This is the question which will be popped on everyones mind on many stages of life. I am thinking about building an application which could be used by tens of thousands of people everyday.
After a long thinking I am going build a Instagram photo/video downloader tool. Which is both a web application supported with chrome/firefox addon to simplify things for the user.
Also one another thing i use these days is a password generator tool. Since there are lots of people signup for a webpage which they won’t even use for the second time, and many websites getting hacked. Input a random password is a much better way. So soon i will be building one of those. the same as the pervious one. But most of this one focus would be on firefox and chrome extension.
If you think i need to build some other things please let me know in the comment box. Happy Reading.
