One agency quoted ₹4 lakh. Another quoted ₹25 lakh. Same app brief. Both legitimate agencies. Here's why costs vary and how to budget without being blindsided.
What Drives App Development Costs
The four biggest cost factors:
- Platform choice — iOS only, Android only, or both (cross-platform)
- Backend complexity — Does the app need a server, database, real-time features?
- Design requirements — Template UI vs custom animated interfaces
- Third-party integrations — Payment gateways, maps, notifications, social login
Cost by App Type
Simple App (basic features, standard UI)
- Freelancer: ₹4–8 lakh
- Small agency: ₹8–15 lakh
- Examples: Task tracker, simple booking app, basic directory
- Timeline: 8–12 weeks
Medium Complexity App
- Freelancer: ₹10–20 lakh
- Small agency: ₹18–35 lakh
- Examples: E-commerce app with cart/payment, food delivery clone, service marketplace
- Timeline: 3–5 months
Complex App
- Agency: ₹35 lakh–1 crore+
- Examples: Social platform, real-time logistics, fintech with compliance
- Timeline: 6–12+ months
Flutter vs React Native vs Native

Flutter
- Best for: Most projects
- Performance: Near-native
- Code reuse: 95%+ across iOS and Android
- UI flexibility: Excellent — builds beautiful custom UIs
- Cost advantage: Single codebase = roughly 40% less than native
React Native
- Best for: Teams with React/JavaScript background
- Performance: Good (slightly below Flutter for complex UIs)
- Code reuse: 85-90%
- Ecosystem: Large, many ready components
Native (Swift/Kotlin)
- Best for: Apps needing maximum platform performance (games, AR)
- Cost: 1.5-2x Flutter/React Native (separate iOS and Android teams)
- When justified: Complex hardware integrations, premium performance requirements
Our recommendation for most projects: Flutter. It's faster to build, looks great, performs excellently, and one team handles both platforms.
Hidden Costs
- App Store fees: Apple Developer Program – $99/year; Google Play – $25 one-time
- Backend hosting: ₹3,000–15,000/month (AWS/GCP/Firebase)
- Push notifications service: Free at low volume; paid for scale
- Payment gateway: Razorpay/Stripe take 2% per transaction
- Post-launch maintenance: ₹10,000–25,000/month (bug fixes, OS updates, new features)
- App Store compliance updates: iOS and Android release new requirements annually
What a Realistic Budget Looks Like
For a typical Indian startup app:
- Development: ₹12–18 lakh
- Design (if separate): ₹3–5 lakh
- Backend setup: ₹2–5 lakh
- Testing: Included in good agencies, ₹2–3 lakh separately
- Year 1 total (development + maintenance + hosting): ₹20–30 lakh
Before You Build: Validate First
Before spending ₹15 lakh on a full app:
- Build a simple MVP — just the core feature, no polish
- Get 50-100 users using it
- Validate they'll pay
- Then build the full product
An MVP typically costs 30-40% of a full build and saves most startups from building the wrong thing.
