> forever to launch
I cold started the app just now. It takes less than half a second to get me into the book after showing me the cover art of the book. It’s about the same as any other app on my phone. Certainly doesn’t take “forever”, although I concede my phone is about a year old. It could be different if you’re using the app on a much older device.
Seems harsh to call it a “pathetic joke” or “frankly garbage”. I was just reading a book on my phone so I checked the “laughably few display options”. I see the ability to customise font (8 fonts, serif, sans-serif, dyslexic friendly), font size, page colour, the option to update page colour according to system theme, line spacing, alignment, orientation lock, continuous or page scrolling and 8 other options.
It’s better to say that your specific need to change the font colour isn’t catered to. But there’s no need to talk in such harsh terms. Get a hold of yourself.
