FAQs
What is the difference between a general app development company and an AI app development company?
A general app dev company builds user-facing interfaces. An AI app development company builds smart systems that learn, recommend, or predict, then wraps them in a good UI. You need both to build something meaningful in 2025.
Is it better to hire a U.S. team or go global?
If the budget isn’t a blocker and you want product + strategy input, U.S. teams are strong. But for startups optimizing burn, hybrid setups—e.g., a mobile app development company in Singapore with U.S. product managers can give you both quality and cost control.
What’s trending in AI app development in 2025?
- On-device AI (thanks to Apple Intelligence & Gemini Nano)
- Generative AI UI (tools that create content, visuals, workflows)
- AI copilots for vertical SaaS
- Multimodal AI apps (text + voice + image)
- Edge-friendly apps with tiny models
How long does it take to build an AI MVP?
With a focused team (like Netscape Labs), 6–8 weeks is standard. For enterprise-grade platforms, expect 3–6 months minimum.
Can I add AI to my existing app?
Yes, but only if your app’s architecture is ready. A smart AI app development services partner will audit your tech stack first. Sometimes it’s easier to rebuild core parts than force AI into outdated code.
