The pros of building your mobile app with Curiosum
Top Productivity
With our React Native technology of choice, app developers can quickly create rich, interactive mobile applications by writing minimal code with low cross-platform overhead, significantly reducing development time. This boosts productivity as it allows for rapid feature development and easier maintenance of component-based codebases.
MVP Development & Scaling
A mobile application is a great way to validate your business in terms of product-market fit. With state-of-the-art frontend, mobile and backend technologies we use at Curiosum, you'll not only get a Minimum Viable Product for the initial stages of your business outreach - the MVP will already be built with scalability in mind so your product can continue to grow.
Focus on Product Design
Curiosum pays special attention on User Experience research and UI Design so that mobile apps we ship for you follow best practices in appearance, accessibility and internationalization. We encourage you to team up with us to work together on finessing your ideas, from ideation to product strategy and execution. We are excited to participate in the digital transformation of your business.
Cross-Platform Operation
With the React Native technology we use for our custom mobile apps for iOS & Android, both leading platforms share a single codebase - thus allowing to cut down on development costs and shorten your solution's time to market.
AI & Machine Learning-powered mobile apps
Teaming up with Curiosum to build mobile apps lets you dive deep into the world of Artificial Intelligence & Machine Learning - to turn your mobile application into an intelligent assistant or enable it to use generative & analytical AI for the benefit of user experience and business value.
Great User Experience
We use React Native to deliver smooth, snappy user experiences just as native Android & iOS apps do, but without the necessity to split work between Kotlin and Swift code. Users enjoy fast, dynamic interactions within the app, leading to higher engagement and satisfaction. There is no uncanny valley effect - the UI is native, not almost native.
App Modernization
Take your existing mobile application to the latest standards, migrating a legacy application to modern tech with us. Use our vast experience in refactoring, modernizing, and reworking legacy applications and codebases to relieve you from costly technical debt and help you focus on business growth.
Quality Assurance
We implement stringent quality assurance measures to all mobile solutions we develop, both in the mobile application and on the server side, performing automated and manual testing alike - tailored to the needs of your specific use case.
Check out our projects

Curiosum enabled our team to develop a complete platform despite their lack of prior knowledge about Elixir stacks. In addition, their team impressed the client with their honesty, integrity, availability, and efficiency.

I'm very satisfied with the deliverables and impressed with the partnership. Curiosum is efficient and communicative team.

Curiosum helped us substantially to introduce OTP and caching concepts into out app as well as formulate the increasingly complex API in a concise manner. They played essential role in the development of our product.

Curiosum team have been great to work with, and we would certainly recommend them. Both of the developers we've had from them have been talented, hard working and a great asset to our team.

Curiosum team has adapted very well to the way we work and has been able to give valuable contribution to our overall product development.

Thanks to Curiosum, the platform now supports 10 times more users within the same server capacity. Also, external and internal stakeholders are happy with the quality of the application. Overall, the team works seamlessly through two-week sprints, using Slack and Jira for project management.

Finding experts in the tech stack we use - Elixir, Phoenix, React, GraphQL - is not easy. Curiosum understood our business perspective well and offered valuable feedback. That is exactly what we expect from our outsourcing partners.
