We have 2 apps currently available on our Android Google Play store and these are VideoScribe Now and Tawe. Please make sure you are downloading and using one of those as previous version of the app have been discontinued as Mike has mentioned.
If we have an old YouTube video up somewhere apologies for that, if you can post the link I'll make sure it's removed quickly.
Thanks for the link Aya, we've gone ahead and asked for that to be taken down by YouTube and I've edited it from your post.
The Android version of VideoScribe was something available for a very brief window of time due to multiple problems. You can't get it from us anymore, we don't officially support it and I'd be very concerned about the security of any links to there might be online before we can remove them.
