Liked everything, but one issue. The read aloud changes the voice suddenly. The high quality and low quality toggle doesn't work properly. I can't listen to voice before setting it and my device heats up very much when using the read aloud feature. I didn't face the heating issue while using Google Play Books.

Loving the app so far! Clean simple design. Some nice quality of life features like finding your book covers easily. A healthy amount of customization although not extensive (I love the ambient noise). The link to audiobook or TTS is amazing too.

Easily worth 5 stars if it didn't pause 30 seconds after each paragraph. That makes it basically unusable but I feel bad giving this high potential, non-scammy app that was made with love and dedication a lower rating.
