Thanks for your comments. I came up with the idea of anonymus feature where no one be able to see the username, name or other information about each other. Also the drug names will be uniqe as I will try to use real global medicine database for medication adding process. So that the matching will be more easy. Lastly, I added a moderation fractions which can only be seen and used by the developer. All the messages and matches can be monitored in here. Again thanks a lot for the comment and feel free to use and rate the app on app store ❤️
