One more tip: this probably applies to Android as well, I’m not sure as I haven’t used it extensively. But iOS has very good, deep, system-wide autofill.

Make sure you have a contact card in your contacts marked as you (“My Card” at the top of your contacts list) and populate it with all the phone numbers, emails, and addresses you can think of. Tag them all properly (work, home, secondary, etc) and even add usernames and whatnot, go all out.

iOS will use those details to autofill signup flows in many apps and services, as well as autocompleting stuff like “my address is” and “my phone number is”. Saves a lot of time.

It also has deep password manager autofill integration. So you can enable your favourite 3rd party password manager as the system autofill and you can call it up even in apps to create new logins or retrieve saved ones.
