Not impressed

I have the Angle Measure Tool and I thought this one could be better as it claims to have 8 tools.
First open, I see 6 tool buttons, one of then redirect to a website. This was the first disappointment, the ads for a paid app.
Then one tool, acoustic db levels hat buttons in German language and did not even work.
Also the app itself has graphic issues with buttons too big, compared to the other tool.
I would like to keep it but those, especially the ads or the link, are deal breaker. Very disappointed.
