This solution will help you gain even more clients from different sources. Introducing changes, updates and fixes will happen simultaneously and will be super quick.

what we offer

  • Beautiful iOS applications

    We don’t get left behind! We build our apps using the most advanced tools and following all of the latest alterations and technological novelties provided by Apple. We regularly organize internal training to keep up with the newest solutions, both with software versions and design and architecture patterns. Project created by us won’t be obsolete on the release day. Thanks to being built in modern technologies it will be easier to maintain and update. We are also not afraid of novelties. We will gladly implement AI technologies, bots, or other forms of automation.
  • Scalable and efficient

    Today we are building an MVP for a startup, but tomorrow there might be thousands of customers using this application. Having this in mind we create our software in a way that will allow us to scale it up. Hosting applications in the cloud, which is also our preferred way, makes it even easier to achieve.
  • Secure and efficient iOS applications

    Having many years of experience, we can make the application secure and efficient. By using tested methods we can deliver a project that will meet the highest standards.

see how we work

  1. 1
    Verification of business expectations

    Our business analysts start with finding out what customers' goals are and where the product is on its life cycle curve. We gather all the existing product briefs and technical documentation that will allow us to select appropriate technology stack, plan infrastructure, and create UX/UI design.

  2. 2
    Research and analysis

    Before the actual iOS development process begins, all gathered requirements are matched with possible solutions most appropriate for the customer's business model. Analysis includes future development scenarios, expected integrations, API and backend demands, cloud technologies, scalability, and more.

  3. 3
    Technology recommendation

    Based on all the information collected from step 1 and 2, we recommend the best technology stack for the project. We determine infrastructure integration requirements, verify delivered user experience wireframes and product design.

  4. 4
    iOS team selection

    Our inhouse iOS development team consists of Swift engineers and Flutter developers. We have strong expertise in geolocation services, payment integrations, application security, and working in complex enterprise infrastructure.

  5. 5
    Onboarding & backlog

    We list all the tasks needed to be done according to the best agile development practices and create a Jira backlog. At this stage, there are also testing scenarios defined in order to deliver a top-quality level for the backend prototype, which is available for a customer 24/7 testing on a staging server.
