Our top-notch Mobile Application Development Services
Ventures as well as established businesses rely on mobile apps to get closer to their customers and to build up trusted communication and sales channels.
That a mobile application is truly used and deemed worthy by users, extensive user and market research is required. Our team analyses market structures, competition and user desires to create a product vision which is engagening and competitive.
During the design stage, we test and verify user-desired features by creating outstanding user journeys. Consistent and balanced technical specifications reassure the smooth coding process as well as the agreed upon application development time and budget. Proprietary development frameworks and integrated best practices guarantee highest standards of the written code.
Our mobile app development services enable short time-to-market timelines, ensure high-quality standards, and allow greatest development flexibility. We develop a product, test it, and finally launch it. To understand how the app performs,we onboard the first users and collect their feedback. After analysing the feedback, we prepare a list of possible improvements and adaptations. This allows our clients to receive solutions which are market-proved and guaranteed successful.
Customer stories
4х revenue growth with new AI functionality
Koko Face Yoga is an AI-driven mobile application that creates a personal yoga class experience when and where you need it.

The client desired to add automated user interactions to correct their mistakes and help them to achieve progress. At the design stage, we discovered low functionality of the existing application and issues with the paid content that resulted in bad marketplaces reviews.

Detecting incorrect face positions by AI functionality has provided "a yoga teacher" effect. Enhancing the trial feature and switching on personalization not only boosted ranking reviews in the Apple Store and Play Market but also achieved 3x growth in the number of subscribers and 4x in total earnings.

Mobile App Development Workflow
For creating user-centric and user-desired mobile apps, we use our R2D Product Growth framework. The R2D Product Growth framework consists of a series of iterations that solve three key objectives for our clients:
The R2D Product Growth Framework is a roadmap of a project that we assemble from necessary 2-week cycles depending on the business needs. According to this framework, a high-level roadmap looks like this:
R2D Product Growth Framework
To create our proprietary framework, we integrated all development stages with their respective best practices.
The main idea of the framework is that during the development of the product, we constantly prioritize the tasks required to be solved ASAP and proceed to the respective cycle. This approach allows us to run two or more cycles in parallel. Our R2D framework is a practice-oriented approach that has been used to deliver more than 250 successful software development projects. Unlike Agile, for each cycle, our framework offers proven results-driven stages and methods, which were carefully evaluated and chosen over the span of 10 years across hundreds of development projects.

The framework allows you to reach the expected results, transform chaotic ideas and feedback from the market into specific features, and keep on continuously delivering values to users in a changing market.

Mobile app development services for various industries
We deliver superior mobile apps for SMEs as well as enterprise-sized companies from a wide range of industries.
What our clients say about us:
How much does it cost to develop a custom mobile application?
We would love to provide you with a short and specific answer to this question, but the reality of custom mobile app development is more complex. The costs depend on various factors such as the selected tech stack, the complexity of features, the team size and the project architecture. However, that is no reason to worry! After an initial consultation with our experts, you will receive a cost and time estimate for your project.
What technology should I use for my mobile app?
We don't recommend any hype-driven tech stack that doesn't have an industry-trusted future and roadmap. We suggest a proven set of tools and technologies that will not just solve the original problem but provide you with a longevital software with simple maintenance requirements. Based on your task, we'll recommend the most suitable tech stack.
How do you support and maintain a mobile application?
We put together a support and maintenance plan after aligning with the client on their product growth strategy. The ideal scenario is retaining the development team that was involved in building the first version of the app and iterating based on the customer feedback. However, it's also possible to scale down the development effort after the initial launch and focus on keeping the server infrastructure intact. In any scenario, we are here to support you as your custom software evolves.
What would I need to do as a client to launch a mobile application with a software development team?
Even though we have all the skills required to design and build a robust mobile application, alignment with the client's vision is crucial. That's why we would need 3-6 hours of your time per week throughout the discovery and design phase of the project. As we progress with the development, the client's involvement decreases to less than 1-2 hours per week. In case of mobile app development, we also ask the client to create an App Store or Google Play account to retain full control of the product once it's launched.
