How to start
Tell us what you need in your own words. You talk to the developers who would build it and get a written, line-item estimate.
Get a project estimateIs an app worth it alongside your website?
For a first purchase, most customers are happy on a mobile website. An app pays back when products are bought again and again, because it removes friction from every repeat order and gives you a direct notification channel.
So our e-commerce app development starts with your repeat-purchase pattern. A grocery or beauty brand might lead with buy-again lists and reorder reminders; a fashion label with new-drop alerts and wishlists. The first release stays lean enough to ship quickly, with the rest planned for later versions.
Challenges
Why shoppers uninstall
Too big for the phone
On low-storage Android phones, large apps are the first to be deleted.
Blank screens on weak signal
Apps that fetch everything at launch show spinners on congested networks; cached catalogues keep them usable.
Payments stuck in limbo
Returning from a UPI app can leave an order pending unless the app confirms status with the gateway.
Notification fatigue
Daily blanket promotions get notifications switched off.

How it works
How a repeat purchase happens in a shopping app
Repeat orders are where an app pays for itself, so the whole loop is designed to take as few taps as possible.
- Push notification
Step 1: A timely nudge arrives
A back-in-stock alert or a reorder reminder timed to the product’s usual cycle, sent only to people who opted in.
- App for Android or iOS
Step 2: A deep link opens the right screen
Tapping lands on the exact product or buy-again list, even from WhatsApp or an ad, instead of dumping the shopper on the home screen.
- Customer
Step 3: The basket is built in a few taps
Past orders, saved sizes and a cached catalogue make adding items quick, even on a weak signal.
- Payment SDK
Step 4: One-tap UPI checkout
The app hands over to the customer’s UPI app and, on return, checks the payment status with the gateway so no order is left pending.
- Customer app
Step 5: The order is tracked in the app
Status updates arrive as notifications the customer chose, with the invoice and a return option in the same place.
- Admin dashboard
Step 6: Your team tunes what works
Home-screen sections, offers and notification schedules change without an app release, and opt-out reports show what to dial back.
Then it starts again at step 1: A timely nudge arrives

Plain-English glossary
Shopping app terms, in plain English
- Cross-platform codebase
- One set of code, written in Flutter or React Native, that produces the app for both Android and iOS. It usually costs less than two native apps and keeps features in step on both phones.
- Deep link
- A link that opens a specific screen inside the app, such as one product or a cart, instead of the home page. Deferred deep links even work for people who install the app after tapping.
- Server-driven home screen
- The home screen’s sections and banners are described by your backend rather than fixed inside the app. Merchandisers can rearrange it for a sale without waiting for an app store review.
- Feature flag
- A switch that turns a feature on or off, or on for some users only, without releasing a new version. It lets you try a new checkout with a tenth of shoppers before everyone gets it.
- Card tokenisation
- Replacing a customer’s card number with a token issued through the card network, as RBI rules require. Shoppers can save cards for quick checkout while neither you nor we store the actual number.

Screens in your shopping app
Illustrative screens, using a beauty and personal care app as the example.
Customer app. Repeat customers reorder from past baskets in a few taps, with price drops shown and out-of-stock items clearly marked. 
Customer app. The cart remembers addresses and payment preferences, shows the delivery date and applies app-only offers automatically. 
Customer app. Order updates appear in the app and as notifications the customer opted into, with the invoice and a return option in one place. 
Admin dashboard. Your team rearranges home sections, schedules notifications with frequency caps and prompts old app versions to update, all without a release.

Frequently asked questions
Flutter or React Native for a shopping app?
Both work well for e-commerce. Flutter draws its own UI, which keeps screens consistent on older Android phones and makes custom animation straightforward. React Native uses native components and suits teams already working in React or TypeScript, including sharing logic with a React website. We choose based on your existing code, planned features and who will maintain the app, and explain the trade-off first.
Can you build an app for our existing Shopify or WooCommerce store?
Yes. Shopify offers a Storefront API and WooCommerce a REST API, so the app can read products and create orders on your current store while you keep managing it in its admin. Features such as custom checkout rules or loyalty depend on what the platform and its apps allow. We check those limits during scoping and add a small middleware service where the APIs fall short.
Do Google Play or the App Store take a commission on physical products?
For physical goods, generally no. Both stores' policies place physical products and real-world services outside their in-app billing systems, so you collect payment through your own gateway with UPI, cards or COD. Digital goods, such as paid content inside the app, follow different rules. Store policies change, so we review the current terms during release planning.
How do we keep push notifications useful rather than annoying?
Tie them to events and segments rather than a daily blast. Back-in-stock alerts, price drops on wishlisted items, order updates and reorder reminders timed to a product's usual repurchase cycle tend to be welcome. We build notification categories customers can switch off individually, frequency caps and quiet hours, and report opt-outs by campaign so your team can see what wears the channel down.
