Many people have noticed that many well-known apps, especially social apps, have two-letter names, such as WeChat, Momo, MiLiao, Laiwang, etc. But in fact, if the name is longer, 3 characters, 4 characters or even 5 characters is no problem. For example, Mobile Manager and Baidu Maps are 4 characters long, Sogou Input Method and Alipay Wallet are 5 characters long, and ICBC Mobile Banking and 360 Mobile Guard are longer.
Of course, I suggest that the APP name should not exceed 5 words. However, it doesn’t have to be short for the sake of being short. The two-character name may also be an unusual combination or a difficult pronunciation. The key is to be catchy, easy to remember, easy to find, and easy to spread. For example, although Sogou input method has 5 characters, it consists of two parts: "Sogou" and "input method", and neither part is indispensable. Although this name is a bit long, it is easy to remember and will not impose a memory burden on the user. Therefore, there is no need to shorten the name deliberately. Of course, if the APP name is long, it does not necessarily need to be written entirely on the LOGO.
