The ceilings
The ceilings founders hit on this layer
Your freelancer disappeared after the app launched
The app went live. Then the developer went quiet. Now crashes are piling up, Play Store reviews are dropping, and nobody owns the codebase. You need a team that stays after launch, not before payment.
Your Shopify store has no mobile app — competitors do
Big D2C brands you compete with have their own apps with push notifications, exclusive offers, and loyalty programs. You're losing repeat purchases to them because Shopify's web checkout is less sticky than a branded app icon on a customer's phone.
You built an MVP on React Native and it's buggy
Scrolling stutters. Animations are janky. Push notifications work on iOS but not Android. Memory usage is bad. The codebase is a tangle of community libraries with no long-term support. You need a fresh architecture, not more patches.
App Store / Play Store rejected your app
App Store rejected it for guideline 4.3 (spam — copycat app). Play Store flagged it for intrusive permissions. Your developer doesn't know what to do. You're stuck in review loops burning weeks.
Your internal team is spending hours on manual work an app would automate
Field staff filling paper forms. Delivery partners calling in for addresses. Sales reps taking orders on WhatsApp. A small internal mobile app would save 20+ hours/week — but nobody has time to build it.
You want to add AI features (chat, image recognition, recommendations) but the app can't handle it
ChatGPT integration would help your users. Image-based product search would delight them. Personalised recommendations would drive repeat purchase. But the existing app's architecture can't plug in LLMs or ML models without a rewrite.
You're quoted ₹50L for a "simple app"
Big agencies quote enterprise prices. You don't need enterprise — you need a well-built app under ₹15L that can scale. Finding a team that hits that price without being a freelancer roulette is hard.
Your app has no tracking — you're shipping blind
User behaviour isn't instrumented. Crashes aren't monitored. Funnel drop-offs are invisible. You're making product decisions on App Store reviews and gut feel. You need Mixpanel / Amplitude / Sentry wired correctly from day one.
What we build for you
Here's what changes once we're done.
React Native Apps
React Native with TypeScript. Chosen when your team already has React web expertise — code sharing with a Next.js front-end is meaningful. Expo SDK for faster iteration; ejection to bare workflow when you need native modules.
Native iOS (Swift)
Swift 6 + SwiftUI + iOS 17/18. Chosen for apps with deep Apple ecosystem integration (WidgetKit, App Intents, Siri, HealthKit, HomeKit, CarPlay, Apple Watch companions, ARKit).
Native Android (Kotlin)
Kotlin + Jetpack Compose + Material 3. Chosen for apps with Android-specific features (WearOS, Android Auto, widgets, background services) or when Android-only makes sense for your market.
Shopify Mobile Apps
Flutter app connected to Shopify Storefront API. Synced inventory, products, orders, customer accounts. Push notifications for order updates + flash sales. Deep-linked product URLs from Meta Ads. Standard for scaled D2C brands.
SaaS Product Apps
Companion apps for B2B SaaS products — dashboards, notifications, quick actions. Auth synced with your web app, offline capability for field use, enterprise distribution if needed.
Delivery + Logistics Apps
Driver apps, warehouse scanner apps, field service apps. Offline-first, real-time location, barcode / QR scanning, sync queue for low-connectivity areas.
Booking + Service Apps
Salon, clinic, consultancy booking apps. Calendar sync, payment deposits, WhatsApp / SMS reminders, review collection.
Community + Social Apps
Member communities, interest-based feeds, direct messaging, content posting. Firebase / Supabase backend for real-time sync; moderation tools for admin.
AI-Powered Mobile Apps
OpenAI / Claude / Gemini chat, on-device ML (Core ML, ML Kit) for vision / translation, image-based product search, personalised recommendations. Careful scoping — not every feature benefits from LLMs.

What clients say
“Switching to a dedicated website was the best decision for my business, especially after the struggle of managing endless manual inquiries on social media.”
The team at Growww Ecommerce took my vision and turned it into a professional reality in just one week, handling everything from payment gateways to shipping integrations. Their guidance on advertising and backend setup has been invaluable, and I only wish I had partnered with them sooner.

FAQ
Commonly asked
Yes. Our Gurgaon clients collaborate remotely via weekly TestFlight / Firebase App Distribution builds, async code reviews, and shared Slack / WhatsApp channels. Remote delivery ships faster than in-person meetings for mobile; quarterly in-person reviews available.
Post-launch accountability (most local agencies vanish after the App Store approval email), Flutter-first stack with honest native recommendations when it matters, fixed-price billing, and 98% first-try App Store approval. Senior engineers, not offshore juniors.
