App seems to work like a charm. It’s just very unfortunate that I was immediately charged EUR 18 after selecting a monthly instead of a yearly plan.
The monthly plan suited my situation better. I was very keen on trying out its features for some projects in and around the house, but apparently free trials are only included on the yearly plan. Misleading and unnecessary. Apple won’t refund my purchase. As mentioned the app works fine, I just don’t find it reasonable to be charged EUR 18 for trying it out for a month when a free trial option is advertised.
