Open in a tap
Sheetio shows your workbook the way it was made, with sheet tabs to switch between worksheets.

Find anything, fast
Type a word and Sheetio highlights every match, then jumps from one to the next.

Headers stay in place
Frozen rows and columns saved in the file stay put while you scroll. Or freeze the header row yourself from the menu.

Phones and tablets
On a tablet, Sheetio uses the extra room to show wide sheets at a glance, with your recent files right next to the Open button on the home screen.

Private by design
Sheetio doesn't even have the internet permission, so your files cannot leave your phone through it.
