I'd also love to hear your suggestions on those couple of apps. Last time i checked, proper apps either charge whatever they want to because of their monopolistic position(+ the cost of an Apple Developer Program to a hobbyist) , and free apps unclear if they even solve the problem are designed to harvest and sell almost everything you have.
Orion is a very rare exception in both of these cases but they weren't able to make uBO work
