The photo sharing site has rolled out the handy new tool, which allows you to pick the best time to direct message your pals.
They wrote in a blog post: "Today we're making it easier to connect with friends on Instagram by showing you when they're available to chat. When your friends are active on Instagram, you'll see a green dot next to their profile picture in various spaces within the app, including the Direct inbox and your friend list when you share a post from feed.
"You will only see status for friends who follow you or people who you have talked to in Direct. You can easily hide your own status and turn off the ability to see when your friends are active in your settings. DMing friends and connecting over the content you love is more fun when you know your friends are there to see it. This update gives you the ability to have more of those realtime conversations while giving you the control to hide your status altogether."
It comes after Instagram launched a feature that allowed you to video chat with friends in your direct messages.
They shared on their website at the time: "Now, you can video chat in Instagram Direct, either with just one person or a group. Video chat gives you the experience of realtime video in a private space and helps you feel close and connected to friends when you can't be together. Your friends are already on Instagram, and with video chat, you can seamlessly connect across iOS and Android and without a phone number.
"Video chat is perfect for groups. You can video chat with up to four people at a time, and the video will expand as more friends join. If there's an active video chat in a group thread, the camera icon will turn blue. Simply tap the camera to join in the fun. You can video chat with your friends for as long as you'd like. When you're ready to leave the video chat, tap the red phone icon at the bottom."
