Beta Version means trial mode. There are many applications that are without a trial version before. Be it mobile app or computer software. If there is any problem after making an app or software, they are released without beta version to be tested by the user. If any errors are found, users report them to the developers so that they can fix those issues . Since beta versions are released in testing mode , paid apps or software can also be used for free at that time. In fact, we use them to help app developers . So that they can fix the problems found. Since the beta versions are in test mode , the app developers usually do not take responsibility for any damage to the device. However, the possibility of such damage is very low. Hopefully I have been able to give you an idea of what the Beta version is and why it is used. Thanks!
