Mobile App Development FAQs

Common questions about app development timelines, costs, and technology

Should I build native or cross-platform apps?

+

Native (Swift/Kotlin) offers best performance and platform-specific features, ideal for complex apps. Cross-platform (React Native/Flutter) reduces development time and cost by 40%, perfect for MVPs and apps without hardware-intensive features. We assess your requirements and recommend the optimal approach.

How long does mobile app development take?

+

MVP: 6-8 weeks. Full-featured app: 12-16 weeks. Enterprise app: 4-6 months. Timeline depends on complexity, features, and platform choice. We use agile sprints with bi-weekly releases so you see progress continuously.

What's the cost of developing a mobile app?

+

Simple app: $25K-$40K. Medium complexity: $40K-$80K. Complex enterprise app: $80K-$150K+. Cross-platform development reduces costs by 30-40% vs building separate native apps. We provide detailed quotes after requirements analysis.

Do you handle App Store and Google Play submission?

+

Yes, we manage the entire submission process including app store optimization (ASO), screenshots, descriptions, and compliance. We have a 100% approval rate and handle any review feedback or resubmissions.

Can you integrate my app with existing systems?

+

Absolutely. We integrate with CRMs (Salesforce, HubSpot), payment gateways (Stripe, PayPal), analytics platforms, ERPs, and custom APIs. We build secure REST or GraphQL APIs if your backend needs modernization.

What about app maintenance and updates?

+

We offer ongoing support packages including bug fixes, OS compatibility updates, feature enhancements, and performance monitoring. Typical maintenance is 15-20% of initial development cost annually. Critical security patches are deployed within 24 hours.
