I am not a Tidal expert by any means, nor an Apple expert, but here is what I know.
I think Web app means browser based apps. If you access Tidal through a Web browser, you have to use Chrome for CD quality.
The desktop app for Windows does HIFI, I believe.When I go into Settings - Streaming it lets me choose the quality of the output. On the desktop app, HIFI is an option. HIFI means CD quality. When I use Firefox to access the Web application, it says I cannot choose HIFI and only gives me Normal and Hi, which are not CD quality.
The problem with the Tidal app for me is that the app then uses the WIndows audio system, which is not bit perfect. I am not sure how that works on Apple. Give it a try and see if it gives you the HIFI option in Settings - Streaming.
The issue with using the tablet or phone apps is getting the output to your stereo setup without using the DAC in the phone or tablet. The Android Tidal app does not let me send the HIFI signal to another system. So, I use UPnP on an Android device since it can pass Tidal CD quality files to a DLNA renderer for playback, in my case the JRiver renderer on my PC.
Unfortunately, I do not know how to use an Apple tablet or phone to send that signal to an Apple system. However, the latest Tidal app for tablets and phones says it supports Chromecast. So, if you buy a Chromecast Audio device, you should be able to stream a HIFI signal to it and use the Chromecast Audio optical out to send the signal to a DAC, if you DAC has an optical input. Otherwise, I do not know how to send the HIFI digital signal to from the phone to an Apple desktop or laptop.
Again, I am no expert, but that is what I understand.
