Warum erlaubt Apple diese App???

Ich habe mir die Light Version runtergeladen und durch den Kauf von 1,09 € auf Pro upgedatet.
Ich melde mich morgen telefonisch im App Store und möchte mein Geld zurück haben! Bin richtig wütend!Diese App ist wirklich eine Frechheit.

Neat!

A nice little* app which functions exactly as it should, without clutter or complication.

*I like it; but I do wonder why it is almost 15MB.
