Frequently Asked Questions
Get Your Questions Answered
Common questions about mobile app development services & solutions, answered.
Cross-platform (Flutter/React Native) is ideal for faster development and cost efficiency. Native development is better for apps requiring platform-specific features or maximum performance. We recommend based on your specific requirements.
Development time varies: simple apps take 2-3 months, complex apps take 4-6 months. Timeline depends on features, platforms, integrations, and design complexity. We provide detailed timelines after requirements analysis.
Yes, we offer comprehensive post-launch support including bug fixes, OS updates, feature enhancements, performance monitoring, and app store compliance. Support packages are tailored to your needs.
Absolutely! We specialize in integrating mobile apps with CRM, ERP, databases, payment systems, and third-party APIs. Our backend development moves data between systems through the same APIs your other tools already use.
We develop for iOS (iPhone/iPad), Android phones/tablets, and cross-platform solutions. Our apps are tested across multiple device sizes and OS versions to ensure compatibility and performance.

We are also ISO/IEC 20000-1:2018 certified for IT service management (certificate 305026051137SM). Certificates are available on request and verifiable with the issuing body.
IP terms are set in your engagement contract rather than by a blanket policy. We agree them in writing before work starts, so ownership of the deliverables, the treatment of any pre-existing or reusable components, and the third-party licences involved are all explicit from day one. Raise it during discovery and the terms go into the proposal.
Not being locked to us is a design goal, not an afterthought — we build on standard, portable technology rather than a proprietary runtime you would have to keep paying for. The specifics of any engagement (where it is hosted, who holds the cloud accounts, exactly what is handed over and when) are agreed up front and written into the contract. Ask during discovery and we will set out what handover looks like for your project.
