This is a great app to have on your iPhone!" ― WHAT IS IT TransKey is a keyboard extension that translates your messages inside any app (like: WhatsApp, iMessage, Facebook, Twitter X, Email, Chat Apps, SMS, and many more). TransKey also works the other way around. Copy the text you can't understand and TransKey will show you what it means in your native language! ― HOW DOES IT WORK Write what you'd like to say, but before sending your message, tap and hold the Globe key to switch to TransKey. After selecting a target language, tap "Translate text" and watch your message get translated right in the app! If you'd like to translate a message you received, tap and hold it until an option to "Copy" appears. In TransKey tap "Translate copy", and the translation will appear in the same place!
