If someone starts now with Agenda, but does not buy Premium, but only in three years, then he gets practically all Premium functions of these three years for the price of 35 euros. Someone who has bought the Pro versions every year from the beginning of these three years has then paid at least 105 euros for the same Premium functions. Is this correct or a mistake in thinking on my part?
This is correct, but of course those who bought the features 3 years ago have already been able to use them for three years, while the other person didn’t. It’s a bit like arguing that somebody buying an iPhone 13 gets so much more for his money than those who bought their iPhone 8 a few years ago and now wold have to pay much more money to also get an iPhone 13.
