User Experience


Following best practices for Android app development, the design focused on creating an intuitive and accessible user interface. Special attention was given to the effective use of the thumb area, ensuring easier interaction with the app’s features. This user-centric approach aimed to minimize the learning curve and enhance the overall user experience.



Mobile Dialer was officially launched in 2022. The marketing strategy targeted B2B customers, highlighting the app’s robust communication features and ease of use.
