appvinio

Appvinio is a Polish app development studio founded in 2018 that specializes in Flutter-based mobile and web applications. The team has shipped over 50 projects with roughly 300,000 active users across 140 countries. Led by CEO Mateusz Wójcik (business and client management) and CTO Rafał Dziuryk (technology and automation), Appvinio began by supporting tech companies but pivoted to focus on startups and B2B clients seeking full-cycle development. The studio won the Mobile Trends Awards 2021 for best mobile app in Poland—an achievement rooted in their insistence on user-centric design and functional clarity.

Services and capabilities

Appvinio divides its offering into three blocks: design, development, and support. The design phase includes design workshops, business analysis, UX/UI design, and branding. They claim business analysis can reduce project costs by 60% and boost success rates by 70%. The development side covers mobile apps, web apps, backend systems, QA, and management dashboards—meaning they handle the full stack rather than just front-end. They also offer ongoing support with SLA agreements and will take over struggling projects from other vendors.

Their workflow is structured around two-week sprints. After an initial meeting where you present the vision, they run a workshop with business, design, and development experts to map functionality. They then produce a written estimate with a project roadmap and technology recommendations, which they present and discuss. Development happens iteratively in sprints, with bi-weekly check-ins to review progress and adjust direction.

Notable work

NawiGo is a navigation app for people with visual impairments—it enables independent movement through metro stations and government buildings. 4GOAL connects young soccer talent with experts through a social sports platform. Vitalia is an e-commerce health app that builds personalized diets. Blisko is a GovTech app used for municipal communication with residents. FoxTeam is a business system managing installation, commissioning, and servicing of inverters and heat pumps. These projects span digital accessibility, GovTech, social media, sports, e-commerce, and health—showing range but not deep specialization in any vertical.

Clients have praised their speed. One product owner at Vitalia noted Appvinio delivered ahead of schedule and "ensured excellent communication." The founder of 4GOAL highlighted their "high professionalism and commitment" and willingness to share industry knowledge. A CEO at IT.Focus noted the team was responsive despite remote work and provided thorough feedback.

How they work

Engagement starts with an initial no-obligation meeting, then a longer workshop focused on business goals and requirements. This produces a multi-page requirements document. Appvinio then delivers a detailed estimate with cost, timeline, and a project roadmap showing phases and investment milestones. Development runs in two-week sprints with sprint-end reviews. Pricing is not published on their site, but they offer preliminary cost and time estimates after the initial conversation. The team operates transparently on billing and working procedures—a stated value they emphasize alongside engagement, quality, and clear communication.
