What's New in Chatwork

9.9.0

September 8, 2026

Thank you for using the mobile Chatwork app. The following improvements were made in this update. Improvements: - Incoming Chatwork Live calls now play the ringtone set on your device. - When starting a call, you can now choose from three options: voice, video, or waiting room. The waiting room appears only when you select it. Other minor display improvements have also been made. If you have any comments or requests for the app, please send them to us from the "Comments and Requests" section of the account screen. Thank you for your continued support.
