I've been using this app for about a year. I love the simple and useful functions. Black backgrounds, volume button page turner and linking references. I just never got a hold of the name and the icon of the app. The name has completely nothing to do with anything other than our reading is powered by lithium batteries, duh. The icon does not fit anywhere, I'm not sure if it's the strong colour frequencies radiated from purple or that it's just simply ugly. You need a facelift.

it's a nice app for reading epub with many settings and a good library to manage books. the only problem I had was with the images getting stretched (usually so much height in proportion to the width) but I really like this app and recommend it to everyone. I hope you fix that problem even though it doesn't cause much problems.

Really nice app! Though it'd be better to have more darker colors when highlighting (in dark mode.) So we could see the white text better, but that might just be a premium feature. It would also be better if we could reorganize (move) the categories around and also have a separate screen for the categories so we can see them all without using the side bar.
