Is there a off the shelf style mobile app that works with Events Calendar? Shoutem use to in an older version (i am told) but have not kept the feature as software versions changed from both companies.
At this point, we actually have mobile styling baked in – so in most cases you need do nothing but activate the latest version of our plugin 🙂
If you hit any difficulties with this please do create a support thread either here on our PRO forums (if you have a valid license) or else across on our wordpress.org forums.
