Shopify Mobile App ROI: How to Calculate It for Your Brand (2026)

Last updated: May 2026 | Reading time: 9 minutes

The business case for a Shopify mobile app is not hard to make. The data exists, the mechanisms are understood, and several UK brands have published results. What's harder is calculating your specific expected ROI before you commit.

This guide walks through the maths properly — not with a single illustrative number, but with the variables that actually drive the outcome.

The revenue levers an app touches

A mobile app affects revenue through three main channels. Understanding which ones apply to your brand determines your expected ROI.

Conversion rate uplift on mobile traffic. Native apps convert at 2-3x mobile web rates (Criteo, 2024 Mobile Commerce Report). If you're doing £2M/year with 60% mobile traffic and a 1.5% mobile conversion rate, and a native app improves that to 3%, the incremental revenue is roughly £600,000/year from the same traffic volume.

Push notification revenue. Push notifications are free per send. For brands with an opted-in install base, this is a new owned channel that generates revenue without paid media spend. A fashion brand with 8,000 opted-in users sending a collection launch notification at a 5% conversion rate and £85 AOV generates £34,000 per send.

Repeat purchase rate improvement. Van Heerde et al. (Journal of Marketing Research) found that branded mobile apps increase customer purchase frequency by 33% and average order value by 28%. For a brand where repeat purchases already drive meaningful revenue, the compounding effect of these improvements is significant.

Not every brand will see all three effects. The strength of each lever depends on your starting point.
