I had the option to get a membership that I could expense through my work, but decided against it after the trial period ended.

The reason was entirely the terrible state of their app.

- Random crashes, or times when it would not start up at all.

- Text to speech is unusable because it cannot start reading at a specific point. Only at the beginning.

- Cannot download epub to use with a different (better) epub reader.

So even though it would not cost me anything, I realized I would never use it due to the issues with their app.
