1. Survey Monkey
I love survey monkey, it is exceptionally good platform to create your survey and share with your prospect/client etc. You can use that service to create a survey of 10 questions absolutely free but if you think 10 questions aren't enough, you can purchase the paid membership plans too.
I personally share with my every client who is going to indulge in any business in order to do the market research.
2. Wonderlist
Best to-do list management app I ever came across and personally used. This is very simple with good interface to organize to-do lists on the go and even synchronize them with your partner/manager/wife etc using free Wunderlist account. View and modify your tasks on Windows, Mac, Linux,iPad, Android and the Web. Hundreds of thousands of people worldwide use Wunderlist everyday.

6. Portable Apps
As living in internet and fast paced world it is necessary to become fast and even faster but if your system is not fast enough you can't be fast enough.
