Mobile App Developers in Chennai

SpikeSecure Technologies Pvt. Ltd. is a mobile app development company based at CHIL SEZ IT Park, Saravanampatti, Coimbatore, that builds iOS and Android apps for businesses in Chennai. Chennai projects run on the same written scope, two-week sprints with a test build on your phone, and launch checklist as our Coimbatore work, plus an on-site kick-off and a launch visit in Chennai when the project needs them. Discovery, prototype reviews and sprint demos happen on video calls.

We are stating this plainly: we have one office, in Coimbatore, about 500 km from Chennai, and no branch in Chennai. If you need developers in your office every day, we are not that. If you want a fixed price for a written scope, UPI and Razorpay payments, Tamil and English interfaces and an app you own, we are.

• Typical budget: ₹8–15 lakh for a mid-complexity app: iOS and Android from one Flutter codebase with a backend, payments, chat or maps and an admin console, built in 10–14 weeks.
• Indicative cost: Simple apps ₹4–8 lakh; mid-complexity apps ₹8–15 lakh; platforms ₹15–30 lakh and up. The same published ranges as Coimbatore; travel for on-site visits is itemised in the quote. The final price depends on the approved scope.
• Typical timeline: 6–10 weeks for a simple app or MVP, 10–14 weeks for a mid-complexity app, 12–18 weeks for a platform.
• How Chennai projects run: Discovery call, written quote within 48 hours, on-site kick-off in Chennai where useful, sprint demos and test builds every two weeks, a launch visit for go-live and staff training, and a 30-day warranty.
• Chennai-specific builds: Tamil and English interfaces, delivery and service zones by Chennai pincode, field-staff and dealer apps for manufacturers in Ambattur, Guindy, Sriperumbudur and Oragadam, and booking and loyalty apps for retail and food businesses.

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.

• Discovery. A video call, or a visit to your office in Chennai for larger projects, followed by a fixed-scope written quote within 48 hours.
• Prototype and build. Prototype review on a call; a TestFlight and Play internal testing build at the end of every two-week sprint; a written status note every week; GitHub access from day one.
• Launch. We come to Chennai for go-live and staff training where the project needs it, for example when field staff or store teams start using the app.
• After launch. 30-day warranty, then optional maintenance from ₹15,000 a month; the code, store accounts and cloud accounts are in your name, so you can change vendor without asking us.
• Office. Rajalakshmi Sai Complex, near Sankara College, CHIL SEZ IT Park, Saravanampatti, Coimbatore 641035. Monday to Saturday, 9:30 am to 6:30 pm IST (map). We schedule Chennai visits in blocks and say so in the quote.

• QuickBite (food delivery platform). Delivered: a customer app, a restaurant console and a rider app with automated dispatch, live order tracking and cash-on-delivery reconciliation. Outcome, as reported by the client: from a Figma file to live on the App Store and Play Store in 11 weeks, on budget, with every weekly demo on time.
• Local Friends (SpikeSecure's own product). A single Flutter app with Agora audio and video calls, a per-minute wallet from ₹4 per minute, live rooms and a six-language interface, built and run by our team in production. It is where we test the real-time, payments and moderation work we sell.

Neither is a Chennai business; we do not yet publish a named Chennai client and will add one only with written permission.

Client outcome figures are the client's own, quoted with permission; we do not audit them. All six published case studies are on the work page, and we add new ones only with written permission.
