I apologise if this was aksed and answered before - I tried searching but to no avail.
Does the Renshuu iOS App have an url-scheme that can be used to open the app from other apps like Scriptable, Widgey or a link in a browser?
As an example - Lingodeer registers 'com.lingodeer://' as URL-Scheme and if I type that in Safari it will open up Lingodeer. This is incredibly usefull if you want to allow launching an application from things like a Widgey Widget or from tools like Scriptable.
In the likely case this isn't possible (yet), all that would be required is this little bit in the Info.plist of Renshuu which would allow anyone to open the application using 'org.renshuu://' as URL-Scheme:
Neat idea. Would it still be possible to use the website using safari if this was implemented?
Oh yes absolutely - it doesn't interfere with the https:// Address in any way it simply tells iOS "If someone wants to open an URL that uses 'org.renshuu://' as Protokol then the Renshuu app can handle this" and then opens the app.
A lot of apps also parse whatever URL parameters the user passes along and allow apps to interact that way (for example see the URl-Actions Fantastical offers)
It's an interesting idea, and something I may be able to implement in the future. This is the first time I've had a request for something along these lines, although to be honest, I'd like to see more visible requesting for something like this before I put time into implementing it.
