Custom App Development Cost Guide 2025
Real cost ranges for building custom web and mobile apps in 2025, from a focused MVP to a full product. Based on Go-Orca's actual project history.
MVP / Prototype
Core feature set only. No polish, but functional and shippable.
$8,000–$25,000
2–5 weeks
Web App (internal tool)
Internal dashboard, admin panel, or client portal with auth and data management.
$15,000–$45,000
4–10 weeks
Customer-facing web app
Public-facing product with user accounts, billing, and full UX design.
$25,000–$75,000
6–14 weeks
Mobile app (iOS + Android)
React Native app for both platforms with custom UI, push notifications, and offline support.

What drives custom app development cost?
- Number of screens / features — each distinct feature area adds 1–3 weeks of development time.
- Design complexity — a fully custom UI designed from scratch adds 20–40% to cost vs using a component library.
- Integrations — each third-party API integration (payments, email, maps, ERP) adds $1,500–$5,000 depending on complexity.
- Platform — web-only is cheapest; adding iOS + Android adds 30–50% to a web build; native apps cost 2–3× more than React Native.
- Real-time features — live collaboration, chat, or WebSocket-heavy features add significant backend complexity.
- Compliance — HIPAA, SOC 2, GDPR-compliant architectures add 20–40% to infrastructure and development cost.
Why do agency quotes vary so much?
A $10,000 quote and a $80,000 quote for “the same app” usually means they're scoping completely different things. The cheap quote typically excludes: UX/UI design, QA, deployment, documentation, and post-launch support. The expensive one often includes offshore team management overhead. Our quotes include everything needed to ship and maintain a production-ready app.
How does Go-Orca price projects?
We give you a fixed price after a 20-minute discovery call. That price covers design, engineering, QA, deployment, and 30 days of post-launch support. No surprises, no hourly billing, no scope creep games.
