Two more Naturedigger apps are now compatible with the iPhone X! You can download the latest version of Horseshoe SOS just in time for spawning season (below), and Knotweed! just in time for... "oh no it's knotweed season!"
If you haven't checked out either app, they are full of great information and photos and definitely worth a look. They are free with no in-app purchases.
