The Telegram app for iPhone and iPad has been updated to introduce new related content such as reactions, translation, hidden text, additional interactive Emoji, and provide users and channels with thematic QR codes.
Reactions
As the response increases, users can now double-click an information bubble, and a small thumbs-up emoji will appear at the bottom of the message. You can change this quick response emoji under Settings> Stickers and Emojis> Quick Responses in the app. For more reactions, tap and hold an information bubble.
Hidden Text
Similar to the invisible ink option in iMessage, Telegram now provides a spoiler format for hiding text. When entering information, select the text you want to hide, click B/I/U in the black pop-up menu, and then click Spoiler. Messages sent in spoiler format will appear blurred in the chat, and you can click on the message to display the hidden text.
Translation
Telegram now provides the ability to translate any information into another language, right in the app. Translation can be enabled under Settings> Language in the app, and then you can tap and hold a message to translate it into your language. You can also exclude any language you speak fluently and hide the translation button for this information. On iPhone and iPad, this feature requires iOS15 and iPadOS15 or higher.
Theme QR Code
Another new feature is the ability to generate themed QR codes for any user with a public username, as well as groups, channels and bots.
Interactive Emoji
There are additional interactive emojis that can be animated when sending, such as fire emojis and crying faces.
