A complete guide to expanding your app internationally

After succeeding in your home market, it naturally leads to the question: what comes next? For many teams, it means expanding internationally.

The opportunity is significant, driven by increasing smartphone adoption (around 70% of the world population) and continued growth in app spending. Over the years, advances in the industry have also made reaching global audiences far more accessible.

The landscape is, however, complex. User expectations and acquisition costs are high, markets are saturated, and competition is intensifying. Each territory also brings its own user behaviors and challenges. Thus, international expansion necessitates rigorous planning and a data-driven approach.

In this guide, we outline the key considerations and practical steps to help you grow your app abroad.

With over 2.2 million apps available in both Google Play Store and App Store, standing out from existing solutions in any new market requires a clear understanding of where your app can deliver the most value.

Start your market research by answering a few critical questions:

• Who are your target users in this market?
• What problems are they trying to solve?
• How are competitors currently addressing those needs?
• Where are the gaps or areas for improvement?

Competitor analysis is especially useful here. Looking at app store reviews and user feedback can reveal what users like, and more importantly, what they don’t. These insights often highlight opportunities to differentiate your app through better features, user experience (UX), or positioning. 

From there, prioritize markets using clear criteria such as market size, competitive landscape, cultural fit, and monetization potential. Regulatory requirements and data privacy considerations should also be factored into market selection, as they can directly impact launch timelines and operations. 

You must approach app expansion as a series of experiments. First, pick one or two markets, use limited budgets, and treat this phase as a soft launch to gather early data to validate demand.

To track progress, you’ll need to define your key performance indicators (KPIs). Common metrics to measure include:

• Retention: Retention measures the percentage of users who return to your app over time.
• Lifetime value (LTV): LTV is the revenue a business can expect to generate from a group of users over time.
• Conversion rates: Conversion rate is the percentage of users who complete a desired action, such as an install or purchase.
• Cost per install (CPI) : CPI is the fixed amount an advertiser pays when a user installs an app.
• Cost per acquisition (CPA): CPA is the amount paid when a user completes a predefined action after installing an app.
• Return on investment (ROI): ROI measures the profitability of an investment relative to its cost.

Other useful indicators include your app store ranking and user ratings.

Expanding into a new market entails more than making your app available in another language. To perform well internationally, the app experience must be adapted to match the expectations of local users.

1. Adapt your product and user experience: Language is only one part of localization. User flows, onboarding, and overall UX need to be adjusted. Language changes can also affect layout and design, so interfaces need to be adapted to guarantee a consistent experience.
2. Adjust pricing and monetization: Rework pricing tiers, currencies, and payment methods to align with local purchasing behavior and market conditions.
3. Localize support and communication: Providing help content in the local language and ensuring that messaging feels natural can build trust and reduce friction. This includes everything from in-app messages to customer support interactions.

When done well, localization helps users understand your product more easily and interact with it more naturally, which can lead to stronger conversion and long-term growth.

Once your product is prepared for launch in a new region, your focus should shift to making it visible and appealing to local users.

Focus on app store optimization (ASO)

Localized listings, a core part of ASO, enable users to find and comprehend your app in familiar terms. You need to incorporate region-specific keywords and fully translate descriptions with cultural nuances in mind.

When you are expanding into new markets, ensuring your app functions as intended, regardless of network speeds, devices, and infrastructure, should be one of your top priorities. Users abandon slow or unreliable apps quickly, especially when alternatives are a tap away, so your backend must be capable of handling increased traffic without compromising stability.

Timing is everything when it comes to scaling. Scaling too soon can introduce unnecessary cost and complexity, while scaling too late risks slowdowns and outages that frustrate users. The goal is to scale when you see sustained increases in user demand, backed by clear usage metrics, and when your systems are technically ready to handle additional load.

Once your app is launched, performance data becomes the foundation for scaling. Adjust’s attribution and analytics bring together user acquisition, engagement, and revenue across markets, campaigns, and user cohorts, giving teams a complete view of what’s driving growth. With these insights, teams can optimize UA channels, fine-tune campaigns, and update strategy in response to real user behavior. As a result, apps can see higher conversion rates and better retention.

As expansion accelerates, speed becomes just as important as insight. Adjust’s AI-powered solution, Growth Copilot, helps teams answer critical questions in real time, such as which regions are driving the highest returns or where retention is strongest, enabling faster, more confident decision-making.
