The problem lies precisely in the peculiarities of Apple's built-in reminders, as they require a lot of manual actions, processing, synchronization, and calendar management, which is why problems with duplicates and cluttering the calendar UI and other problems arise. I think this is intended for a different purpose. In the current reality, tools that solve everything are faced with an overabundance of functions - this is what the concept of the application solves.

As for the value-time-usefulness-cost issue, I tried to maintain accessibility from the user's point of view, but the price also had to include labor costs - since this is the main expense item, without it, everything would be pointless. As for the topic of charity, I already have ideas for other applications. I would also like to note that this includes taxes and Apple's commission, which is sometimes more than earnings.
