We currently have a feedback form to submit feedback and haven't gotten any yet through the form. We also have a dedicated subreddit at reddit.com/r/SubtleTV. Glad it's working now. iOS can be a bit tricky due to restrictions but we're working on improving compatibility as much as possible. Intended behavior for iOS is to open the native player and then let you skip to the next video from the native player. Once we have our iOS app it will be a lot smoother.

Yes your assumptions are correct. We're streaming from Youtube, Dailymotion, and Vimeo using our custom player and our API.

The suggestion about custom channels is a good one, currently you can watch specific topics by doing a search.
