Common Questions
Answers to the questions we hear most often about our services.
For web we primarily use Next.js and React, paired with Node.js, Python, or Go on the backend. For mobile, we build native apps with Swift (iOS) and Kotlin (Android), or cross-platform apps with React Native or Flutter - the choice depends on your budget, timeline, and performance requirements.
A typical marketing website takes 4-6 weeks. A native mobile app takes 8-14 weeks. Complex web or mobile applications can range from 12-20 weeks. During discovery we provide a detailed timeline with milestones.
Yes. We handle the entire submission process including store listing optimization, screenshot design, compliance with Apple and Google guidelines, and managing review feedback.
It depends on your priorities. Native gives the best performance and platform-specific UX. Cross-platform (React Native, Flutter) is more cost-effective when you need both iOS and Android on a tighter budget or timeline. We advise based on your specific use case.
Yes. We offer flexible maintenance retainers covering security patches, OS update compatibility, uptime monitoring, and priority bug fixes. Many clients keep us on retainer for continuous feature development after launch.
