Top 100 Mobile App Developers in Eastern Europe
The Best of December 2025Looking for a top mobile app development company in Eastern Europe?
Building a mobile app is expensive. In fact, it can cost $10,000 to $150,000, unless you want an out-of-the-box solution with a DIY app builder. So, choosing the right app developer is important because it can save you time and money and result in an app that makes your business stand out.
As you begin the process of hiring an app development company, remember to define the type of app you want before starting conversations with developers. How complex your app idea is will determine your budget and the skill level you need in an app developer. Then, once conversations begin, ask for portfolio items, reviews, and references. Be sure to bring up timeline, too, so you align on expectations.
Overall, with about 90% of time on mobile spent in apps, investing in a mobile app for your business may help attract customers and get your brand in front of more people.
To assist you in your search for a partner, we’ve compiled this list of the top mobile app developers in Eastern Europe. Browse descriptions, feedback, and awards to find which can best suit your company’s needs.
