How do I add partner to pregnancy apps?

[AlreadyThere]

Hi all. I am 5+4, first pregnancy (37F). I have previously heard my friends saying their partners receive emails and notifications from pregnancy apps like baby centre and others. I am not announcing until after 12 weeks so I can't ask them.
I have downloaded pregnancy ++, Ovia and Baby Centre. On ovia I managed to add DH's email but he hasn't received anything- I thought he would receive a link or something. The others I can't find the option to add a partner and share content with them? Please help.

Why don't you ask him to download one or two of the apps?

@WanderlustBaby he has downloaded them. But unless he logs in with my credentials he has no way of keeping up. I thought they allowed one to share info with your partner such that they use their own credentials and can get notifications if for eg i update hospital dates or symptoms.

Couldn't you just tell him when your appointments are, or add them to a shared calendar? Are partners allowed to attend appointments with you now?
