Flutter App Development
Cross-platform mobile apps for iOS and Android built on Flutter. One codebase, near-native performance, consistent UI across platforms. Our primary recommendation for most projects.

Mobile App Development Company in India
Most mobile app development companies in India will quote you a low price and then either miss the deadline, deliver a bloated codebase, or hand you a React Native app they have reskinned from a template. We do not operate that way. Innovatrix Infotech is a DPIIT-recognized startup and mobile app development company with a 12-person engineering team based in Kolkata. We build mobile apps using Flutter as our primary cross-platform framework, with Swift for iOS-native and Kotlin for Android-native when the use case demands it. Flutter is our deliberate choice — one codebase, near-native performance, and a build pipeline that lets us ship faster without cutting corners on UI quality. We have built e-commerce apps, service booking platforms, B2B dashboards, and consumer apps across sectors. For Baby Forest, an Indian D2C baby care brand, our Shopify-connected mobile experience drove ₹4.2 lakh in launch-month revenue and reduced cart abandonment by 22%. For Zevarly, a fashion brand, we improved session duration by 55% and repeat purchase rate by 33%. These are not vanity metrics — they are outcomes from well-engineered mobile experiences. As an AWS Partner, our app backends are hosted on infrastructure that scales. As a Google Partner, we know what Play Store compliance looks like before you submit. Every project runs on a fixed-price, sprint-based model. Scope is defined before sprint one. Payment is tied to sprint milestones, not vague percentage completions. If you are looking for a mobile app development partner in India that will tell you the truth about what your app needs, quote you honestly, and actually ship it — this is the right conversation.
- Ship a production-ready Flutter app for both iOS and Android from a single, maintainable codebase
- Reduce cart abandonment and improve conversion with a mobile-first shopping experience — like the 22% improvement we delivered for Baby Forest
- Drive repeat purchases with an app that users actually return to — like the 33% repeat purchase improvement for Zevarly
- Get fixed-price, milestone-based delivery with no hidden fees or scope creep surprises
- Launch on App Store and Play Store with a team that knows compliance requirements before submission

Service Overview
Everything you need to know about Mobile App Development Company in India
India's mobile-first market is one of the most demanding in the world. Users expect apps to load fast, work offline where needed, and feel native. Building that on a limited budget and a tight timeline requires an engineering team that has done it before.
Innovatrix Infotech builds mobile apps in Flutter for cross-platform delivery and native Swift or Kotlin when platform-specific performance or capabilities require it. We do not recommend React Native. Flutter gives us better performance, a more consistent UI layer across iOS and Android, and a faster build cycle. We back our technology choices with engineering rationale, not vendor relationships.

FloraSoul India
100x Revenue growth over 4 years₹1Cr+ From ₹1L to ₹1Cr+ annual revenue+340% Organic traffic increase (Year 1)1.4s Average page load time
FloraSoul India, an Ayurvedic skincare brand founded by Garima Ahuja and Aankush Nagpal, had a vision to bring traditional Indian wellness wisdom to modern consumers. But their digital journey was anything but smooth. Their original website was built on WordPress by two freelancers who took their money and disappeared midway — leaving behind a broken, unusable storefront. The site suffered from constant downtime, painfully slow page loads, and a checkout experience that actively drove customers away. With practically zero revenue from their online channel and growing frustration, FloraSoul was on the verge of abandoning e-commerce altogether. When they reached out to us, they needed more than just a website. They needed a technology partner they could actually trust — one that would deliver on time, on budget, and stick around after launch.
Case studyBaby Forest
₹3Cr+ Annual revenue milestone1.8s Average page load time4.2% E-commerce conversion rate65% Revenue from mobile shoppers
Baby Forest had already built a loyal following among parents who valued Ayurvedic baby care. But their online storefront wasn't keeping up with the brand's premium positioning. The existing website looked dated, loaded slowly on mobile, and wasn't converting the traffic it was getting. In the premium baby care segment, trust is everything. Parents research extensively before putting anything on their child's skin. Every element of the digital experience — from product photography presentation to ingredient transparency — needs to instil confidence. Baby Forest needed a website as premium as their products: elegant, fast, and built to convert discerning parents into repeat customers. With plans to onboard Mira Rajput as brand ambassador, the stakes were even higher. The website had to handle celebrity-driven traffic spikes without breaking a sweat, and the brand's digital identity had to be polished enough to sit alongside a high-profile endorsement.
Case studyZevarly
+280% Organic traffic growth (6 months)+45% Average order value increase+33% Repeat purchase rate1.6s Average page load time
Zevarly, a Kolkata-based fashion jewellery brand run by Mukesh Sethiya from the heart of Burrabazar, had built a loyal offline following through wholesale channels. But the brand had zero digital presence — no online store, no product catalogue, and no way to reach the growing wave of women shopping for jewellery online. The challenge was significant: fashion jewellery is one of the most competitive e-commerce categories in India. Customers can't touch or try on products, so every element of the online experience — from product photography presentation to zoom-enabled detail views — needs to build trust and desire simultaneously. Zevarly's product range spans hundreds of SKUs across gold-plated, silver-plated, and American Diamond collections, including bridal sets that need to feel premium even through a screen. Their competitors were already established on Shopify with polished stores, influencer partnerships, and strong Instagram presences. Zevarly needed more than just a website — they needed a complete digital commerce strategy that could compete from day one, with smart navigation for a large catalogue and pricing strategies that encouraged bulk purchases.

What our clients say
Honest words from people who've been through the process. No stock photos, no made-up companies.
“When two freelancers ran away with our money, we had lost all trust in agencies. Innovatrix didn't just rebuild our store — they rebuilt our confidence. Four years later, we've gone from one lakh to over one crore in revenue. They're not our vendor, they're our technology partner.”
G
Garima Ahuja
Co-founder, FloraSoul India
“We had jewellery but no digital presence. Innovatrix gave us a Shopify store that actually feels like walking into a jewellery showroom. The tiered discounts and WhatsApp integration alone doubled our repeat customers. We went from zero online orders to processing 50+ orders a day within four months.”
M
Mukesh Sethiya
Founder, Zevarly
“Before this system, our team was glued to their phones all day just answering the same questions over and over. Now those hours are back, and our customers actually get faster responses than when we were doing it manually. Rishabh and his team understood our operations deeply before writing a single line of code.”
