The 7 Best Shopify Apps to Boost Sales

Several types of Shopify apps can help grow your brand. This list will break down the top Shopify apps in each category.

1. Okendo

Okendo is a comprehensive customer marketing platform designed to enhance various aspects of customer engagement for Shopify brands. While it offers a robust Reviews product that facilitates the collection and display of customer reviews, Okendo’s capabilities extend beyond just reviews to help brands create revenue-driving customer experiences.

  • Reviews: Collect and showcase customer reviews to build trust and drive conversions.
  • Loyalty: Implement points and rewards systems to encourage repeat purchases and maximize customer lifetime value.
  • Referrals: Turn customers into brand advocates to scale word-of-mouth marketing.
  • Quizzes: Match shoppers with products they love, enhancing the shopping experience and increasing sales.
  • Surveys: Gather insights to improve customer experiences and understand your audience better.

  • App type: Customer Marketing Platform
  • Noteworthy customers: SKIMS, Netflix, Ridge, ILIA Beauty
  • Best feature: Customization and User experience

Okendo stands out with its customizable features across all five solutions. For example, you can tailor review widgets to highlight the product & customer attributes that matter most to your customers, giving you insights that can shape your marketing strategy. Whether you want written or video reviews, you have control over how they appear on your website, making sure the display fits seamlessly with your brand’s identity with minimal impact to site speed.

Okendo also makes it easy to integrate with your existing tech stack, thanks to strong customer support throughout the process and over 50+ partnerships and integrations. It integrates well with tools like Klaviyo, Attentive, and Postscript, providing valuable data for better audience segmentation in your email and SMS campaigns that drive more sales. Plus, Okendo is affordable and doesn’t lock you into long-term contracts, offering great results without stretching your budget.

2. Rebuy

In 2025, tens of millions of online stores are competing for customer attention. Without a pleasant user experience, you’re likely going to lose out on potential sales. Rebuy delivers an elevated shopping experience, using powerful personalization engines to track customer behavior and create individualized shopping journeys.

  • App type: Personalization & upsell
  • Noteworthy customers: Magic Spoon, Blenders Eyewear, SIO Beauty
  • Best feature: AI-powered product recommendations

Rebuy’s machine learning algorithms analyze customer behavior, purchase history, and browsing data in real-time to make personalized recommendations like complimentary product upsells. It is highly customizable, allowing you to create landing pages for specific customer profiles complete with product displays relevant to your target audience. Rebuy integrates seamlessly with most Shopify apps, as well as several third-party marketing tools like Klayvio.

Perhaps Rebuy’s greatest distinguishing feature is its proprietary Smart Cart™ technology. Similar to a grocery store checkout line, customers are typically more likely to buy small upsell items once they have already made a decision to purchase. Smart Cart™ capitalizes on this consumer behavior, using browsing preferences to tailor individualized in-cart upsells, cross-sells, or dynamic discounts.

Rebuy offers an individualized, elevated shopping experience for your customers, presenting relevant products and deals to enhance their shopping journey and maximize the value of each visit to your site.

3. Recharge

The subscription model has taken the world of online commerce by storm—and it’s easy to see why. Customers are increasingly accustomed to paying ongoing subscriptions for products and services that provide value, and for brands with a loyal customer base, this recurring revenue can be a game-changer. That’s why Recharge stands out as one of the best Shopify apps for boosting sales revenue.

  • App type: Subscriptions & retention
  • Noteworthy customers: 1st Phorm, LOLA, Blueland
  • Best feature: Customizable subscription packages

While recurring subscription revenue is highly appealing, managing those subscriptions manually can quickly become a major headache—especially if your brand frequently updates products or services. Poor subscription management can frustrate even your most loyal customers.

Recharge allows you to deliver a flexible and seamless subscription experience to customers with customizable subscription packages and an easy-to-use self-service portal. Customers can manage everything from the self-service portal, from updating payment details to managing delivery dates to choosing product packages. You can offer curated subscription packages with flexible delivery dates, fulfilling a wide range of customer preferences.

Recharge integrates seamlessly with Shopify as well as a host of third-party apps including Klayvio and Avalara, and offers a robust analytics dashboard where you can view customer churn rates, subscription performance, and revenue growth. If you aim to implement a subscription model in your brand, Recharge is a must-have Shopify app.

4. Tapcart

Especially with the advent of social media, online shopping is no longer an activity reserved for desktops so it is crucial to have a solid shopping experience on mobile. Having a dedicated mobile app is the best way to deliver that shopping experience, but without expert coding knowledge, this can be a costly proposal. This is where Tapcart comes in.

