Publish updated website and update API calls in associated iOS and Android apps

Some backend changes were made to our website admin panel which controls the settings on our iOS and Android apps for our software. I want the updated website code installed on the server. Additionally, a couple of changes were made to the API calls that the apps use to interface with the website backend (and STRAPI database). The iOS and Android apps need to be updated to send the correct additional information in the API calls. Should be debugged and tested to make sure everything is working.
In addition, I want the website updated so it functions properly on mobile devices and looks good on them as well as on laptops or desktops. Website is www.smelltest.io.
