In our HSS Digital mobile department, we develop applications for IOS & Android platforms with Flutter. Comparison with the websites, we can clearly say that mobile applications provide better communication between the brand and its users. You can capture many features that add value to the brand, such as notifications, remembering user information, the ability to send and use commands to other applications, the ability to be with users at any time, and the advantage of fast communication with the brand, thanks to mobile applications. We develop separately for each platform. (IOS, Android and Windows). Since we developed it independently of each other, you do not have to worry about whether there will be any compatibility issues. No matter what device users use, they have a seamless app experience with user-friendly interfaces thanks to the codes optimized for the software used by that device.
