There is a feature called URL Scheme which opens other apps. But there are limitations of using this on other apps too. So you need to 1. check if the app you want to open supports URL scheme or not, and 2. see if it works on GoodTask. (If not, let me know details)
I did find info on URL Schemes but didn’t see how it applied nor a clear example (for opening apps). I’ll look at this more but if you could illustrate with an example I’d appreciate it.
URL scheme is a link that can be opened like web links from Safari and other apps. For example, to open GoodTask, you can type goodtask3:// in Safari and it'll open the app.
This is brilliant @Balaji. I have this running now. As it happens the app I wanted to run doesn’t have a URL Scheme so the shortcut URL Scheme was exactly what I needed, and it works like a champion!
