Cross Platform Syncing

If a person has an Android cellphone and an Apple iPad can that person sync Contacts and Email?

That is done through your email provider. So I have gmail, outlook, and ymail. All 3 work fine on my android phones and my PC which are windows based. I have all the emails on my phones and my PC’s. I have never own an Apple product, so it is possible it is different. But according to this you can sync them.

Yes, you can sync your Gmail content with the corresponding apps on your iPhone. For example, you can get your Gmail emails in the Mail app, and your Google Calendar events in the Calendar app.
