Answer:
Beta Testing
Step-by-step explanation:
Since you already created a prototype then you should create an official Beta version and do a Beta Testing. If you want to make sure that the product meets your users needs then a Beta Testing is the best option. Beta Testing consists of a hands-on testing of the application and it is carried out by your potential customers. It is the pre-version of the final product. This type of testing helps you to ensure there are no failures within the system and the software. The most important part is that the user/customer can give a feedback to the company, for it to make any changes, if necessary, and to improve the product.
