What do the green circle √ and yellow circle arrows on the right side of Momo's chat message in the picture mean?

In Momo's chat, I sent a green circle √ the other party has seen it, and I sent a yellow circle ↗, but the other party has not seen it.

The green circle √ and yellow ↗ icons in Momo app can let both parties know the status of information transmission in time. Prompts such as "sent, read" can let users know whether the information is seen by the other party in time, and Momo can find nearby people through geographical location information, which is more convenient for real-time interaction with people and strengthens more real interaction.
