Which spreadsheet app do you for seo?

Which spreadsheet app do you for seo? On Android or iPhone.
I am looking for app with great native ios or android functionality for working with spreadsheet.
Microsoft excel sucks on mobile overall Microsoft and all its apps sucks on mobile , it has already discontinued its cellphone few years back.
And google spreadsheet will spy on your site and backlink data so its a non starter for blackhat
