Created a Platform for Maths Help!

Hi guys, I've had a quite a good idea to create an app, specifically for Maths help, which can be accessed at http://app.bubblemaths.com/ There will always be people on that you can send problems to via your phone and they will respond live with help. Best thing of all, it's all completely free and there's no sign up process, just enter a username

did you create the app yourself and if you did want coding language did you use?

I created the app using JQuery, php and firebase - by google, took me just over a day to make

took you just over a day!? and also do you have to pay money to host the site, and also are you going to introudce ad revunes?
