Yomu is free to use. Every basic feature, setting or book format is available and lets you try out the full reader. An upgrade to Yomu Pro removes all restrictions and includes advanced features.

Your best way to support the app is to upgrade to the pro edition. It’s a single one-time purchase for iPhone, iPad and Mac. There is no subscription or any other recurring service fees.

Already purchased the pro edition? You can donate any amount via Ko-fi to support the app’s continued development. Donations are voluntary and do not include any additional features, services or content.
