What Our Client's Say About Us
Frequently Asked Questions
1. How does StartupLabs compare to hiring in-house US developers vs. standard offshore agencies?
Ans: You get in-house-level accountability and US-aligned communication, without the cost or hiring timeline of building an internal team. Our designers, developers, and QA engineers work under one roof with a single point of contact throughout your project, so nothing gets lost between vendors.
2. How much does mobile app development cost in the US?
Ans: Most custom apps built in the US cost between $15,000 and $250,000+, depending on complexity, compliance needs, and engagement model. An MVP typically starts at $15,000–$45,000, while enterprise-grade apps with real-time architecture and strict compliance run $120,000–$250,000 or more.
3. How long do app development services typically take?
Ans: The timeline for our mobile app development services depends on project complexity. Standard applications or MVPs typically take 8 to 12 weeks to build and launch. More complex enterprise applications featuring custom integrations, advanced security, and deep backend infrastructure generally require 4 to 6 months.
4. Can you integrate with enterprise systems?
Ans: Yes, our mobile application development services company excels at seamless enterprise integrations. We securely connect your mobile app with existing legacy systems, including ERPs, CRMs (like Salesforce), cloud databases, and custom third-party APIs, ensuring real-time data synchronization and optimized operational workflows.
5. Who owns the source code and intellectual property (IP)?
Ans: You own 100% of the code, designs, and IP outlined in your contract once the project is paid in full. Any third-party libraries or licensed components remain under their original licenses, and we document exactly what’s custom-built versus licensed.
6. Do you sign NDAs before initial discovery calls?
Ans: Yes, we sign a mutual NDA before any product details, data, or business logic are discussed. You’re welcome to use your own NDA template, or we can provide a standard one to get started quickly.
7. How do you ensure compliance with US regulations (HIPAA, PCI-DSS, Accessibility)?
Ans: We design and build apps to align with HIPAA data-handling practices, PCI-DSS payment security standards, and ADA/WCAG accessibility guidelines. For regulated industries, these requirements are built into the architecture and QA process from day one, not bolted on after launch.
8. What's the difference between building natively vs. using Flutter/React Native?
Ans: Native apps (Swift/Kotlin) offer the best performance and platform-specific features; cross-platform apps (Flutter/React Native) launch faster and cost less by sharing one codebase across iOS and Android. The right choice depends on your budget, timeline, and how much you rely on device-specific capabilities.
9. What happens if we need to change features or scope mid-project?
Ans: We log every change request and give you clear options before proceeding: absorb it within the current budget, push it to a later phase, or expand scope with a revised estimate. This keeps your timeline and budget predictable, even as requirements evolve.
10. Do you provide ongoing SLA maintenance and post-launch app support?
Ans: Yes, we offer SLA-backed post-launch support, including bug fixes, OS compatibility updates, performance monitoring, and new feature development, available as a one-time package or an ongoing monthly retainer.
