Apple has added many new features to iMessage to make conversations more interesting. One of them is the iMessage app. There are many iMessage apps for you to install for your group chat, enhancing the experience with the group members. Below is a list of 6 iMessage apps for group chat.
Organization and planning application
Create a poll on iMessage
If you have a lot of options and want to get people's quick opinions without texting a lot, then Polls for iMessage app is for you.
Polls for iMessage is completely free, but all members of a Polls for iMessage chat group will also need to download the app to vote.

Google Maps
In addition to the familiar Apple Maps, Google Maps for iMessage group chats allows you to share your location with friends in group chats.
While the iMessage app doesn't allow users to search for and send specific locations, you can quickly share your current location in a chat, but both parties must have the Google Maps app installed.

GamePigeon
With the GamePigeon app, you can play various games with friends, one-on-one or in a group chat.
To start a group game everyone must join and play at the same time. If anyone leaves the game they are out.
Also, the game has to be played on the same device so you can't switch between iPhone and iPad mid-game.

Bunch Games
Similar to GamePigeon, Bunch allows you to play games with friends in iMessage. However, unlike GamePigeon, Bunch offers a wider selection of games with Flappy (similar to the previous Flappy Bird game), Draw Party, Hoops, Crazy Cards (similar to UNO), and Guess What.

GIPHY
GIPHY's iMessage app offers animated stickers and short audio videos, in addition to the option to send GIFs. Overall, GIPHY is a user-friendly iMessage app that outperforms Apple's app.
Bitmoji
If you love expressing yourself, the Bitmoji app might be a good choice. The app offers a variety of customizable stickers to enhance your conversations with just one tap.
Bitmoji feature simple designs and a variety of stickers, adding facial expressions and humor to conversations in ways Memoji can't.
