Typebell
Read full descriptionHide full description
Turn everyday notes into a writing ritual. Typebell brings the character of a classic typewriter to iPhone and iPad, with mechanical keys, moving typebars and letters that appear as they strike the paper. WRITE WITH CHARACTER Tap the carriage-return paddle or slide it to start the next line. Turn the paper-feed knob, choose a black or red ribbon, and adjust margins and line spacing. Enable automatic line return when you want to keep writing without pausing at the margin. Key sounds are optional. SPACE FOR YOUR WORDS Capture quick ideas, keep a journal, draft a story or write a poem. Switch to Focus for a simple text editor and word count. Create, rename and search notes by title or content. Use portrait or landscape layouts on iPhone and iPad, with support for a physical keyboard. EXPORT AND SHARE Save your writing as PDF, editable DOCX or plain text. Share a document or just the text using the system share sheet. Exports contain readable text rather than a reproduction of the mechanical page or ribbon colors. YOUR NOTEBOOK, ON YOUR DEVICE Notes save locally and writing works offline. No account is required. Typebell does not provide its own cloud sync. Classic keys. Modern notes. Your next page is waiting.
