I currently am using DocsToGo but am looking for another app similar to it: does Word/Excel editing and has password protection capability. I keep having an error with DocsToGo spreadsheets that say I've exceeded the limitations of the worksheet even though I haven't. And I found myself on vacation with no access to this particular spreadsheet. I've been checking around and Pages and Numbers are mentioned frequently but that there is a problem with the password protection not working at the iOS level. I welcome any suggestions and thanks to all for any help you can give me.
