Google Calendar - iPad compatibility I'm trying to install Google Calendar app on my IPad Air 2.

Couldn't find it in App Store on my IPad. So I found it on a web page
https://itunes.apple.com/us/app/google-calendar/id909319292?mt=8
then I sent this link to my IPad and App Store installed it on IPad but...
It was installed like for IPhone, everything was big and huge so i had to remove it.

It looks like there's no Google Calendar app for IPad. Am I right?

How to install Google Calendar on IPad?
There's no separate iPad version, no.

The iTunes Store Page you linked says compatible with iPad, but optimised for iPhone.
That's likely to mean it works, but won't look great.
