Frequently Asked Questions
How much does it cost to build a mobile app in 2026?
Mobile app development typically ranges from $11,000 for a simple app to $60,000+ for a complex multi-platform application. The biggest cost drivers are complexity (number of screens and features), platform choice (iOS, Android, or cross-platform), design requirements, and timeline. Use the calculator above to get a personalized estimate based on your specific needs.
How much does a web app cost?
Web application development starts around $6,000 for simple apps like marketing sites and dashboards, and ranges up to $40,000+ for complex platforms with multiple user roles, integrations, and advanced features. A medium-complexity web app with authentication, an admin dashboard, and payment processing typically falls in the $15,000–$25,000 range.
Is cross-platform cheaper than building separate iOS and Android apps?
Yes. Cross-platform development with React Native lets you reach both iOS and Android with a single codebase, typically saving 30–40% compared to building two separate native apps. For most small businesses, cross-platform is the right choice. We recommend native development only when you need maximum performance or deep hardware integrations.
Can you add features to my existing app or website?
Absolutely. Select "Feature / Integration" in the calculator to estimate standalone features like AI chatbots, payment integrations, booking widgets, or workflow automations added to your existing site or application. These projects typically start around $2,000 and scale based on complexity.
Why does a faster timeline cost more?
A compressed timeline means we prioritize your project above other work, which requires focused sprints and sometimes weekend or extended hours. Our 30-day MVP sprint carries a premium because you're getting a launchable product in a fraction of the typical timeline. Conversely, a relaxed 6-month schedule lets us batch work efficiently, which reduces your cost.
What's included in the estimate?
The estimate covers development, basic testing, and deployment. Design is factored in based on your selection. Every project also includes 30 days of post-launch support through our TideWatch service. The estimate does not include third-party service costs like hosting, domain registration, app store fees, or API subscription fees – we'll outline those during discovery.
How accurate is this calculator?
The calculator provides a realistic ballpark based on our actual project history. Final pricing depends on specifics we determine during our Nautilus discovery session – things like API complexity, data migration, third-party licensing, and compliance requirements like HIPAA. Most final quotes land within the range shown.
Do I own the code?
Yes. You own 100% of the source code and IP we build for you. Take it, hire your own team, modify it however you want. If you choose to license the software to others, we may take a small equity stake in the licensed product – but the code is always yours. Learn more on our custom software development page.
