This is a good topic @vaibhavmule.
The 3 apps I regularly use for Productivity:
I use this app to take instant screenshots and they will be automatically converted into our branded short URLs (powered by Bitly), like this: http://s.pradee.ps/ogMf
We also have the option to edit the screenshot, add annotations, and save it.
We have multiple Twitter accounts for our brands, so Tweetbot is quite handy, the best part is, they automatically convert original URLs into our custom-branded short URLs.
3. Safari (Private Window)
In Google Chrome’s Incognito mode, if I open Facebook on one tab, then my next tab will also have access to Facebook, whereas, in Safari, I can open another Facebook account, it’s the same for Twitter and other portals. In this screenshot, we opened multiple Bitly accounts.
