Mobile Commerce
Shopping apps that work hand in hand with your web store
We build iPhone and Android apps that share your products, cart, and customer accounts with your website, so shoppers can start on one and finish on the other.
In plain English
What is it, in plain English
A mobile commerce app is a shopping app for phones. Customers download it from the Apple App Store or Google Play and buy from you right on their phone.
Think of it as a second front door to the same store. Whether a customer walks in through your website or your app, they see the same shelves, the same prices, and the same shopping basket. If they add something on their laptop, it is waiting in their app later.
How it works
How it works
- 01
Your store stays the single source of truth
Products, prices, stock, and orders still live in your existing store system.
- 02
The app connects to it
We link the app to your store so it reads the same catalog and saves orders in the same place.
- 03
Customers sign in once
The same account works on the web and in the app, with the same order history and saved details.
- 04
The cart follows them
Items added on one device appear on the other.
- 05
You manage it all in one place
Change a price or add a product in your store, and the app updates too.
Use cases
What you can do with it
Shared catalog, cart, and account
One store, one login, one cart across web and app.
Push notifications
Send short alerts to customers' phones about sales, restocks, or order updates.
Faster checkout
Let shoppers pay in a few taps with saved details, Apple Pay, or Google Pay.
Wish lists and reordering
Make it easy for customers to save favorites and buy again.
Loyalty and rewards
Offer points, member pricing, or app-only deals.
In-store helpers
Let shoppers scan a barcode for details or check stock at a nearby location.
Why it matters
Why it matters for your business
Many shoppers browse and buy on their phones. An app puts your store one tap away on their home screen.
- Keep customers coming back. A well-timed alert can bring a shopper back without paying for an ad.
- A smoother experience. Apps can feel faster and simpler than a mobile website.
- No double work. Because the app shares your store's data, you don't manage a second catalog.
- Stronger loyalty. Rewards and saved preferences give customers a reason to choose you again.

How Hart builds it
01
Understand your shoppers
We learn who buys from you and what they need from an app.
02
Choose the right approach
We help you decide between native apps or one shared, cross-platform app (explained below).
03
Design the screens
We sketch and test simple, clear layouts before building.
04
Connect to your store
We link the app to your catalog, cart, accounts, and payments.
05
Test and publish
We test on many devices, then handle submission to the Apple App Store and Google Play.
06
Support and grow
We fix issues, keep up with phone updates, and add features over time.
Platforms
Platforms we use

Swift for iPhone (iOS) and Kotlin for Android. "Native" means built specifically for each type of phone.
Cross-platform apps
React Native and Flutter. "Cross-platform" means one app built once that runs on both iPhone and Android.
Store platforms
Shopify, Magento (Adobe Commerce), WooCommerce, BigCommerce, and custom-built stores

Do I need an app if I already have a mobile-friendly website?
Not always. An app makes the most sense when you have repeat customers. We'll give you an honest recommendation.
Should I choose native or cross-platform?
Cross-platform is often quicker and more budget-friendly. Native can be best when you need top performance or special phone features. We'll explain the trade-offs for your case.
Will I have to manage products in two places?
No. The app pulls from your existing store, so you update things once.
Can customers use the same login on the app and website?
Yes. One account works in both places, with the same order history and saved details.
Do you handle getting the app into the App Store and Google Play?
Yes. We prepare and submit the app and handle the review process for you.
What happens after launch?
We can keep your app up to date as Apple and Google release new phone software, and help you add new features.
