There seem to be 3 spreadsheet apps in the store. A couple seem to have had teething issues. Has anyone tried them out lately to see which one currently works the most reliably?
If you read the reviews, all of the spreadsheet apps seem like crap. plain and simple. I myself am waiting for Mariner Calc for iphone which is currently in beta testing. It seems to be the most promising. Here's the link:
MobileFiles Pro works very well for me. It has its limitations, but it's user friendly, functional and stable and does wifi transfers as well as MobileMe uploads/downloads.
At least iSpreadsheet is buggy. Google Docs synch does not work as advertised, it is just upload and download plus there are strange error messages, but the files are uploaded nonetheless.
