From a web checkout to an app icon on their phone.
Your repeat customers re-find you through ads they already paid for — the brands they open daily live on the home screen. This build ships one Flutter codebase to both stores, synced to your Shopify catalogue, with push notifications that bring buyers back on 90-day cycles. ₹4,00,000 + GST fixed, live in 6–8 weeks, full code ownership. 50+ apps shipped, 98% clear store review on the first try.
From re-buying the same customer to reaching them for free.
Before
Your repeat customers re-find you through ads you already paid for once — every reorder quietly costs you acquisition budget a second time.
After
An app icon on their phone and a push channel you own — you bring repeat buyers back without re-buying the click, so ad spend goes to winning new customers, not re-winning old ones.
Acquisition is the expensive part of every order; an owned push channel re-engages buyers you've already won at near-zero marginal cost. It earns its ₹4,00,000 once you're past roughly 1000 orders/month with buyers who reorder inside 90 days — food, beauty, wellness, pet care. Quarterly, high-AOV categories should skip it.
One codebase. ₹4,00,000. Both stores.

The Growww Guarantee: On time, or it's on us.
Fixed written scope in 48 hours — extras are named and priced there, never mid-build. 200+stores shipped — we've never missed a timeline. How it works →
You're not failing — the web checkout is at its ceiling.
Six ceilings brands hit before they buy an app. If two or more read like your week, this build is for you.
Competitors' apps are stealing your repeats
Big D2C brands have push notifications, exclusive drops, and an icon on the customer's phone. A web checkout is less sticky than an app — and repeat purchases follow stickiness.
Your freelancer vanished after launch
The app went live, the developer went quiet, crashes are piling up, and nobody owns the codebase. You need a team that stays after launch, not before payment.
Your MVP is buggy and unfixable
Stuttering scrolls, janky animations, push that works on one platform only. A tangle of unsupported libraries needs a fresh architecture, not more patches.
Stuck in store-review loops
Guideline 4.3, privacy flags, permission rejections — weeks burning while your developer guesses. 98% of our apps clear review on the first submission.
Quoted ₹50L for a simple app
Big agencies quote enterprise prices for a standard build. You need a well-built app at a fixed price that can scale — not freelancer roulette either.
You're shipping blind
No crash monitoring, no funnels, no cohort retention. Product decisions run on App Store reviews and gut feel. Analytics belongs at launch, not later.
Three ways to build. We recommend the fit, not the favourite.
This proposal prices the Flutter build — the right call for 80% of projects. The other two exist for specific reasons, and we'll say honestly which bucket yours falls into.
Flutter
The default for 80% of projects — one codebase, iOS + Android, 60–120fps animations, near-native performance, roughly 40% cheaper than building native twice. This proposal's build.
React Native
When your team is already deep in JavaScript / React — code-sharing with a Next.js web app is meaningful. Similar price range to Flutter; we scope it on the call.
Native Swift / Kotlin
When platform-exclusive features are the point: ARKit, WearOS, CarPlay, HealthKit, widgets. Two codebases — ₹8,00,000–₹15,00,000, roughly 2x Flutter. We'll say honestly if you need it.
Discovery to both stores — 6–8 weeks.

When you should not buy this.
Below roughly 1000 orders/month, don't. An app icon won't fix repeat rate at that volume — the store and the funnel will. The same budget on the ₹50,000 store build plus the ₹75,000 CRO pass returns more.
An app earns its ₹4,00,000 when your customers reorder within 90 days — food, beauty, pet care, wellness. Push notifications compound on short repurchase cycles. If your buyers purchase quarterly at high AOV (apparel, gifting, home decor), skip the app and double down on the mobile web store — we'll tell you that on the discovery call.
How the 6–8 weeks run — milestone by milestone.
Complete transparency. Seven milestones from discovery to launch, each with what we ship and what you receive.
- Milestone 01Week 1
Discovery + Scope
A 30-minute call on the app's purpose, audience, and business model — then a fixed scope in writing within 48 hours.
- Below roughly 1000 orders/month, we'll usually tell you an app won't fix repeat rate yet — spend the budget on the store and CRO first.
- The scope document covers features, the tech-stack recommendation, milestones, and the fixed price — no hourly billing balloons.
- You get access to our client portal at portal.growwwtech.com for feedback, approvals, and progress tracking.
You'll receive
- Straight fit verdict on the call
- Fixed written scope within 48 hours
- Client portal access
- Milestone 02Weeks 1–2
Design in Figma
Wireframes and user flow first, then high-fidelity Figma mockups for the key screens. Design approval before code starts.
- Two rounds of consolidated feedback via the portal.
- Designed on real platform constraints — what iOS and Android actually allow — so the build matches the file.
You'll receive
- Wireframes + user flow
- High-fidelity Figma mockups
- Design sign-off before code
- Milestone 03Weeks 2–6
Build in Sprints
One Flutter codebase, both platforms — 2-week sprints with weekly demo builds on your own phone.
- Weekly builds distributed via TestFlight (iOS) and Firebase App Distribution (Android) — you test on real devices every week and flag issues early.
- Flutter is the default for 80% of projects: one codebase, near-native performance, roughly 40% cheaper than building native twice.
