Apollo is a superb Reddit client and one of my favorite iOS apps from last year. Unlike the official Reddit app, Apollo can't automatically open
reddit.com URLs1, so these URLs open in Safari if the official app isn't installed. However, there are a few easy ways of opening them directly in Apollo.
Copy URL to clipboard
If you copy a Reddit URL to the clipboard, then launch Apollo, the app automatically detects the
reddit.com URL and asks if you want to open it. It's a few taps and swipes, but it works fine.
Reddit URLs can be opened in Apollo through the use of an action extension workflow that replaces
apollo://. Sharing any Reddit URLs to this workflow automatically converts the URL and opens it, launching Apollo.
Both of the above options are quick to do but involve a couple of steps to complete. Opener ($1.99) is a useful app and action extension that allows you to open links in any app that supports it.
The benefit of Opener is that it can be set to auto-open URLs with compatible apps. For Reddit URLs, I've configured Opener to auto-open them in Apollo. If I have a Reddit URL, I can just tap the Share button and select Opener, then Apollo launches automatically.
