Read full description

Yonder displays your text in large, bold type across the full screen of your iPhone or iPad — designed to be read clearly from across a room. Whether you're holding up a sign, running a cue card, or prompting a speaker, Yonder gets your message seen. • Cards – Create cards with custom text, colors, fonts and styles. Every card is full screen, high contrast, and built for distance. • Decks – Group cards into decks and present them in sequence. Swipe manually, let a timer advance them automatically, or set a time for each card. • Teleprompter – Scroll mode moves your text smoothly up the screen at the speed you choose. • Flashcards – Flip cards to reveal presenter notes on the back — ideal for rehearsal, Q&A, or cued responses. • External Display – Connect to a TV or projector, wired or with AirPlay. Your audience sees the card while your iPhone shows your notes and what's next. • Apple Watch Remote – Control your deck from your wrist. Advance, go back, pause, and flip from your Apple Watch, with a gentle tap before each timed advance. • Lock Screen Controls – Pause or skip ahead from the Lock Screen or Dynamic Island while a deck plays. • Customization – Choose your font, color, alignment, and size. Enable all-caps for impact. Save your defaults for instant consistency across every card. • Import & Share – Turn text or Markdown files into decks, send text from other apps, and share cards and decks with other Yonder users via AirDrop, Messages, or Files. • Backup – Back up your whole library and restore it any time.
