Thank you for the feedback. The arrow selector was added to help reduce typing mistakes, but I understand it can feel slower when you already know the code. I’m looking at adding direct typing as an option in a future update.

At least the dev has started to look after his app again. Two stars off for no changelog!

Do you like the content? I apologize, but I focus on the content of the app and not on app change logs.

Got the pro a few years back, then it simply crashed on every single phone once you got the code up. Now it's even worse - it's full of adverts - even for the paid version which are incredibly intrusive. Then - and I just can't get my head around this:- it asks you for money and tries to forward you to your Google account! Absolute turd!
