Consider the scenario where I have fever and someone pings me - Just checking up on you if you are fine
Is the reply - Thanks for checking in. I am good now correct. I am mainly confused about the use of checking in is that even a valid English sentence. Any better way to express the same.

  • We can probably offer a better answer if we have a little more detail. What is it about "checking in" that concerns you?

  • The concern is if it's proper English. Grammatically correct Apr 2, 2021 at 18:07
  • I don't see checking-in as a proper word in online dictionaries Apr 2, 2021 at 18:14

Yes, it's a valid sentence.

It comes from a phrasal verb check in which means (#5) pay a short visit, make a phone call to see how someone is doing .

I just wanted to check in after your accident. How are you recovering?

My son checks in regularly with me when he's travelling.


To check in is to report your presence to some organisation that is expecting you; for example, at a hotel where you have reserved a room, or at the airport when you have booked a flight. It is not the same as checking up on someone (asking if they are OK).

You might answer "Thanks for checking up on me", "Thanks for enquiring", or "Thanks for getting in touch".
