Frequently Asked Questions
- Should I build a web app or a mobile app?
- Web apps are easier to release and iterate on - no app store reviews, instant updates and accessible via any browser. Choose web when you need rapid iteration, SEO visibility or when your users primarily work on desktop. Mobile apps are better for heavy native feature usage and consumer engagement.
- What is a Progressive Web App (PWA)?
- PWAs are web apps that feel like native apps. They work offline, support push notifications, can be installed on home screens and load instantly. PWAs are a great middle ground when you want app-like features without the app store overhead.
- Do you build responsive websites?
- Yes, all our web development is mobile-first and fully responsive. We ensure your site works beautifully across phones, tablets and desktops using modern CSS and React components.
- What's the difference between React and Ruby on Rails?
- React is a frontend JavaScript framework for building user interfaces. Ruby on Rails is a backend framework for building server-side applications and APIs. We often use them together - Rails for the backend API and React for the frontend interface.
- Can web apps work offline?
- Yes, using Progressive Web App (PWA) technologies like Service Workers, web apps can cache data and work offline. We can implement offline functionality, background sync and push notifications for web applications.
- How do we get started on a web development project?
- Book a free consultation to discuss your requirements. We'll help you understand the best technical approach for your needs. For larger projects, an App Planning Day creates specifications and wireframes before development begins.