Yes — Flutter 3.x with tight performance tuning (sub-1-second cold start, 60/120fps scrolling, <50MB memory footprint), crash-free rate >99.9%, proper code splitting. Native Swift / Kotlin for apps where Flutter's performance ceiling isn't enough.
Not from day 1 — Gurgaon SaaS usually validates product-market fit on web first, adds mobile-companion once weekly active users justify it. We advise honestly when mobile is worth the investment vs when it's early.
Flutter for 80% of projects — one codebase, iOS + Android, near-native performance, mature ecosystem. React Native if your team is already deep in JavaScript / React web code and prefers code-sharing. Native Swift (iOS) + Kotlin (Android) when you need platform-specific features like AR (ARKit / ARCore), WearOS, CarPlay, or the latest OS APIs. We'll recommend the right fit in the first call, not sell you the one we prefer.
Flutter app (cross-platform, standard features): ₹4,00,000–₹8,00,000. React Native app: similar range. Native iOS + Android (two codebases): ₹8,00,000–₹15,00,000 — roughly 2x Flutter. Complex apps with backend (marketplaces, multi-tenant SaaS, AI integrations): ₹10,00,000–₹40,00,000. All fixed-price with milestone billing — no hourly billing balloons.
Simple Flutter app (MVP, 3-5 core features, backend integration): 6-8 weeks. Standard app (auth, profiles, product / content feed, push): 8-12 weeks. Complex app (custom backend, payments, offline sync, AI features): 14-20 weeks. App Store review adds 1-3 days (Apple) or hours (Google). Total: scope to live in the stores.
Yes — this is one of our most common asks. Flutter app + Shopify Storefront API + synced inventory / products / orders. Push notifications for order updates, abandoned carts, flash sales. Deep-linked product URLs so Meta Ads / Google Ads click straight into app product pages. Standard build ₹4,00,000 fixed.
98% of our apps clear review on the first submission. We know the common rejection reasons (guideline 4.3 spam, 5.1.1 privacy, intrusive permissions, metadata issues) and design around them from scoping. Apps that fail review usually have vague descriptions, missing privacy policies, or overbroad permissions — we handle all three as part of submission prep.
Yes — OpenAI / Claude / Gemini chat, vision models for image-based product search, on-device ML (Core ML on iOS, ML Kit on Android) for real-time features. LangChain / custom backends for RAG pipelines. We scope AI carefully — not every feature justifies LLMs; we advise on which features are worth the complexity cost.
Yes. 30 days of bug-fix support included. Retainers from ₹30,000/month cover: iOS + Android OS updates (annual compatibility work), new feature shipping, analytics dashboards, App Store review responses, and performance monitoring. Or you take it in-house — we hand over complete code, documentation, signing credentials, and store access. No vendor lock-in.
You do. From day one. Complete source code, App Store Connect access, Play Console access, signing certificates, and backend credentials all belong to you. Standard practice. We sign an IP-assignment clause in every contract — no hostage apps.
Yes. Field service apps, sales force apps, delivery partner apps, inventory scanning apps — all routine for us. Internal apps distributed via enterprise program (Apple Developer Enterprise) or MDM (Jamf, MobileIron, Intune) instead of public stores. Typical timeline: 6-10 weeks, fixed-price from ₹5,00,000.
We wire Mixpanel or Amplitude for product analytics (funnels, cohort retention, feature adoption), Firebase Analytics / GA4 for marketing attribution, Sentry / Firebase Crashlytics for crash reporting. Dashboard access handed over at launch — you see real numbers, not vague "the app is doing well."
We don't build games (different discipline — Unity / Unreal specialists handle those better). AR features on top of a consumer app (product try-on, store-finder AR overlays) — yes, via ARCore / ARKit, scoped as a feature within a larger app build. Full VR apps — no, not our specialty.
For 90% of use cases — yes. Flutter's rendering engine is native-performant, animations run at 60/120fps, memory usage is competitive. The 10% where native wins: apps deeply integrated with OS-level features (WearOS companion apps, CarPlay, Siri shortcuts, HomeKit), or apps that need the absolute lowest battery usage (fitness trackers always-on). We advise honestly which bucket your project falls into.
Local SQLite / Hive database for offline storage, sync queue that retries when connectivity returns, conflict resolution for concurrent edits. Used on delivery / field-service apps where partners work in low-connectivity areas. Standard pattern in our Flutter builds; adds 2-3 weeks to scope.
Three reasons: (1) Fixed-price, not hourly — big services firms bill hourly and projects balloon 2-3x; freelancers disappear. (2) Senior team — your project gets 2-3 senior engineers, not 10 juniors. (3) Post-launch accountability — we ship, monitor, and stay. Most freelancers vanish after the App Store approval email.
