Hi Knowvio! I just recently bought the Physics X app for IOS. I noticed that on your website and on the description of the Physics X app, you note that the Calculus X app is free. I have been trying to download this app for free but unable to do so since the App Store states it to be $4.99. Is this app still for free? Thanks.

Hi AP Calc/physics student,

Thank you for your message! I am sorry about the confusion — this is my fault. The Calculus X was free for the first two weeks, at which point I wrote on the website and app description that it was free. When I switched it to $4.99 I forgot to change this. So, right now, the app is not free. In a few weeks, however, we will be releasing a new version of the app which allows you to download and access the first 5 chapters for free. So look out for that! In the meantime, I hope you continue to enjoy the Physics X app. Please let me know if you have any other comments. Thank you!
