Socialblade is fun when you maybe need a little 'pick me up' regarding your channel... but their predictions are not to be taken for fact. Their monetary predictions are almost totally off for our channel, and in the past two years they have shifted from predicting us at 100k subs in 5 years to 20k sub in 5 years back to about 120k subs in 5 years. Their predictions are based on the past, and change with the success/failure and overall performance of every video you post.
There isn't an app to make things searchable on Google... but you can rank for Google search the exact same way you rank for YouTube. It's more complex and more competitive (think of the massive amount of everything on the internet versus the smaller amount of content on YouTube alone). But you don't need to have a different ap. You can simply do what you are already doing for YouTube as far as trying to rank in search and some times you end up ranking in Google as well.
A note on ranking for Google; it is different than ranking on YouTube because it is more competitive, but also ranking for YouTube doesn't mean you'll rank on Google and vice versa. I have videos that rank on Google and have pitiful ranks on YT. It's simply about having the right metadata and the right content for an area that is underserved.
