You can use it, on all devices, using your Gmail.
The advantage of this application, what I like:
is the ability to use it anywhere, with the same account.
I use it when I'm not at the PC.
I get an idea, I'll write it on my cell phone if I'm not at home.
I can also use them on the Tablet.
I find it at home, on the pc. I just need to copy and paste afterwards.
At home I copy everything on Scrivener.
I can write, whatever I want, insert photos, shopping lists.
