What a mobile app agency handles for you
Building an app is far more than writing code, and a real agency owns every part of it. We start with product discovery — turning your idea into a clear feature list, user flows and a realistic budget. Then comes UI/UX design, development, backend and API work, third-party integrations like payments and maps, testing on real devices, app store submission, and post-launch support. The value of an agency over a solo developer is that no single point of failure can stall your project, and there is a documented process behind every decision. At Cyber Defence you deal directly with me and a small senior team, not a call-centre account manager. We keep scope honest, timelines realistic and communication in plain English, so a first-time founder understands exactly what is happening at each stage. From concept sketch to a live listing on Google Play and the App Store, you have one partner accountable for the outcome.
Types of apps we build
We build across categories so your idea is not limited by our comfort zone. Business and service apps for bookings, appointments and customer engagement. E-commerce and delivery apps with carts, payments and order tracking. On-demand apps for salons, tutors, home services and logistics. Content and community apps with feeds, chat and notifications. Internal tools like field-staff apps, inventory and CRM companions. We also build MVPs for startups who need to test an idea in the market fast without burning their whole budget. Most projects are cross-platform using Flutter or React Native so you get one codebase running on both Android and iOS — cheaper and faster than building twice. When performance or platform-specific features demand it, we build native in Kotlin or Swift. Every app ships with a secure backend, admin panel, push notifications and analytics, so you can see how real users behave and iterate with confidence.
Our tech stack and engineering approach
The right technology decision at the start saves you lakhs later, so we choose deliberately. For most projects we recommend Flutter or React Native — a single codebase for Android and iOS cuts cost and keeps both versions in sync. Backends run on Node.js or Laravel with MySQL, PostgreSQL or Firebase depending on scale and real-time needs. We integrate Razorpay, Stripe, Google Maps, Firebase notifications and any APIs your app requires. As a CEH-certified developer I take app security seriously: encrypted storage, secure token-based authentication, protected APIs and safe handling of user data, so a breach does not become your launch-day headline. We use version control, staging builds and structured QA on real devices across screen sizes before anything reaches the store. You get clean, documented code that another developer could pick up — no lock-in, no black boxes. The goal is an app that is stable, secure and cheap to maintain, not just one that demos well.
Why choose Cyber Defence for your app
App projects fail more often from poor communication than from bad code, so that is where we are different. You work directly with a certified developer who explains trade-offs honestly instead of dazzling you with jargon. Fixed, itemised quotes mean no mid-project "the scope grew" surprises. Direct WhatsApp access means you are never stuck waiting days for a reply. I will happily tell you when your idea should launch as a lean MVP for ₹1.5 lakh rather than a bloated ₹8-lakh build you cannot yet justify — because I would rather earn your next three projects than overcharge you once. We do not disappear after submission; there is a warranty period and optional maintenance. And because security is my core certification, your users' data is handled the way it should be. That mix of honesty, senior engineering and long-term support is what a good agency should mean, and rarely does.
Our app development process
A predictable process is what keeps app budgets from spiralling. It starts with a discovery call to understand your idea, users and budget — free and pressure-free. Next is a written proposal with fixed price, feature scope and timeline, plus a recommendation on MVP versus full build. Then design: user flows and screen mockups you approve before development begins. Development happens in sprints with regular builds you can install and test on your own phone, so there are no surprises at the end. We test rigorously across devices and OS versions, then handle Google Play and App Store submission, including the paperwork and store assets. After launch you get a warranty window for bug fixes and optional ongoing maintenance for updates and new features. You sign off at each stage, so the app that lands in the store is the one you shaped throughout — not a mystery reveal on delivery day.
Transparent app development pricing
App pricing is where agencies love to be vague, so here are honest ranges. A simple app — a few screens, basic backend, one or two integrations — typically costs ₹80,000 to ₹2,00,000. A mid-complexity app with user accounts, payments, real-time features and an admin panel runs ₹2,50,000 to ₹6,00,000. Complex, multi-role platforms with heavy custom logic go higher and are quoted per scope. A lean MVP to validate your idea often fits ₹1,00,000 to ₹2,50,000. Every quote is fixed before we start and itemised so you see exactly what each feature costs — useful when you want to trim scope to fit a budget. Payment is milestone-based across the project, never a per-hour meter. If your budget is genuinely tight, tell me and I will help you sequence features so you launch something real now and add the rest as the app earns.
