Why Costs Vary So Much
App development costs vary because "app" means wildly different things. A simple booking form is an app. Uber is an app. The gap between them is 100× in cost and complexity. The main cost drivers are: number of user roles and their distinct experiences, complexity of business logic (simple CRUD vs real-time systems), third-party integrations (payment gateways, maps, SMS, etc.), design requirements (standard components vs custom pixel-perfect UI), and infrastructure requirements (simple hosting vs auto-scaling distributed system).
Mobile App Development Costs
Simple app (1–2 screens, basic functionality, no backend): ₹2–5L. Standard app (5–10 screens, user auth, database, basic backend): ₹5–15L. Complex app (15+ screens, real-time features, payment integration, admin panel): ₹15–40L. Enterprise app (complex workflows, multiple integrations, high compliance requirements): ₹40L+. These are for cross-platform (Flutter/React Native) builds for both iOS and Android. Native builds (separate iOS and Android codebases) add 40–60% to the cost.
Web Application Development Costs
Landing page / brochure site: ₹50K–2L. Simple web app (form, database, dashboard): ₹3–8L. Standard SaaS product (auth, billing, multi-user, core features): ₹8–25L. Complex platform (marketplace, real-time, advanced permissions): ₹25–80L. These are development costs only — design, infrastructure, and ongoing maintenance are separate.
What Affects Your Quote
Things that push costs up: custom UI/UX design (vs standard component libraries), real-time features (chat, notifications, live updates), payment gateway integration, third-party API integrations, compliance requirements (HIPAA, PCI-DSS), admin panel complexity, and multi-language support. Things that push costs down: using standard component libraries, simple linear user flows, SaaS APIs instead of custom implementations, phased development (MVP first), and clear, documented requirements.
The Hidden Costs to Budget For
Beyond development, budget for: UI/UX design (15–25% of development cost), project management (included at Knacode, but verify with other agencies), hosting and infrastructure (₹5–50K/month depending on scale), third-party service costs (SMS, email, maps, payment processing), App Store developer accounts (₹7,500 Apple + free Google), post-launch bug fixes and iterations, and ongoing maintenance (budget 15–20% of development cost per year).
How to Get an Accurate Quote
The best way to get an accurate quote: write a one-page brief describing what your app does, who uses it, and what it must do on day one. Share that brief with 3 development companies and compare. Be wary of quotes significantly below or above market range — very low quotes often mean missed scope; very high quotes don't always mean better quality. Ask for references and look at actual products the company has shipped, not just case study numbers.
