Shame

Unfortunately does not work only crashes when trying to open

Not worth my money

Still under development, not all advertised features ads available, difficult to understand, navigate etc. You cant understand what you’re seeing so it’s pretty, but worthless.

Monad - what happened??

This used to be an interesting and useful app. Now it crashes on loading, again and again ( iOS 16.7.x)?
Please fix.

Great clock but

Really needs option to advance time clockwise. CCW doesn't work for me.

App crashes on loading

Can’t review this (and I want to given what I read about it) as it crashes about 5 seconds after opening. There’s the opening screen and then as soon as the next screen comes up it crashes.
