How to add ‘sticky’ features like wishlists and wallets in your app

Your Shopify app retention features determine whether users stay or churn.

Why ‘Sticky’ Features Matter More Than Ever

User retention should be your ultimate app goal. You can spend time and money to acquire thousands of users, but if they abandon your app after minimal use, all your efforts are wasted. Success stories from Shopify and various Reports show how adding app features such as wishlists and wallets can increase levels of engagement and repeat purchases. McKinsey also states how just a 5% increase in customer retention can increase profits from 25% to 95%. But still, many apps continue skipping out on great features, settling for basic functionalities.

The truth is: The difference between a good app, and a great app is the ability to make users stay. Adding these ‘sticky’ app features will be your secret weapon.

How ‘Sticky’ Features Convert Users into Loyal Fans

‘Sticky’ features are more than simply nice features of the app. They are an integral part of the user experience with the app, and can make the app become indispensable in the user’s routine. For example, wishlist features allow users to save their favorites, which encourages them to make a purchase in the future. Wallet features increase trust and user app convenience as they allow for single-touch payments.

A recent study by Shopify states that approximately 78% of consumers have made purchases as a result of them adding those items to a wishlist. Also to note, wallets connected to apps have 40% higher conversion rates (Boston Consulting Group). When these features are integrated to work as a system, these casual visit features become buyers who come back time after time.

Making ‘Sticky’ Features: Step by Step for Your App

1. Adding Wishlists: Your Digital Shopping Assistant

Whether or not to have a wishlist is no longer a question for online retailers, as they are a common industry standard. They enable users to customize the shopping experience by organizing their favorites, and browsing later.

How to do it step by step via no code tools like Twinr:

  • Employ a drag and drop interface to integrate wishlist SDKs/scripts by yourself and without the need for a developer.
  • Ensure wishlist buttons are placed strategically within product pages for simple and quick access.
  • Setup session and device persistent storage so that users’ wishlists are saved across devices and sessions.

Benefits:

  • Shopify states that a whopping 63% of users that add items to their carts ultimately abandon their carts, and wishlists work as a solution.
  • Users want to come back to increase their saved items, and wishlists can enhance this by a whopping 34%.

2. Embedding Wallets & Payment Storage Securely & Seamlessly

A seamless checkout experience is essential. Digital wallets, such as Apple Pay, Google Pay, or PayPal, expedite the checkout process and increase trust—two vital components noted by BCG, which found that in e-commerce, sales increase by 30–40% with speedy checkout options.

How to implement:

  • Use Twinr’s dedicated custom code injection feature to embed SDKs that support wallets.
  • Display wallet icons at checkout to give users peace of mind regarding transaction safety.
  • Utilize the native performance enhancements to ensure users don’t experience delays and that the transaction is automatically processed.

Benefits:

  • Confidence risk is allayed and data, payment, and resources are more readily available.
  • Secure and intuitive apps make users more likely to trust the platform and mentally bank information for future transaction use, thereby increasing abandonment of other payment options.

Making ‘Sticky’ Features Truly Unstoppable

3. Personalize & Synchronize Data for Consistent Experiences

Disconnected data can kill engagement, and with the app, data should never feel disconnected. Users should have seamless, synchronized experiences of wishlists and wallets that are available across devices and sessions. With Twinr’s real-time sync, user populated data like preferences, items, and payment information are current.

Think of it: Apple Wallet’s seamless functionality across all iOS devices is a perfect example of what you want to emulate with your app. Your ‘sticky’ features no longer serve a functional purpose; they provide an experience, and that experience is personal and reliable.

4. Gamification: Incentivizing the Usage of Functions

Using gamification techniques like progress meters and badge systems like “Wishlist Explorer” helps drive the engagement with wishlists and wallets. Users will then build collections and reward activity through discounts and exclusive offers.

5. Wishlist Reminders and Re-Engagement Notifications

Users with generic push notifications about wishlists and even unprocessed payments. Automated notifications help regain lost attention and enhance retention.

6. Repetitive Participation: User-friendliness and Enjoyable Experiences

An effort-free process should be the focus of your system: onboarding should be seamless, and intuitive navigation through functions should be frictionless. User testimonials like, “Over the past three months, wishlists increased my sales by 30%,” are incredibly effective.

7. Providing User Wallets: Security and Reputation are Vital

Assure the users of their data’s privacy as wallets are utilized. Users should be shown your PCI compliance, and trust and security seals should be visible on the site.—
