Better pricing tripled my app earnings

Better hosting can triple your visitors :-)

Perfect thanks ;)

How did this jump to top of HN in 30 minutes? The article is not of much use since it's just a marketing piece.

It's got a lot of upvotes and not too many comments in a small period of time.

you should use a smaller image at the beginning of the article, it's 6mb (5184x3456)

But it's only displaying small on my screen thus it must be small in size. ( I know it's css resizing )

That's because it has CSS resizing it on the browser (max-width).
