Competitor tracking applications

Hi folks,
I have a question for e-commerce managers or owners.
How do you track your competition? Do you follow a manual methodology and visit their websites and fill out excel sheets or do you use any software to do that?
If you are using a software which one do you use and why?
We are currently building Prisync, prisync.com, a competitor tracking SaaS. We are based in Istanbul, Turkey and looking for feedbacks from the market.
Looking forward to hearing from you,
Burc
