Client Reviews

What clients say about our mobile app development

"

Our React Native driver app handles 50K daily deliveries. Nexcode built it in 12 weeks and the offline-first architecture they designed has been bulletproof. We've had zero critical crashes in production.

Our engineers answer β€” not a sales team.

Ask a Question β†’
React Native vs Flutter β€” which should I choose?+
Both are excellent. We recommend React Native if your team has React/JS experience or you're sharing code with a web app. Flutter if you want pixel-perfect custom UI and don't have an existing web codebase. Both deliver near-native performance β€” the choice is more about team fit and UI complexity.
How much does a mobile app cost?+
A straightforward consumer app typically costs $25,000–$60,000. Complex apps with real-time features, payments, and custom UI range from $60K–$150K. We give a fixed-price quote after a discovery call.
Do you handle App Store and Google Play submission?+
Yes, completely. We create or transfer developer accounts, prepare all store assets (screenshots, descriptions, keywords), handle the review process, and respond to any rejection notes. ASO is included.
How long does a mobile app take?+
A well-scoped app takes 10–14 weeks from kick-off to App Store approval. Complex apps with custom backends can take 16–20 weeks. The App Store review adds 1–3 days for iOS.
What about maintenance and updates?+
We offer monthly maintenance plans from $2,000/mo covering OS updates, dependency upgrades, crash monitoring, and bug fixes. iOS and Android each release major versions annually β€” staying current is important.
