We work remotely with clients across the country, and we're always happy to meet in person too. Book a call Contact us Frequently Asked Questions How long does it take to build a mobile app? A typical MVP takes 3-4 months to develop. More complex apps with multiple integrations may take 6+ months. We recommend starting with our App Planning Day to define scope and create realistic timelines for your specific project. Do you work with startups or only established companies? We work primarily with funded startups and scaleups. Our sweet spot is companies with seed to Series B funding who need experienced technical partners for greenfield builds and MVP development. What technologies do you specialise in? Our core expertise is React Native for cross-platform mobile apps and Ruby on Rails for web applications. We also work with React, Next.js, TypeScript, and modern cloud infrastructure on AWS, GCP, and Azure. Do you provide ongoing support after launch? Yes, we offer comprehensive support and maintenance services. This includes bug fixes, security updates, performance optimisation, and feature development to ensure your app continues to perform well after launch. Can you help with an existing app that needs improvements? Absolutely. We regularly perform code reviews and technical audits of existing React Native and Rails applications. We provide actionable recommendations and can implement improvements or hand off to your team. Do you work remotely or only in Scotland? We are based in Glasgow but work with clients across the UK and internationally. Most of our work is done remotely with regular video calls and async communication, though we're happy to meet in person when needed.
