About
Kalem is the most practical way to open, edit and create UDF documents on your phone. Manage your petitions, contracts and correspondence in a Word-quality page view, without needing a computer.
Important notice: Kalem is compatible with UDF (UYAP) files. It is not an official app and is not affiliated with the Turkish Ministry of Justice.
WHAT YOU CAN DO
• Open, edit and create UDF: Open UDF documents from Messages, email, the Files app or the "Open with" menu in one tap. Edit the text or create a new document.
• Word-quality page view: Documents are shown as real pages with their margins, fonts and line spacing. While reading, text can also reflow to the screen width.
• Accurate tabs and hanging indents: Tab stops, indents and hanging indents are preserved as in the document. Adjust them with the ruler, just like in Word.
• Signed documents: Open electronically signed documents and view the signer details. Note: if you edit and save a signed document, its signature is no longer valid; the app warns you beforehand.
• PDF and DOCX export: Share your document as a PDF that matches the page view exactly, or as an editable DOCX.
• DOCX import (Premium): Bring your Word documents into the app to edit them as UDF.
• 13 ready-made petition templates: Start from common petition and correspondence templates, fill in the fields, save and share.
• Turkish-aware find and replace: Quickly find and replace text with search that respects the İ/ı and I/i distinction.
• Formatting tools: Bold, italic, underline, alignment, lists, color, tables and images. A scrollable quick-format bar sits above the keyboard.
• Works offline: No internet connection required.
