What the current beta does
- Plays the formats a system player refuses, on a libVLC engine.
- Browses SMB, NFS, SFTP, FTP and WebDAV shares in the app — no mounting, no Finder detour.
- Finds subtitles online by content hash, so a renamed file still matches.
- Takes your subtitle languages in order — Simplified Chinese, then English, then whatever you put next.
- Scrubs against a filmstrip of real frames, with chapters and thumbnail previews.
- Keeps a library with artwork, resume points and recently played.
- Handles live streams with a rewind timeline.
- Opens several playback windows at once on macOS.
- Picture in Picture, per-track audio and subtitle delay, secondary subtitles, A–B loop, speed control.
What it does not do yet
- Not on the App Store. TestFlight only, and it is a beta in the honest sense.
- No sync between your Mac and your iPhone. Libraries and resume points are per device.
- Assrt subtitle search needs an API token you supply in Settings — the quota is per token, so one shipped with the app would throttle everyone at once.
- No promise of any of the above changing on a date.
