Ein-des-ein Mobile App Development Process

Business analysis

We gather requirements and analyze your project goals. We believe that well-defined requirements are essential for successful project delivery. That’s why we pay attention to business analysis and create detailed specifications, roadmaps, user stories, and use cases that will help our designers and developers to collect all the necessary data for decision-making and do their best work.

Product Discovery Phase

We create a roadmap of the project and timelines. You receive a cost estimation with a formal offer from us. This is where we now have a clear path ahead of us, both in terms of project scope and necessary team composition. You can propose ideas, reject, modify and alter, but once we all agree on the direction, we move on to the actual app building.

UX & UI Design

This stage consists of UX wireframing, user testing to work through scenarios related to user moves in the app, and UI design. Once we’re done with prototyping and wireframes, we test the resulting UX design. UI design starts with a style guide that includes a comprehensive set of design standards for UI elements and in-app interactions. This is an important stage for establishing brand identity. Finally, we turn wireframes into actual app screens.

Mobile App Development

Our team works on app architecture and looks at test cases. Then does all the actual front-end and back-end development. We take care of high-quality development and follow the best programming practices to ensure that your solution will be quick, stable, and consistent.

Testing & Deployment

Once the product is done, we deploy your project and monitor its performance. We’ll use various tools to benchmark your app for loading, responsiveness, and speed.

Project kick-off & Evaluation

Your app project is now live! We evaluate its progress and make all the necessary adjustments and iterations when needed. We keep monitoring your app performance after the launch to make sure everything works well.

Questions you may have

How much does it cost to develop an app?
We estimate each project cost individually. The cost depends on many factors, including technologies used, app features, and functionality. The starting numbers for simple apps are usually $10,000+. The more detailed your requirements are, the faster we calculate the final cost that depends on how complex or custom your app needs to be.
Will I have a dedicated team that will work on my project only?
Everything depends on the particular project length and complexity. For the projects that last more than 4 months, we create a standalone team that is fully dedicated to your project.
Can you also design my app?
Yes, we are a full-cycle design & development agency. We apply a design-driven approach to build modern apps and websites. Our team has a strong mix of design and development professionals.
Do I get to keep the ownership and the code of my application?
Yes, absolutely. You are protected by the contract. After the project is finished, you are the sole owner of the Intellectual Property rights and the code.
How is your team usually structured?
We create teams for each project according to the client’s needs. Our typical development team consists of 1 Project manager/Business analyst, 1 Test Engineer, 1 quality assurance engineer, 3 mobile app developers (for both platforms, iOS and Android), and 2 UX|UI Designers.
What technologies do you use?
We use different technologies to develop reliable frontend, backend and infrastructure. We produce a high-quality code to deliver products with great scalability.
Do you help with app maintenance after the project is over?
Once the project is completed, we can come up with a range of maintenance agreements. Some apps require very little ongoing development and maintenance, so just a few hours per month are required to fix bugs, update dependencies, etc. Other apps require ongoing development to add additional features. We’ll work together with you to define what kind of ongoing work may be required, and tailor a plan according to your needs.
