Mobile App Development for Startups: A Complete Guide to Launching on a Budget
Most startup MVPs in India cost somewhere between ₹3 lakh and ₹15 lakh to build, a fraction of what the same scope typically costs with a US-based team, and…















Native Android apps in Kotlin, built to run smoothly on the phones your customers use, including budget devices.
Native iOS apps in Swift, built to Apple's guidelines for a smooth App Store review, secure and ready to scale.
Flutter, React Native and hybrid apps for Android and iOS from a single codebase: one team, lower cost.
Feature-rich shopping apps that boost customer engagement and online sales.
Platforms we build for
ICore is an app development company in Coimbatore that builds native, hybrid and cross-platform apps. Here is when each platform is the right choice.
Native Android apps in Kotlin, tested on the budget phones most Indian customers use, not just flagship emulators, and published on Google Play. Android runs on about 95% of smartphones in India (StatCounter), so for a consumer app it usually comes first.
Native iOS apps in Swift, built to Apple’s guidelines so the App Store review goes smoothly: privacy disclosures, permission texts and review flows are in place from day one.
Flutter ships one codebase to both Android and iOS with very consistent UI and performance, at a lower cost than two native builds. It is our default for most business apps.
React Native also builds Android and iOS from one codebase. It fits best when your team already works in JavaScript or React, or when the app shares code with a React website.
A typical app with 5 to 8 screens, login and a backend API takes 10 to 16 weeks from start to store launch. Bigger apps add development time; the stages stay the same.
About 1 week
We agree screens, features and integrations in writing, so the price and timeline are fixed before development starts.
2–3 weeks
Wireframes, then the visual design for every screen, approved by you before any code is written.
5–8 weeks
App, backend API and integrations (payments, login, notifications), shown to you in working builds as we go.
1–3 weeks
Tested on real devices, including low-spec Android phones, plus a fix round from your own review.
About 1 week
We handle Google Play and App Store submission and respond to any reviewer questions.
30 days included
Bug fixes and help after launch; ongoing maintenance is available afterwards.
Apps rejected for incomplete privacy disclosures, missing permission descriptions, or broken review flows cost weeks of delay. We build to Apple and Google review guidelines from day one.
India’s mobile market includes many budget phones with 2GB RAM. We test on real low-spec devices, not just flagship emulators, so performance holds across the market.
An app without in-app purchase, subscription billing, or Razorpay/Stripe integration misses revenue. We plan these from the spec stage, not bolt them on at the end.
Material 3 on Android and Apple’s Human Interface Guidelines on iOS are the current standards. Users notice when an app feels a design cycle behind.
An app that works with 100 users may fail at 10,000. We architect the backend API for the user volume you plan to reach in 12 months, not just what you have today.
Payment gateways, WhatsApp Business, push notifications, and mapping APIs all have API quirks. We have integrated all of them across previous builds and know where the edge cases are.

Flutter delivers Material 3 on Android and Cupertino components on iOS from one codebase. Both platforms feel native, not like a web wrapper.
We test on a range of real Android and iOS hardware including popular low-end devices in the Indian market, not just flagship emulators.
We prepare all screenshots, metadata, and privacy disclosures and submit to both stores. A clean first submission significantly reduces delays and rejection risk.
REST API or GraphQL backend with authentication, rate limiting, and horizontal scaling — ready for the user growth you plan for in the next 12 months.
Thirty days of post-launch bug fixes are included as standard. Monthly support plans for ongoing updates and new features are also available.

ICore mobile apps start from ₹3 lakh. A focused app with login, a content feed, and notifications typically costs ₹3,00,000 to ₹6,00,000 for a Flutter cross-platform build covering both Android and iOS. A native-only build for the same scope costs 30 to 40% more. Apps with real-time features, payments, GPS, or a complex backend are scoped individually. We give a fixed price for defined scope.
An app with 5 to 8 screens, login, and a backend API takes 10 to 16 weeks. More screens, third-party integrations, and payment flows add to that. We run a discovery sprint at the start to lock scope before development begins.
