The site doesn’t make it clear, but it’s not available worldwide. The App Store doesn’t tell you where exactly it is available, but it’s not in the UK.

This surprised me seeing as one of the example images shows Europe, including the south coast of Britain.

From website's FAQ:

Acme is currently available in the United States (including Hawaii, Alaska, and Puerto Rico) and Canada.

In Canada it's $35/yr and I don't see any indication of the 2-week trial that's mentioned on their website. Probably can still cancel within two weeks, but it simply has a Subscribe button before you can do anything.
