We don't currently have account tracking history (viewed videos, podcasts listened to) synced between the mobile app and the website, but we hope to make history for both platforms integrated eventually.
In the meantime, we recommend rewatching website videos on the app, since the app features annotated elements now built into each video. Videos are also strategically placed throughout the app Skills and Torah Journey content.
And any resource can be marked as as previously viewed/listened to by marking it as 'Played' on the video or podcast episode option menu.
