DB Tool is a small application that allows you to make simple queries in your databases. For now, it only supports MSSQL and MySQL databases, and you can only make a select query, I hope that in the future I'll extend this. This application is developed for Android, iOS, and WindowsPhone. For now, it is completely free of charge because it is a pet project, not a commercial one. If you have any question or suggestion please feel free to contact me.
