Why would you need Android App?
Android is Google’s operating system and it dominates the smartphone market with more than 2 billion active users per month. Because its noticeable difference between two major operating systems, it is reasonable to develop same apps for Android separately from iOS.
Most famous companies that develop devices that use the Android system are Samsung and Huawei, followed by LG, Xiaomi, and others. If you decide that your targeted customers are mainly Android users, there will be no problem at all, because we make Android apps too.
