This is an excellent app but it can be better. The developer has done a terrific job considering WhatsApp hasn’t put this out for us using Apple Watch and is improving it quickly. Notifications are done through Apple Watch notifications and WhatsApp. Sure you can respond to a message this way but you can’t see an entire chat or prior message once you’ve responded. Using this app you can see a chat with pictures and recordings. You can see all of your chats and choose which to respond to. You can’t do that without this app. It is definitely worth the $3 and I’m sure it will get better. Give the developer time and suggestions. Refresh can be faster. Can notifications be better? how about when receiving a notification, having a button that takes you directly to the chat? Right now if I get a notification and I want to read the thread I have to get out of notifications and open watch chat to see the conversation and respond. Thanks.
