The most impressive aspects of CrustLab’s work were the level of technical expertise and ability to understand the project from a business perspective. They cared about our goals from the beginning, which helped us plan better and develop faster.
CrustLab’s implementation of our solutions has almost doubled our revenues. All aspects of cooperation were very good. I felt that we were treated as very important clients because we received a very high standard of service. The team delivered the results at the time and budget.
The CrustLab with the experienced team gave us a lot of development energy to build a user-friendly application. Within two weeks, they delivered the first round of iOS and Android apps. Within 3 months our application was launched without any major bugs. The quality is the DNA of the CrustLab.
CrustLab consistently adds value to our organization in many ways. We’ve received very positively feedback on the system CrustLab has delivered. Our customers regard it as an excellent product. Our experience working with them has far exceeded those of other vendors.
We hired CrustLab to introduce several modifications to improve one of the Pocco Finance apps and integrate it with the new version of the SDK. The project was completed on time and in line with the planned budget. I strongly recommend CrustLab as a software partner.
We are really satisfied with the cooperation with CrustLab. Very good technical skillset, good communication, and work done on time! After creating a customizable widget, we entrusted them with redefine of another application, and the results are splendid.
I was looking for a design team that had experience in sports betting. CrustLab helped me complete a full UX design project for my product. It was a very collaborative process, which is what I wanted. When I’m ready to do my next project, they’re going to be my first phone call.
Our cooperation with CrustLab concerned body leasing. They offered us highly skilled and experienced Android developers. I am fully satisfied with the ease of contact, the speed of completing the formalities, but most of all of the man they recommended to us.
This team is hungry, sharp, “on it” and very customer-focused. I had no idea that I could find such great help from the other side of the world – especially a firm that could understand our product requirements even though I’m not a tech product manager.
We take advantage of CrustLab’s experience in the field of payments, new functionalities, and user-friendly design. The development process itself ran smoothly and according to plan. It was important for us to complete the project on time, so I cannot imagine a better partner for this project.
CrustLab successfully delivered a product that was able to maintain its performance despite some sudden surges in the site’s traffic. Thanks to their experience and ability to predict problems, we found solutions and built the project on time.
The best part of working with CrustLabs was their attention to detail in every development process step. They were great about taking the initiative to suggest new enhancements and features that our product owners hadn’t thought of and sharing with us the best practices.
CrustLab was able to successfully deliver a fully-functioning product, much to the client’s delight. The team was highly communicative, and internal stakeholders were particularly impressed with CrustLab’s management skills. They’re on a straight road to success.
We finished an MVP in 3 weeks. It was very valuable that CrustLab was able to evaluate the feasibility of our solution and estimated the effort and cost that was required to request the funding. CrustLab can be a business partner in addition to an excellent software development agency.
The team provided professional services that added value to the core functions of the business. They were fast and felt like our internal IT department, working during the night when we were deploying important features. That was fantastic, and I’m happy they’ve worked with me.

During this phase, we follow your business assumptions so you can be sure that the final UI design will be consistent with your brand.
Agile Development
Now it is time to turn mockups into reality. Following a standard Scrum procedure, our Flutter app developers work in sprints to write the source code. Once the app is ready, it undergoes a complete quality assurance process performed by qualified QA/QC testers to ensure it runs properly. Whenever it’s possible, we automate the processes to speed up the delivery of your app.
As we favor transparency and open communication with our clients, you are engaged in the whole procedure and have a direct insight into ongoing issues during regular Sprint Retrospectives.

Frequently asked questions
Would you like to learn more about Flutter? Browse our FAQ for more details!
- Can I reduce the costs of the project by developing my app in Flutter?
Yes, definitely! Thanks to the Flutter app development service, you can operate on multiple platforms using only one source code. The development process of a cross-platform app is quicker, cheaper, and more flexible compared to native applications that require several teams to write separate codes for each operating system. Even though it takes more time to develop a cross-platform feature, it is still much quicker than creating native ones for two apps separately.
- Flutter or native app – which one is a better option for my project?
Deciding whether to go for native or Flutter app development is a primary concern that can have serious long-term consequences. That’s why you should review your project’s requirements and specify demands before making a final choice.
Due to unified development, Flutter can reduce product development costs and decrease its time-to-market, so it is advised for businesses that care for the product’s quality but have limited resources. Building an app in Flutter is also convenient when your UI incorporates a number of unusual interactions, which you want to stay consistent across different platforms.
However, more expensive native development provides greater flexibility for UI components fine-tuning. Despite its broad functionality, the Flutter framework is unquestionably more limited in this regard, at least for now.
Additionally, although Flutter is considered to provide near-native UX much quicker and cheaper, it still has its limitations in comparison to native technologies. So if performance and speed are critical for your application, you should probably consider developing it natively.
- Can a Flutter app include the same features as a native app?
Yes, it can. Flutter has developed so dynamically that any native feature can be built in this framework as well. It can be implemented directly in the Flutter architecture or bridged from native libraries.
- Is Flutter the only cross-platform technology?
According to statistics, Flutter is the youngest and most popular cross-platform app development framework. But it is not the only cross-platform solution available on the market.
The greatest competition for the Flutter framework is React Native based on JavaScript. Cordova, Ionic, and Xamarin also have fans, but their market share is dropping. Other cross-platform technologies include Unity, NativeScript, PhoneGap, Kotlin Multiplatform, Apache Flex, Kendo UI, Kivy, and many more.
Nevertheless, companies tend to choose Flutter app development due to its popularity, versatility, and flexibility.
- Which programming language is used in Flutter development?
Flutter applications are written in Dart – an object-oriented language optimized for client apps. The Dart virtual machine and the underlying graphics framework are created in C/C++.
Dart’s adoption of the Hot Reload feature facilitates productive development. Thanks to this functionality, it is possible to introduce modifications into a running application and see the results immediately.
- What is Flutter?
Flutter is an open-source UI framework launched by Google. It enables the development of cross-platform applications for a wide range of operating systems, including iOS, Android, Windows, macOS, and Linux. Flutter is designed for building mobile, web, and desktop apps from a single codebase.
Although Flutter is a cross-platform solution, applications developed in this framework are characterized by a close-to-native User Experience.
