Maybe it connects better - I have a 70d and the connection process is annoying. Iirc it's WiFi direct but you have to connect and manage it yourself, and your phone will get cross there's no internet and disconnect you every so often.
My main camera now is a 90d which uses Bluetooth to connect first and then setup WiFi. Much easier process that makes the app much more useful. Although I've actually got an "unleashed" device that uses usb and hdmi for control, lets you do ramped time lapses and connect multiple cameras. No live view, but I can connect to both the 90d and 70d very smoothly which is more useful in general.
I looked at the canon app on ios, and they have continually eroded all your privacy.
At first, you could give it limited privileges to add photos from your camera to your camera roll.
But updates changed the app, so it refuse to work unless you give full access to every photo on your phone.
this is why we need alternatives.

It is used for DIY book scanners.
Instead, I have a shutter release pedal, connected via a 50 foot audio extension cable, to the wired remote port on the camera. It's not compact or elegant, but it's easy, fast and reliable.
I kept a set around with cables for my Nikon D700 and D7000.
If they use PTP-IP, you can do quite a bit.
It is ridiculous that such simple functionality is locked up.
Cascable is said to be better on iOS for Sony but I think you need the pro version for certain features; then again it can also do wired tethering with USB-C which is IMO more practical.
Never quite understood why (considering the A7II, for example, is an Android device!!) they didn't make that port a USB-OTG setup and make the shutter release a proper USB peripheral. But they didn't.
