The digital world keeps evolving, and while in many countries technology is part of everyday life, there are a billion people getting online for the first time. This group is known as the Next Billion Users (NBU).
Designing digital experiences for the NBU isn't simply about adapting what already exists. It's a challenge that requires understanding these users' technological, cultural and educational constraints, and creating interfaces that are accessible, intuitive and efficient in environments with limited connectivity and resources.
We'll explore the main challenges of UX in emerging markets, the key strategies for designing effective products, and real success stories in this space.
Key challenges in UX for emerging markets
Designing for the NBU presents unique challenges that don't usually come up in markets with advanced access to technology. Here are some of the most relevant ones:
📌 1 Limited connectivity and intermittent internet access
In many emerging markets, internet access is unstable or expensive. Users:
- Rely on 2G/3G networks or intermittent Wi-Fi connections.
- Buy limited mobile data, which restricts their use of heavy apps.
- Can't update apps constantly due to lack of data or storage.
🔹 How to solve this in UX?
- Design "offline-first" experiences that let the app be used without a connection.
- Reduce the app's footprint with Lite versions or progressive functionality.
- Compress images and videos to optimize data consumption.
📌 Example: Google Maps lets you download maps and navigate offline, ideal for regions with unstable internet.
📌 2 Low-cost devices and limited storage
NBU users often access technology through low-end phones with little RAM and limited storage. This affects app loading speed and multitasking capacity.
🔹 How to solve this?
- Optimize the code so the app runs well on devices with less than 2GB of RAM.
- Implement progressive loading for images and content to reduce memory impact.
- Let users clear cache or disable features to save space.
📌 Example: Facebook Lite is under 2MB and works on 2G networks without losing essential features.
📌 3 Digital literacy: Navigating an unfamiliar world
Many NBU users have never used a smartphone or digital apps before. They aren't familiar with gestures like swiping, zooming or double-tapping.
🔹 UX solutions:
- Use large, visible buttons instead of relying on advanced touch gestures.
- Include interactive tutorials that explain key features.
- Design with immediate visual feedback, like color changes or vibrations when tapping a button.
📌 Example: WhatsApp shows step-by-step instructions the first time a user opens the app.
📌 4 Cultural and language barriers in the digital experience
NBU users come from diverse cultural backgrounds, where language and visual conventions may differ widely. An icon that seems obvious to a Western user, like an envelope for "mail," may not make sense in other cultures.
🔹 How to design for this reality:
- Avoid abstract icons and favor universally recognized symbols.
- Offer multilingual interfaces with automatic translation.
- Consider writing direction, since some languages read right to left.
📌 Example: Google designed digital keyboards for languages like Hindi, letting users type phonetically.
2. Strategies for designing accessible, effective experiences
Now that we know the main challenges, let's look at how to overcome them with good UX practices:
✅ 1 Optimization for low-end devices
- Use lightweight image formats (WebP instead of JPG or PNG).
- Avoid heavy animations that consume processor resources.
- Implement dark mode to save battery on OLED screens.
✅ 2 Offline-first experiences
- Allow content downloads for offline use.
- Temporarily save forms to submit them once there's internet access.
✅ 3 Inclusive interfaces for low-literacy users
- More images, less text.
- Offer voice assistants for those who can't read.
- Include simple symbols instead of technical terms.
📌 Example: Google Assistant in India lets users use voice commands in several local dialects.
4. Success stories in UX for NBU
Designing for emerging markets isn't just a challenge — it's also an opportunity for innovation. Many companies have managed to adapt their products for the NBU, creating effective, scalable solutions. Below, we look at three success stories that have made a positive impact in these markets:
📌 4.1 Google Go: A browser built for limited connectivity
Google noticed that many users in emerging markets struggled to access the web due to low-end devices and slow connections. In response, they launched Google Go, a lightweight browser designed specifically for these users.
🔹 Key features:

✅ Fast page loading even on 2G/3G networks.
✅ Data-saving mode that cuts internet usage by 40%.
✅ Voice search, ideal for low-literacy users.
📌 Impact: Google Go became an essential tool in countries like India, Nigeria and Indonesia, letting more people get online without technical limitations.
📌 4.2 YouTube Go: Video without relying on a stable connection
YouTube is one of the most popular platforms in the world, but in emerging markets, streaming video isn't always viable due to unstable connections or expensive data plans. To solve this, Google launched YouTube Go, an optimized version of the platform.
🔹 Key features:
✅ Download videos to watch offline.
✅ Preview before downloading, avoiding unnecessary data usage.
✅ Video quality selection, letting users choose file size based on their data plan.
✅ Simplified interface for lower-performance devices.
📌 Impact: YouTube Go helped millions of users in countries like Brazil, India and Indonesia access video content without worrying about connectivity.
📌 4.3 Paytm: Financial inclusion for emerging markets
In many developing countries, access to banks and digital payments is limited. Paytm, an Indian startup, designed a payments app that became the main financial tool for millions of people without access to traditional banking services.
🔹 Key features:
✅ Simple interface without complicated financial jargon.
✅ QR code payments, removing the need for bank cards.
✅ Support for multiple local languages.
✅ Offline mode for making payments without an internet connection.
📌 Impact: Paytm revolutionized India's digital economy, letting small businesses and unbanked users access digital payments easily.
5. Common mistakes when designing for the NBU and how to avoid them
Designing for emerging markets requires understanding and empathy, but products often fail because they don't account for certain key factors. Here are some common mistakes and how to avoid them:
🚨 5.1 Ignoring the user's context
Many designers build interfaces based on their own context and not on the real conditions of the end user.
❌ Mistake: Designing interfaces that assume fast connections or high-resolution screens.
✅ Solution: Run user testing in the real environment and design for multiple types of devices and connections.
📌 Example: A mobile payments app designed for New York may not work in Nairobi, where payment methods and user preferences are completely different.
🚨 5.2 Designing from the perspective of advanced users
Many apps assume users understand basic concepts like "create an account" or "swipe to navigate."
❌ Mistake: Excessive use of icons or advanced gestures without explanations.
✅ Solution: Interactive tutorials and clear text that explain essential features.
📌 Example: WhatsApp simplified its interface so any user can send a message without complicated setup.
🚨 5.3 Not optimizing app performance
If an app is too heavy, users with low-end devices will simply uninstall it.
❌ Mistake: High-resolution images, heavy animations and unnecessary background processes.
✅ Solution: Compress resources, optimize the code, and release Lite versions.
📌 Example: Facebook Lite is under 2MB and runs on devices with only 500MB of RAM.
6. The future of UX in emerging markets
UX design for emerging markets will keep evolving as more users get online. Some of the most promising trends include:
🚀 6.1 AI and adaptive design
Smart interfaces can detect the user's experience level and adjust the experience to their needs.
📌 Example: Google Assistant in India allows voice search in more than 10 local dialects, adapting to low-literacy users.
🚀 6.2 Expansion of digital payments
In many emerging markets, digital payments are still growing, but as mobile connectivity expands, more and more users will adopt digital wallets and cryptocurrencies.
📌 Example: M-Pesa in Africa lets people make transactions with just a phone number, no bank account required.
🚀 6.3 Growth of local platforms
Tech companies are starting to develop locally designed products instead of adapting Western solutions.
📌 Example: Byju's, an Indian education platform, offers content in multiple languages and formats tailored for children who have never used a computer.
