No Excel, stake toys

[Malanno0]

Hi, I've got a Macbook and I don't have excel. I'm registering my trades on stake toys and it seems a good tool to me, but do you feel like something it's wrong in this way to register my trade. If you never heard about it before it's a website where you can save your trades for free. What's can be a big thing that this website miss compared to an excel sheet?
