XYO.net and doing App Marketing Research

I have been doing ASO for the last 6 months almost full time and I’m always looking for different tools, sites, resources that can help app developers to VISUALIZE and understand a bit more their market before they work towards developing their app. In many occasions I believe if an app developer had the time to understand their market, the app store they are targeting, they could avoid some painful mistakes.
So today we have XYO.net, easy, fun and very easy to find and search apps. Clearly XYO is build for end users (the app user) but for App developer is a fantastic tool to understand a bit more the market they are trying to conquer.
