Good, but slow
I was writing my own pomo timer app, but found this app. Functionality is great, but after a day of use (on Big Sur (11.2.1)) it's using a lot of resources (CPU 90% ). I noticed that Metal is being used, a framework for low level hardware acceleration for rendering. I think its used to show the basic animations. Im not sure if there are memory leaks or that metal is not being used correctly, but for such a simple app eating up more than 1% of CPU is too much.