You'll receive
- Weekly TestFlight / Firebase builds
- One Flutter codebase — iOS + Android
- Milestone 04Inside the sprints
Backend + Integrations
Shopify Storefront API sync, push, deep linking, payments, and analytics — wired in as feature branches merge, not bolted on at the end.
- Products, inventory, orders, and customer accounts synced from your Shopify store in real time.
- Push notifications (OneSignal / Firebase) for order updates, abandoned carts, and flash sales; deep-linked product URLs so Meta Ads click straight into app product pages.
- Crash reporting (Sentry / Crashlytics) and product analytics (Mixpanel / GA4) instrumented from day one — you ship with eyes open, not blind.
You'll receive
- Shopify Storefront API integration
- Push + deep linking wired
- Crash reporting + analytics dashboards
- Milestone 05Weeks 6–8
Store Submission
App Store and Play Store submission handled end-to-end — 98% of our apps clear review on the first try.
- Metadata, screenshots, keywords, privacy policy, and data-safety forms prepared for both stores.
- The common rejection traps (guideline 4.3 spam, 5.1.1 privacy, overbroad permissions) are designed around from scoping, not patched in review loops.
You'll receive
- Both store submissions handled
- Store assets: screenshots, descriptions, icons
- Fast response to any review notes
- Milestone 06Week 8
Launch + 30-Day Support
Public launch on both stores, then 30 days of bug-fix support included. You own everything.
- Complete source code, App Store Connect and Play Console access, signing certificates — all yours from day one, IP-assignment in the contract.
- Optional retainer from ₹30,000/month for OS updates, new features, and store-review management. Or take it in-house — the handover is written for your team.
You'll receive
- Live on App Store + Play Store
- 30-day bug-fix support
- Full code + store access handover
- Milestone 07
Out-of-Scope Work Policy
Any request beyond the fixed written scope is out-of-scope work — handled transparently, never silently billed.
- Custom marketplace backends, offline-first field-service patterns, and AI features are scoped and priced separately — named before kickoff.
- Smaller extras are tracked in the Growww Tech client portal and billed only with your approval.
You'll receive
- Transparent time tracking via portal
- Prior intimation before any additional billing
What we need from you. What we don't do.
No surprises post-kickoff. Here is the assumption boundary on both sides.
What we need from you
- Apple Developer ($99/yr) and Google Play ($25 one-time) accounts — registered in your name; we handle everything inside them
- Logo and brand assets — identity creation is a separate service
- Access to your Shopify store (or backend API) for the integration
- Product photography — the app renders your real catalogue
- A decision-maker on the weekly build review
- Consolidated design feedback within 3 working days per round
What's not included
- Games and full VR apps — different discipline; AR features inside a consumer app are scoped separately
- Custom marketplace / multi-tenant backends — scoped and priced separately (₹10,00,000–₹40,00,000 territory per the cost FAQ)
- AI features (LLM chat, image search, recommendations) — scoped separately; we'll say which ones justify the complexity
- Logo and brand-identity design — that's Brand Foundations, priced separately
- Copywriting, product photography, and video
- Store fees and subscriptions — Apple/Google accounts, Firebase overages, push volumes are billed to you directly
- Ongoing development after the 30-day support window — optional retainer from ₹30,000/month
One team, every rung. Buy the one your money is leaking from.
Every rung pulls more orders out of traffic you already pay for. You don't climb it in order — you start where the leak is. Here's the honest map.
| Upgrade | Price | Best when | What changes |
|---|---|---|---|
| Shopify Store | ₹50,000+ GST | You're selling in DMs or on a stock template — your first real store. | Off the DMs onto a store on our own theme — payments, shipping, GST, live in 4 weeks. |
| CRO Pass | ₹75,000+ GST | You already have traffic, but it leaks at the cart and the checkout. | 344 checks implemented on your live store — plug the ~70% cart-abandon and COD-RTO leaks. More orders from the same ad spend. |
| UI/UX Design | ₹1,50,000+ GST | The store works but looks like everyone's template — you want a custom, phone-first design. | All 15 store templates drawn phone-first for your brand, with a design system your team keeps. Design only — the build is separate. |
| Headless Next.js | ₹4,00,000+ GST | Roughly ₹50L+/month and the theme is capping your speed, design, or SEO. | A storefront you own, built to beat Google's 2.5s LCP bar — where a 0.1s speed gain is tied to +8.4% conversion. |
| Enterprise Bundle | ₹5,00,000+ GST | ₹2Cr+/month, and you want store, design, speed and funnel rebuilt together — one team. | Headless + store + UI/UX + CRO folded in — about ₹6,75,000 of work for ₹5,00,000. |
| Mobile AppYou’re here | ₹4,00,000+ GST | Roughly 1000+ orders/month and buyers who reorder inside 90 days. | An owned home-screen channel — reach repeat buyers by push instead of re-buying the ad. Repeat orders up, re-acquisition spend down. |
Our recommendation: plug the leak before you widen the pipe. A CRO pass earns its fee on traffic you already have; headless and an app pay off only once speed or repeat-rate is the actual ceiling. If a cheaper rung returns more for you right now, we’ll say so on the call rather than sell you the bigger number.
