SpikeSecure Technologies Pvt. Ltd. is a mobile app development company in India, based at CHIL SEZ IT Park, Saravanampatti, Coimbatore, Tamil Nadu, building iOS and Android apps for startups, retailers, service businesses and enterprises across the country. We build in Flutter by default, in React Native when your team already writes React, and natively in Swift and Kotlin when the app depends on the camera, AR or Bluetooth, and we wire in what Indian apps need on day one: UPI, Razorpay and Cashfree payments, OTP login, maps, WhatsApp and push notifications, and Tamil, Hindi and other Indian-language interfaces.
Choose SpikeSecure if you want a fixed price for a written scope, a test build on your phone every sprint, and an app, code and store accounts that are yours from the first day. We publish our price ranges, run our own app in production (Local Friends) and name client work only with permission. We do not call ourselves the best or the top company in India; the evidence section below is what we can show.
The same published ranges as our Coimbatore page, so the price does not change with your city. Indicative, confirmed in a fixed-scope written quote after discovery.
Catalogue, booking or information app with login, push notifications and a basic admin, built once in Flutter or React Native for iOS and Android. 6–10 weeks.
Backend and APIs, Razorpay or UPI payments, chat, maps, analytics and a role-based admin console. 10–14 weeks, with TestFlight and Play internal testing builds from the first sprint.
Two-sided marketplaces and on-demand apps with dispatch, per-minute billing, KYC, payouts and infrastructure for scale. 12–18 weeks; priced after technical discovery.
How many apps you need on day one (customer, partner, admin), real-time features such as live tracking or video, payments and partner payouts, verification and moderation, and native versus cross-platform.
Cloud hosting of ₹5,000–50,000 a month depending on scale, maps and SMS APIs, per-minute video charges where used, payment gateway fees, and the Apple (US$99 a year) and Google (US$25 once) developer accounts, all billed by those providers.
OS and SDK updates, store-policy changes, security patching, crash monitoring and small features. Optional; every app ships with a 30-day post-launch warranty.
Worked examples and a line-by-line breakdown: mobile app development cost guide.
| Flutter | React Native | Native (Swift and Kotlin) | |
|---|---|---|---|
| Codebases | One for iOS and Android | One for iOS and Android | Two, one per platform |
| Best for | Consumer, booking, delivery and field apps; our default | Teams with React web code to share | Camera, AR, Bluetooth, widgets and heavy graphics |
| Cost compared with native | Usually 40–50% lower | Usually 40–50% lower | Highest |
| What we have shipped on it | QuickBite apps, Local Friends | Client apps on request | Native modules inside Flutter apps |
Short answer: Flutter for most Indian business apps, because one codebase covers both stores and the budget goes on features. React Native when your web team already writes React. Native Swift and Kotlin when the app lives on the camera, AR or Bluetooth. We put the choice and the trade-offs in the written quote. More detail: Flutter app development.

Flutter for most business apps, because one codebase covers iOS and Android and usually costs 40–50% less than two separate native apps (the figure in our cost guide). React Native when your web team writes React. Native Swift and Kotlin when the app depends on the camera, AR or Bluetooth. The recommendation and the trade-offs are written into the quote.
Yes. We prepare the listings, screenshots and privacy forms and submit under your own Apple and Google developer accounts, so the app, the reviews and the download history belong to you.

A 30-day warranty covers defects, then maintenance is optional from ₹15,000 a month for OS and SDK updates, store-policy changes, security patches and small features. The code, store accounts and cloud accounts stay in your name.
