Big Fat Warning: do not proceed if you are not familiar with HTML and Javascript. This is not for the faint of heart and ‘end users’. It is work-in-progress by Chris to work around the iphone issue documented here (section ‘Does it work on my laptop/pad/mobile?’, note on iphone).
With that said, there is a way to run traj on an iphone, but it is a bit involved. First, it needs a bit of HTML containing Javascript on your server – find that HTML file here.
Next, you need to construct the link such that it uses that HTML file as a trampoline, here is an example:
https://blog.mah.priv.at/mah/windyredirect.html?traj?time=1T04:00&lat=47.104&lon=15.217&duration=120&start=true
Here is an example page containing this link. If you click this link on an iphone, the following sequence will get you to run traj:

(on all other platforms except iphone, clicking the link above will take you straight to windy running in a browser tab!)
Next, long-press the link displayed there, this will what will show up:

Press the ‘open in new tab’ option from the lower menu:

Now click the ‘Open’ button, and you are almost there..:

Wait a bit until traj has done it’s thing, and there you are:

VoilĂ ! traj on an iphone!
This is just a proof-of-concept that it’s possible and maybe some kind soul with an advanced degree in web hackery can pick up from here.
