The public iPhone beta is being prepared.

Library

Different inputs. One visual language.

4789 starts empty. Add only the catalogs, lists, and files you choose. Everything arrives as the same browsable library instead of a collection of unrelated service screens.

Compatible catalogsAdd manifest or install URLs. No provider password form appears on the website.

LetterboxdEnter a public profile to bring its lists and film activity into 4789.

MDBListBrowse public collections and import the lists you want to keep close.

Files and downloadsImport local media, keep completed downloads, and return to them offline.

Discover

Choose a shelf. Search directly. Or wander.

Home keeps Continue Watching, collections, release tracking, local media, live television, and the sources you added within one composed view. The Wall turns those catalogs into an expanding field of posters when browsing is the point.

From title to play

Known facts stay visible. Unknown facts stay unknown.

Open a title to see context first. When you are ready, 4789 shows the playable options returned by the compatible services you connected. A ready option can lead; the full source view remains one tap away.

A 4789 title page showing multi-provider ratings — Detail keeps ratings, reviews, seasons, cast, and recommendations with the title.

The 4789 source view showing quality, size, codec, and known provenance — Sources show quality, size, codec, readiness, and provenance when available.

Player

Made for watching, not merely opening a file.

The in-app player keeps its most-used controls direct and lets the rest stay nearby without covering the picture.

Audio and subtitles

Choose tracks, search for subtitles, adjust timing, and change text size, font, color, and position.

Playback control

Seek quickly, change speed, fill the screen, inspect playback, and switch to another source.

Keep it moving

Continue in the background or use Picture in Picture where supported. Open in another installed player when you prefer it.

Watch later

Download a selected source into 4789, track its progress, and play the saved file without starting over.

Picture in Picture still needs a physical-device public capture. The audio demonstration fixture contains no real media tracks and correctly shows none available.

Files and downloads

Your own files belong here too.

Import from Files or iCloud, match local media to its title, and keep downloaded films and episodes inside the same library. Completed downloads can play in 4789 or open in another player.

More to find

Useful depth, kept out of the way.

Regional cinema catalogs, release calendars, a world map, Cover Flow, and appearance themes are there to explore. None of them interrupts the central path from library to title to playback.
