Shopify Mobile App: Should You Build One for Your Ecommerce Store?

The Mobile App Question Every Growing Store Asks

At some point, every founder with a growing Shopify store asks: “Should we build an app?” The intuition is understandable — apps feel premium, native experiences are smoother, and push notifications are more powerful than email. But the decision requires honest economics: app development costs £20,000–£80,000, app store acquisition is expensive (cost per install on iOS typically £1.50–£5.00), and app retention requires ongoing content and notification strategy. For most Shopify stores, the answer is not yet — but the exceptions are real.

When a Mobile App Genuinely Adds Value

Apps outperform mobile web when: purchase frequency is high enough to justify installing an app (weekly or more), the product experience requires native device features (camera for AR try-on, Bluetooth for connected products, GPS for service delivery), push notification engagement is a core retention strategy, or the subscription model means customers need to manage their account regularly on mobile.

Categories where Shopify brands successfully operate apps: subscription boxes, pet care (daily feeding logs, vet booking), fitness equipment (workout tracking integration), and fashion (weekly new arrival browsing). Common thread: high engagement frequency and feature requirements beyond a browser can deliver.

No-Code App Builders for Shopify

For stores that want an app without custom development costs, no-code app builders convert your Shopify store into a native iOS and Android app. Tapcart, Vajro, and Shopney are the market leaders. These apps sync your Shopify catalogue, handle cart and checkout via Shopify’s native checkout, and add push notification capabilities. Cost: £250–£600/month versus £50,000+ for custom development. The trade-off: limited customisation versus full native app flexibility.

For most stores in the £500K–£5M revenue range evaluating their first app, a no-code builder is the right starting point. It validates whether your customers will install and engage with an app before committing to a full development budget.

Progressive Web App as an Alternative

A Progressive Web App (PWA) is a website that behaves like an app when installed on a mobile home screen: it loads offline, can send push notifications, and runs full-screen without the browser UI. PWAs are significantly cheaper than native apps (£5,000–£15,000 vs £50,000+), require no App Store approval, and update automatically without forcing users to update. Shopify stores can implement PWA functionality without completely rebuilding — service workers and a web app manifest add the core capabilities to an existing Next.js or custom theme build.

Push Notifications vs Email and SMS

The primary commercial argument for an app is push notifications. Push notification open rates average 7–15% — lower than SMS but with zero per-message cost and no carrier compliance requirements. For a store with 20,000 app installs, a push campaign costs effectively nothing per send and reaches engaged users who chose to install your app (high intent signal). This math works at scale. For a store with 500 app installs, the push notification investment is unlikely to justify the app development and maintenance cost.
