ASO, feature releases, crash monitoring and continuous iteration.
The mobile stack
Native performance where it matters, cross-platform where it makes sense.
Frequently asked
Native or cross-platform — which should we pick?
Cross-platform (Flutter or React Native) is ideal for MVPs, content and B2B apps. Go native for games, heavy AR/ML, wearables, or when every millisecond matters. We recommend during discovery.
How long does an app take to build?
Simple MVPs ship in 6–8 weeks. Production-grade apps typically take 12–20 weeks. Enterprise apps 4–6 months.
Do you handle App Store submission?
Yes — we submit, respond to review feedback, and hand over the developer accounts. First-time approval rate is over 95%.
How much does a mobile app cost?
MVPs from HK$150K, production apps typically HK$250K–500K, enterprise apps HK$500K+. Fixed quote after discovery.
Do you support the app after launch?
Yes — every launch includes 90 days of hypercare. After that, monthly retainers cover new features, OS updates and crash fixes.
Can you take over an existing app?
Absolutely — we regularly rescue, refactor and modernise inherited codebases. We audit first and give you an honest recommendation.