Cross-platform vs native: which should you pick
This one decision shapes your whole budget, so here is the honest verdict. Cross-platform (Flutter or React Native) means one codebase runs on both Android and iOS — you save roughly 30 to 40 percent versus building twice, updates stay in sync, and for the vast majority of business, e-commerce and on-demand apps the performance is indistinguishable to users. Native (Kotlin for Android, Swift for iOS) means two separate codebases, higher cost, but the best possible performance and access to every platform-specific feature — worth it for graphics-heavy games, AR, or apps pushing hardware limits. My default recommendation for most clients is cross-platform, because it delivers the same experience for less money and is cheaper to maintain. I only steer you to native when your specific app genuinely needs it, and I will explain exactly why rather than defaulting to the more expensive option because it pads the invoice.

Frequently Asked Questions
How much does it cost to hire a mobile app development agency in India?
A simple mobile app in India costs ₹80,000 to ₹2,00,000, a mid-complexity app with payments and accounts runs ₹2,50,000 to ₹6,00,000, and complex platforms cost more. A lean MVP often fits ₹1,00,000 to ₹2,50,000. Cyber Defence gives a fixed, itemised quote upfront so you know exactly what each feature costs.
How long does it take to build a mobile app?
A simple app takes about 4 to 8 weeks, a mid-complexity app 3 to 5 months, and a complex platform 6 months or more. An MVP can sometimes launch in 6 to 10 weeks. Timelines depend on features and how fast you give feedback. We agree a delivery date in writing and share test builds throughout so you see progress.
Should I build a cross-platform or native app?
For most business and e-commerce apps, cross-platform (Flutter or React Native) is the better choice — one codebase for Android and iOS saves 30 to 40 percent and keeps both versions in sync. Native is worth it only for graphics-heavy games, AR, or apps needing maximum performance. We recommend cross-platform by default and native only when your app truly needs it.
Do you build for both Android and iOS?
Yes. Using cross-platform frameworks like Flutter or React Native, we build a single app that runs on both Android and iOS from one codebase, which saves you money and keeps features consistent. When a project specifically needs native performance, we build separately in Kotlin and Swift. We also handle submission to both Google Play and the Apple App Store.
What is an MVP and should I start with one?
An MVP (minimum viable product) is a lean first version with only your core features, built to test the idea with real users before investing in the full app. For most startups it is the smart move — you launch faster, spend less, and learn what users actually want before building the rest. I often recommend an MVP so you avoid spending lakhs on features nobody uses.
Do you help publish the app to Google Play and the App Store?
Yes, we handle the entire submission process — developer account setup guidance, store listing assets, screenshots, descriptions and the technical build requirements for both Google Play and the Apple App Store. App store approval can take a few days, and we manage any review feedback. You own the developer accounts and the app listings, registered in your name.
Kya aap startup ke liye budget mein app bana sakte ho?
Haan. Startups ke liye hum pehle ek MVP banate hain — sirf zaroori features — taaki aap kam budget mein market test kar sako. Simple app ₹80,000 se shuru hoti hai. Budget kam hai to bataiye, main features ko is tarah plan karunga ki aap abhi launch kar sako aur baad mein aur features add kar sako. WhatsApp: 75175 72000.
Will I own the app and its source code?
Yes. You own the source code, the app store listings and the developer accounts — all registered in your name and handed over. We do not lock you into proprietary systems or hold your code hostage. If you ever move to another developer, everything transfers cleanly. That ownership transparency is a core principle of how I run Cyber Defence.
Do you provide maintenance after the app launches?
Yes. Every project includes a warranty period for bug fixes at no extra cost. After that we offer optional maintenance covering OS updates, bug fixes, security patches, server upkeep and new features. Apps need periodic updates as Android and iOS evolve, so ongoing support matters — but it is optional and there is no long lock-in contract.
Is my app and user data secure?
Security is my core expertise — I am CEH and CRTA certified. We build apps with encrypted storage, secure token-based authentication, protected APIs and safe handling of personal data, so user information is not left exposed. Security is designed in from the start, not bolted on later. For apps handling payments or sensitive data, this discipline genuinely matters.
