Great little app but why no complication?  I would love to have it on my watch face.

### 4/5 — Perfect watch app for making conversations

This app looks great and works great as well. I do hope to see some improvements such as remembering the last used units and for the app to fill the display on the Apple Watch Ultra 2.
