How often it is that you find the need to send a message to yourself?

Maybe there’s a nice link that you want to check out later (but didn’t want to bookmark).

Maybe there’s a checklist item that you don’t want to forget at the moment (but didn’t want to open a checklist app).

What’s that ubiquitous app on hand that’s already there?

Email?

But you’d still be opening the app and compose a message to yourself.

Aha! The Messenger. Can you send a message to yourself? In Facebook Messenger, check! But in Google Hangouts, no check.

Google Hangouts – please allow sending messages to one’s self.
