Received an .ods spreadsheet by email or in a messaging app and got a blank screen when you tapped it? ODS Direct natively opens OpenDocument Spreadsheet (.ods) files created in LibreOffice, OpenOffice and other office apps on iPhone and iPad — and now lets you edit them too. OPEN INSTANTLY • Tap any .ods file in Mail, Messages or Files to see it right away with the built-in Quick Look extension. • Or open it in the app for the full experience: sheet tabs, frozen row and column headers, pinch to zoom. • True to the original: colors, borders, merged cells, text styles and alignment are shown as the author made them. EDIT AND FORMAT • Double-tap a cell to change its value; formulas and formatting are kept when you save. • Bold, italic, underline, font size, text and fill colors, borders and alignment. • Insert and delete rows and columns, hide columns, number rows, adjust widths and heights — with undo. • Save to the same file or save a copy. • Create a brand-new .ods spreadsheet from scratch. HIGHLIGHT WHAT MATTERS Mark rows and values with the highlighter in six colors. Your marks are saved inside the file. FIND ANYTHING • Search every sheet of a file and jump between matches. • Search across all your recent files and the folders you add; each result shows its sheet and cell. AND MORE • Export any sheet to CSV. • Recent files for one-tap access. • Light, dark or system theme — colors adapt intelligently in dark mode. • English and Turkish interface, switchable in the app. • A sample spreadsheet is included, so you can try everything right away.

Verdict
The clearest difference is ads: ODS Direct at none against Instasign's shown. Instasign's advantage is update cadence (every 10 days vs every 2 months) and iOS requirement (13.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
