Not working

Your service is great! But this app keeps showing me a message that says “Failed to load data. We will try reload”. Rebooting app/iPhone did nothing.

Completely unusable.😥

Could be Better

Good app for communication but constantly glitches taking away peoples user names in a group message. Also notifications is a nightmare in this app. You either get none or you get 500 messages for one group. Simply make the notification one window that displays how many messages you have missed (similar to iMessage). And have the badge number on the app display not just a 1 but how many messages you have missed. Also, NEED a way to hide certain messages or filter so you are only looking at groups. I don't want to see individual message tabs for each person I am friends with. These need to be fixed ASAP.

We use Chatwork in our business every day, all day. We are spread out all over the globe and work all types of hours. Chatwork helps us all stay on track and is simply a really solid tool. I tell everyone I can about it. It acts as a repository of every piece of information for any project/order/customer communication and more all in track and in a quickly searchable interface.
Well done and thank you, keep it up!
