One of the great things about Discourse as a forum platform is that there is a corresponding mobile app. This app lets you connect any Discourse-hosted platforms to your smartphone to create an app integration. You can download the app from the Google Play Store or the Apple Store and then get started. I have included some screenshots here from Android OS but I’m sure the process is similar if you have an iPhone. If you don’t want to download the app, simply bookmark this web address 
→ https://roundthecauldron.discourse.group
Using the Discourse App
– Download the app and select " + Add your first site"
– Type in the web address for the forum → roundthecauldron.discourse.group
– Select “Connect”
– Discourse will open the forum in your browser. Login!
– Authorize access.
– Then you can use the Discourse Hub App to quickly open the forum or create a bookmark on your home screen.
Let me know if you’ve got any questions!
