I downloaded the app assuming the titles they have in the adds were the lessons that I’ll find in the app. Wrong. It ‘s not about improving your public speaking. It’s random facts about topics (History, geography, science, etc). And you can’e even listen to the content, you have to read it. I don’t have time for that, or interest, so I cancelled. Guess whet. I was then charged a higher subscription level and when I asked for a refund they said they don’t offer refunds but offered me a BS workbook. I threatened that I will dispute the charge with my CC and they did refund it.
