I Can't View my Hikvision App when I'm off my wifi

Double check that your setup of the remote viewing is done properly: Refer to this - https://securityaustralia.com.au/faqs/can-use-hik-connect-set-remote-viewing/ Otherwise, it may be that your modem is blocking some of your required ports. Below is a list of ports required to be open.
80 HTTP access – only allow if you plan on accessing the recorder through a web browser.

443 HTTPS port – as above with SSL

8000 – Server Port - required to be opened for all types of remote connections to a Hikvision device. Without this you cannot connect to the machine at all.

554 – RTSP Port - required to be opened for all types of remote connections to a Hikvision device. Without this you can not view streams.

9010 – Hik-connect port – Required if using Hik-connect accounts
