Bookly is compatible with the vast majority of WordPress themes. As long as your theme is developed according to the WordPress Codex, it is most likely compatible with Bookly.
While we cannot test all themes individually, incompatibility issues have been rather rare in our experience.
To ensure compatibility with your theme, we recommend trying to install the free version of the Bookly plugin. If the free version works with your theme, then the Bookly PRO version will as well.
If you encounter any compatibility problems, please don't hesitate to email us at support@bookly.info. We'll be happy to assist you.
