The most common question we get from founders is: "How much does it cost to build a mobile app?" The most common answer they get from agencies is a number with no basis. This guide breaks down every cost factor so you can arrive at a realistic budget before talking to any vendor.
What Actually Drives Mobile App Cost
Before any number makes sense, you need to understand the variables that move it dramatically. Two projects described as "a food delivery app" can legitimately cost ₹2 lakh or ₹80 lakh depending on these factors:
- Platform: iOS only, Android only, or both (cross-platform vs native)?
- Complexity: Simple info app (10 screens), medium marketplace (30+ screens), complex platform (50+ screens + real-time backend)
- Backend: Does your app need a server, database, real-time features, push notifications?
- Third-party integrations: Payment gateway, maps, SMS OTP, social login, analytics
- Design quality: Template-based vs custom UI/UX with unique interactions
- Team: Freelancer, small agency, mid-size agency, or product studio
Cost Breakdown by App Type
| App Type | Example | India Cost | Timeline |
|---|---|---|---|
| Simple MVP | Directory, static content, basic auth | ₹80K–₹2.5L | 4–8 weeks |
| Medium complexity | Marketplace, booking app, social features | ₹2.5L–₹8L | 3–5 months |
| Complex platform | FinTech, healthcare, logistics, on-demand | ₹8L–₹25L | 6–12 months |
| Enterprise-grade | Multi-tenant SaaS, large-scale platforms | ₹25L+ | 12+ months |
Native vs. Cross-Platform: The Big Decision
This is often the first technical decision and has major budget implications:
- Native (Swift for iOS, Kotlin for Android): Best performance and platform integration. Highest cost — you're essentially building twice. Recommended only when your app has extremely hardware-dependent features (AR, complex camera, NFC).
- Flutter: One codebase, near-native performance, excellent Android and iOS coverage. 30–40% cheaper than native. Google-backed, large talent pool in India.
- React Native: Massive JavaScript talent pool, good for teams with React experience. Slightly more maintenance overhead than Flutter for complex animations.
Our recommendation for Indian startups in 2026: Flutter is the sweet spot. It performs well on lower-end Android devices (critical for India's market — over 90% Android, significant usage on mid-range phones), a single codebase means faster iteration, and maintenance costs are substantially lower long-term.
Hidden Costs Nobody Mentions in Quotes
The development quote is just the beginning. Build these into your budget from day one:
- Apple Developer Account: $99/year (≈ ₹8,300) — required to publish on the App Store
- Google Play Developer Account: $25 one-time (≈ ₹2,100)
- Cloud infrastructure (AWS/GCP/Firebase): ₹3,000–₹30,000/month depending on users
- Third-party API costs: Google Maps (usage-based), MSG91 for SMS OTP, Razorpay (2% + ₹3 per transaction)
- Annual maintenance: Budget 15–20% of your build cost per year for OS compatibility updates, security patches, and dependency upgrades
- App Store Optimisation (ASO): Screenshots, descriptions, keywords, review responses — often ignored, always worth investing in
Freelancer vs. Agency: When to Choose What
| Freelancer | Agency | |
|---|---|---|
| Cost | 30–60% lower | Higher, more predictable |
| Risk | Higher — bandwidth, reliability, bus factor | Lower — team coverage, processes |
| Design quality | Variable, depends on individual | Generally consistent |
| Post-launch support | Often not available | Usually included in agreement |
| Best for | Simple MVPs, very tight budgets, single features | Complex apps, funded startups, long-term products |
How to Build Smarter Without Cutting Corners
- Ship an MVP, not a finished product. Build the 3 core features that validate your hypothesis. Everything else can wait for revenue and user feedback.
- Use proven open-source libraries. Don't pay to rebuild authentication, payments, file upload, or push notifications from scratch — all are solved problems.
- Design for Android first. Over 93% of Indian smartphone users are on Android. Optimise for mid-range Androids (2–4GB RAM) before perfecting the iPhone experience.
- Milestone-based payments only. Never pay more than 30% upfront. Tie every payment to a specific, demonstrable deliverable you've reviewed.
- Secure your source code access. Ensure the contract states code is delivered to a repository you own throughout development — not just at the end. If the agency disappears at month 3, you need to continue.
