How to Improve Customer Engagement in Retail Apps

Retail customer engagement is the set of interactions that move app users toward a useful shopping action: product discovery, offer activation, loyalty use, add-to-cart, purchase, or repeat visit.

Mobile apps already play a direct role in retail sales. According to Forrester, 37% of US online adults regularly use retailer mobile apps to make a purchase. In its review of 10 leading US retail apps, Forrester highlighted product discovery, recommendations, useful shopping tools, browsing, and fulfillment as characteristics of stronger app experiences.

Relevance is another gap. Adobe’s retail study of 2,085 consumers found that 69% want retailers to anticipate their needs with relevant offers or information at the right moment, while only 35% say brands do this effectively. For retail apps, this turns customer engagement into a set of measurable jobs.

1. Improve product discovery beyond search

How can retail apps improve product discovery?

Retail apps can improve product discovery by creating additional routes into the catalog: curated collections, stories, product carousels, quizzes, product finders, and category-specific banners.

The format should match the discovery problem:

Forrester’s retail app review gives concrete examples. Lowe’s Style Studio lets users start with an image of their space and discover products that fit it. Kroger’s OptUP uses previous purchases to recommend products. Both extend product discovery beyond a standard catalog search.

Retail strategist Ian Dewar, who has worked across The North Face and Anthropologie, makes a similar point in an AppsFlyer interview: “The future of where apps really add value is this ability to intertwine content, storytelling, brand messaging with the ease to product discovery.”

Leroy Merlin used in-app stories to give products and categories additional discovery points. The content included tutorials, product updates, quizzes, Product of the Week, and Discount of the Month.

In the first month:

• 24% of monthly users interacted with Stories.
• CTR reached up to 47%.
• Users opened more than 1 million Stories.

For a retail app engagement campaign focused on discovery, opens and CTR are intermediate metrics. The stronger test is what happens next: category visit → product view → add to cart → purchase.

2. Place promotions where purchase intent already exists

How can retail apps make promotions more effective?

Retail apps can improve promotion response by matching the offer to the user’s current action. A category visit, active cart, loyalty status, recent purchase, or expiring coupon gives the promotion a clear context.

Alibaba turns user actions into discovery moments. After a screenshot, the app can suggest sharing the product or exploring similar items. When a shopper starts leaving the basket, it can surface an incentive before intent disappears. The key point is timing rather than a pop-up itself - the offer appears inside an active decision.

InAppStory supports these scenarios with smart banners, stories, in-app messages, promo-code widgets, product cards, and checkout mechanics. The placement can sit on the home screen, near a category, inside a loyalty flow, or before checkout.

3. Make loyalty benefits visible when users can use them

How can retail apps increase loyalty engagement?

Retail apps can increase loyalty engagement by showing rewards at the point where they affect a decision. Users should not have to open a separate loyalty section to discover that they have an available coupon, member price, expiring points, or a benefit close to redemption.

There are several points to surface loyalty points:

• Home screen: points balance, tier status, expiring rewards.
• Product or category page: member price, cashback, bonus points.
• Cart and checkout: available coupon, free shipping, reward redemption.
• After purchase: progress toward the next tier or reward.
• Reactivation: unused benefit or personal loyalty offer.

Salesforce identifies three common shopper complaints about loyalty programs: rewards take too long to earn, are not valuable enough, or expire before customers can use them. These are communication problems as much as program-design problems. A strong retail app engagement flow makes the value and timing of a benefit clear before the opportunity disappears.

Carrefour Italy uses in-app stories to surface PAYBACK loyalty benefits, promotions, and seasonal campaigns on the app homepage. Content can be adapted by user segment and region, giving loyalty offers a visible place in the shopping journey instead of leaving them inside a separate program section.

For loyalty-focused customer engagement in retail, measure reward views → redemption → purchase → repeat purchase. Enrollment alone does not show whether customers actually use the program.

4. Collect preference data directly in the app

How can retail apps collect zero-party data?

Retail apps can collect zero-party data by asking users for preferences directly: through short polls, quizzes, product finders, and in-app surveys. The answers can then shape product recommendations, collections, offers, and future campaigns.

The most useful questions are tied to an immediate shopping task:

InAppStory’s retail framework uses polls and quizzes for preference collection, product finders, style quizzes, and “this or that” mechanics. The important step comes after the answer: preference data should change what the user sees next.

Airship’s Experience Impact study analyzed more than 1,000 in-app retail experiences across 1.7 billion device sessions. Customers shown experiences that asked about their interests and preferences had 2.5× greater purchase conversion (+179%) than customers who were not shown those experiences. 

