iOS & Android App Development Company in Mumbai
Beautiful, fast mobile apps your customers keep using — built cross-platform with Flutter and React Native, or native in Swift and Kotlin, and launched on the App Store and Google Play.
UNNI AI Labs builds mobile apps for startups, retailers, real estate developers, restaurants and schools across India. Our Mumbai team covers product strategy, UI/UX, development, backend APIs, store submission and post-launch growth.
We ship our own apps too — Rajyog's waiter and kitchen apps, Shikshalaya's parent app and DigiInfoCard — so we design for real-world usage: patchy networks, low-end Android devices, offline mode and push notifications that bring users back.

FAQs
How much does it cost to develop a mobile app in India?
A cross-platform MVP usually starts from ₹3–6 lakh, while feature-rich apps with custom backends range higher. We provide a fixed quote after scoping your features.
Should I choose Flutter, React Native or native development?
Flutter or React Native suits most business apps and saves 30–40% by sharing one codebase. Native Swift and Kotlin is best for heavy graphics, hardware access or very high performance needs.
Do you publish the app on the App Store and Google Play?
Yes. We handle developer accounts, store listings, compliance reviews and release management for both stores.
Can you maintain and update an existing app?
Yes. We take over existing apps, fix crashes, upgrade SDKs and add new features under a monthly support plan.
