Jibber Jabber publishes this site and makes the app it features. Our recommendation is not independent.
We write practical explanations and examples for learners. Examples describe common patterns, not every speaker or region. We do not convert listening hours into guaranteed language levels.
We use official product information for app features and pricing. We link to official exam bodies where exam details matter. Product terms and external resources can change; check them before you act.
Our curriculum uses editorial stage suggestions, not formal placement. Lesson times are estimates. We check the creator, topic and published text of each linked recording. We distinguish free audio from paid transcripts. Our questions focus on the specified passage and do not assume the learner has paid access.
See sources and the sources shown on individual pages. Where a product fact is not verified, we say so.
