Sorry, the Mooshimeter app isn’t tested at screen sizes that small. I just looked up Galaxy Pocket 2, it’s 320×240. The Galaxy watch is 320×320. I thought that all the sizing in the app was done relative to screen size, so I am surprised to hear that the sizing is completely wrong. Is it possible for you to post a screenshot, or send it to firstname.lastname@example.org? It would help to diagnose.