  • App type: App builder
  • Noteworthy customers: Oh Polly, BYLT Basics, Brumate
  • Best feature: Drag-and-drop app customization

Tapcart allows you to create a fully customizable mobile app without any coding knowledge at an affordable price. Their drag-and-drop customization features give you the ability to build a mobile app aligned with your brand’s visual identity, from customized layouts to brand assets and colors.

The Tapcart integration syncs seamlessly with your Shopify store and other solutions like Okendo, ensuring consistent inventory management and a unified experience across all consumer touchpoints. Don’t miss out on the potential revenue from mobile purchases—Tapcart is a must-have Shopify app for building a mobile app without the high costs of custom development.

5. Postscript

Direct-to-consumer messaging is essential for marketing your brand, but outsourcing to a digital marketing agency can be very costly with no guaranteed return on investment. If you want to take advantage of SMS marketing at an affordable price, Postscript offers tiered pricing plans to meet your brand needs.

  • App type: SMS
  • Noteworthy customers: Caraway, Feastables, True Classic
  • Best feature: Advanced segmentation and automation

Postscript uses historical Shopify data to identify customer segments and craft tailored messages that speak directly to your target audience. With built-in TCPA-compliant safeguards, Postscript allows you to build consumer trust without spamming their inboxes. Automated triggers send messages at key points of the customer journey to keep your audience engaged and drive them toward a purchase.

Postscript also allows for two-way messaging, giving you a personalized customer support channel with direct access to your target audience. With its affordability and ease of use, Postscript makes SMS marketing accessible for brands of all sizes.

6. Nostra

One of the more understated yet impactful Shopify apps on this list, Nostra, improves your website’s speed, drastically reduces latency, and boosts page load times. Customers won’t give your website the benefit of the doubt if it offers a poor user experience. If slow load times are preventing you from capitalizing on website visits, Nostra can help.

  • App type: Site speed
  • Noteworthy customers: Jolie, Glamnetic, Cozy Earth
  • Best feature: Edge delivery engine

Nostra uses over 310 edge servers around the world to deliver content, significantly reducing load times for your Shopify store. Not only does it improve site responsiveness, but it optimizes core web vitals for important SEO metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).

While there may be other apps that improve site performance, Nostra distinguishes itself with the ability to scale. During promotional events or periods of heavy traffic, Nostra’s robust infrastructure ensures your store can handle surges while maintaining a smooth shopping experience.

Website load times play a crucial role in user experience and conversion rates. While it may not be the flashiest app on this list, Nostra is undoubtedly one of the best Shopify apps to boost sales.

7. Shoplift

Data is king, but with limited team bandwidth and strict design budgets, A/B testing is an often forgotten art in marketing. Even if you are able to create multiple versions of the same asset and implement them effectively, analyzing the results can be both time-consuming and costly. Shoplift allows brands to run impactful split tests at scale without wasting extensive design or development resources.

  • App type: A/B testing
  • Noteworthy Customers: Ninepine, &Collar, Great Jones
  • Best Feature: Lift Assist™ for auto-generated tests

Shoplift Lift Assist™ Technology analyzes millions of shopper sessions to recommend high-converting elements for your brand, like countdown timers or sticky carts. You get recommendations on creative assets that resonate with your audiences, gathering data to inform your future marketing efforts.

With Shoplifter’s analytics platform, you can uncover specific factors that influence key performance metrics, whether it’s messaging, landing page elements, or navigation menus. Shoplift helps you deeply understand the preferences of your consumers, making it one of the best marketing apps for Shopify.

What Types of Shopify Apps Can Boost Sales?

All of the apps listed above are excellent tools for increasing conversions on your Shopify store. These various app categories leverage different marketing strategies to boost sales; below is a breakdown of how each type of app accomplishes this.

Review and Social Proof Apps

Review apps leverage the goodwill gained from your current customers to help nurture future customers along your sales funnel. Seeking a product review is often the first step a consumer takes toward making a purchase so review and social proof apps help capture that interest.

Customer Loyalty and Retention Apps

Especially when you offer a consumable product, customer loyalty, and retention apps can create substantial revenue streams through recurring purchases.

Conversion Optimization Apps

Apps that remove barriers to purchase fall into the category of conversion optimization apps. These apps remove friction in the process of purchasing, capturing sales that would have otherwise not materialized because of a poor user experience.

Cross-Selling and Upselling Apps

Upsell apps capitalize on customers who have already decided to purchase by creating personalized offers or dynamic discounts to push products that might be complementary to the original purchase.