5. Connect content directly to shopping actions

How can retail apps turn content into commerce?

Retail apps can make content shoppable by connecting stories, videos, guides, collections, and UGC directly to product cards, product pages, add-to-cart actions, or checkout.

A user who discovers a product in content should not have to search for it again.

In practice, the path can be as short as story → product card → add to cart, or quiz → personalized collection → product page. InAppStory’s embedded commerce mechanics support shoppable stories, product carousels, product feeds, add-to-cart actions, and checkout flows inside the mobile experience.

This is also how Vlad Lastovsky, CEO of InAppStory, describes effective in-app content: “They guide action, highlight value at the right moment, and reduce friction between ‘interest’ and ‘action’.”

METRO used in-app stories for Product of the Day, product discovery, recipes, culinary tips, quizzes, and polls. Content gave users additional routes from expertise and promotions into products.

After implementation:

• 52% of app users actively opened stories.
• Product-purchase conversion increased by up to 37%.
• Average session length among users engaging with Stories increased by 34 seconds.

The useful metric here is not content consumption alone. For shoppable content, track content view → product interaction → add to cart → purchase.

This gives mobile app engagement a direct commerce outcome: content helps users discover and evaluate products, then removes steps between interest and purchase.

6. Use gamification to change shopping behavior

How should retail apps use gamification?

Gamification in retail works best when the game is tied to a specific customer action: return to the app, explore a category, redeem a loyalty reward, activate a promotion, or interact with a partner offer.

The game itself is not the KPI.

Papa Johns is a QSR brand rather than a traditional retailer, so this case should not be used as evidence of retail sales uplift. It is useful for a different reason: it shows how a gamification mechanic can connect a specific product with a concrete commercial action.

For the launch of its Shawarma Pizza, Papa Johns created a game in which players sliced the actual ingredients used in the product. In the standard mode, players could earn a promo code for a free pizza. The campaign flow connected promotion → game → reward → restaurant visit.

The campaign recorded:

• 12,951 unique players
• 35,614 game sessions
• about 3 sessions per player on average
• 42.5 seconds average session duration
• 420+ hours of total playtime

The transferable lesson for retail customer engagement is the campaign structure. The product itself became part of the gameplay, while the reward gave users a defined next step.

A retailer could apply the same logic to a new product line, seasonal assortment, supplier campaign, or loyalty offer:

game → product or reward → redemption → purchase

For retail, the final measurement should therefore include reward redemption, product or category visits, purchases, repeat behavior, and incremental margin. Game starts and playtime show participation; they do not establish commercial impact on their own.

7. Turn app attention into retail media

What is retail media in a mobile app?

In-app retail media is advertising sold on a retailer’s or marketplace’s own mobile app inventory. It can include sponsored products, sponsored collections, display placements, video, brand content, and interactive campaigns.

IAB Europe classifies this as on-site retail media: advertising that appears on a retailer or commerce media network’s own digital properties, including websites and mobile apps.

This is becoming a substantial part of digital advertising. IAB Europe’s AdEx Benchmark, covering 30 European markets, found that retail media spend grew 16.7% in 2025 to €13.3 billion, accounting for more than 10% of European digital ad spend.

For retailers, the mobile app creates several possible retail media placements:

InAppStory’s retail mechanics include sponsored stories, product carousels, partner shelves, in-app landings, banners, and branded mini-games. A sponsored collection can give a supplier premium visibility; a branded game can turn the same placement into a larger partner activation.

A retail app can therefore serve two roles at once: a shopping channel for customers and a measurable media surface for brands that want to reach those customers close to purchase. 

What we have learned about retail customer engagement

At InAppStory, we see retail customer engagement primarily as an attention-management problem. Retail apps often contain many valuable scenarios at the same time: product discovery, promotions, loyalty benefits, seasonal campaigns, partner offers, and checkout. The challenge is deciding which of them deserves the user’s attention at a particular moment and giving that attention a clear next step. This is also how we approach in-app communication across different app scenarios.

This view comes from years of working with mobile app teams and seeing hundreds of in-app use cases. Across that experience, one pattern repeats: the format itself rarely determines the result. A story, banner, quiz, game, or product carousel works when it is connected to a real customer task and a measurable business action.

Our recommendation is therefore to start a retail engagement strategy with the behavior rather than a mechanic. Define what should change: category discovery, reward redemption, cart recovery, repeat purchase, or response to a partner campaign. Then choose the format, placement, audience, and timing around that action.
