Flutter app development
Flutter app development for Android and iOS from one codebase.
Flutter is our default for mobile apps. One codebase ships to Android and iOS with the same interface and performance close to native, which is why we use it for consumer platforms like delivery, matrimony and astrology apps, and for field apps used by riders, technicians and sales teams. Built in Coimbatore for clients across India and abroad.
- ₹4L+Flutter app
- 1codebase, 2 platforms
- 10–16weeks typical
- Razorpayand UPI built in
Direct answer
What is Flutter, and why do we use it?
Flutter is Google's open-source toolkit for building Android and iOS apps from a single codebase, compiled to native code. SpikeSecure uses Flutter for most new mobile apps because it halves the cost of maintaining two native apps, gives a consistent interface on both platforms and performs well on the mid-range Android phones most Indian users own. Flutter apps at SpikeSecure start at ₹4 lakh and take 10–16 weeks to reach both stores; our Local Friends calling app is a single Flutter binary with a Talk and Earn mode toggle.
Choose Flutter for consumer apps, marketplace and on-demand platforms, field-service and sales apps, and customer apps for existing businesses. Choose native Swift and Kotlin only for hardware-heavy or platform-specific products, and React Native when a React-based team will maintain the app.
- Built with Flutter at SpikeSecure: the Local Friends anonymous calling app, and our delivery, booking, matrimony, astrology and field-service app platforms.
- Typical cost: simple app ₹4–8 lakh; on-demand or marketplace MVP ₹5–12 lakh; full platform ₹10–25 lakh.
- Typical timeline: 10–16 weeks to both stores, including store submission and review.
- Pairs with: NestJS or Node.js APIs, PostgreSQL, Firebase for push and analytics, Razorpay and UPI, Agora for calls, Google Maps.

Flutter versus the alternatives
Honest trade-offs before you choose.
- Flutter versus native (Swift and Kotlin). Native wins on deep hardware access and platform-specific UI; Flutter wins on cost, speed and consistency. For most business and consumer apps the difference in user experience is not noticeable, and the difference in cost is.
- Flutter versus React Native. Both are cross-platform and mature. Flutter gives more consistent rendering and fewer native-module surprises; React Native suits teams already fluent in React. We recommend by who will maintain the app.
- Flutter for web and desktop. Possible, but we build web front ends in Next.js or React because they are better for SEO and browser behaviour; Flutter stays on mobile.
- App size and startup. Flutter apps are larger than minimal native apps; we manage this with asset optimisation and deferred loading, and measure startup on mid-range devices.
- Payments in India. Razorpay, UPI intents, Paytm and wallet flows are well supported; we have production integrations for all of them.

How we work
How a Flutter app project runs, step by step.
The same six steps run on every project we take in Coimbatore, whether it is a five-page website or a multi-vendor platform.
01
Discovery — week 1
We listen, audit what exists and write down what success looks like in numbers, then send a fixed-scope written quote, usually within 48 hours.
02
Design — weeks 2–3
Wireframes, design system and a clickable prototype. You see every screen before a line of code is written.
03
Build — week 3 onwards
Weekly demo on a staging URL and GitHub access from day one, so you are never wondering where the project is.
04
Test — final 1–2 weeks
Functional, performance, accessibility and security testing against a pre-launch checklist signed off in writing.
05
Launch — launch week
DNS, monitoring, analytics and backups configured; we watch the first 72 hours with you.
06
Support — ongoing
30-day warranty on every build, then optional SLA-backed maintenance with a monthly health report.
FAQ
Questions about Flutter development.
Is Flutter good enough for a serious consumer app?
Yes. Flutter compiles to native code and renders its own UI, giving smooth performance on both platforms. We use it for apps with live tracking, video calls and payments, including our own Local Friends product.
How much does a Flutter app cost in India?
At SpikeSecure, simple apps cost ₹4–8 lakh, on-demand and marketplace MVPs ₹5–12 lakh and full platforms ₹10–25 lakh. One codebase for Android and iOS is the main saving compared with two native apps.
Flutter or React Native?
Flutter by default for consistency and performance; React Native when your in-house team is React-based and will maintain the app. Both are fine choices; the wrong choice is native twice on a limited budget.
Does Flutter support UPI and Razorpay?
Yes. We have production integrations for Razorpay, UPI intent flows, cards, wallets and cash on delivery, plus RazorpayX for partner payouts.
Do you handle App Store and Play Store submission?
Yes. Store listings, screenshots, privacy declarations, review responses and release management are part of every app project, with the store accounts in your name.
Can you provide dedicated Flutter developers?
Yes. Dedicated Flutter developers and teams for Indian and international clients; see the hire developers in India page.
