App is retarded! Can't use it because the ad is covering the start button on purpose. Disconnecting from internet does not remove it and even crossing out the ad still doesn't remove it. Why developers? Why?
It's a scam Developer deliberately hides the start button with an advert in the hope that you will click it. Also, plenty of fake 5* reviews.
Excellent It is very good learning tutorial for who knows Basics of HTML and CSS awesome it is very useful to any kind of developers.
Worst app I suggest not to download
This app Doesn't work
