No ads, no account needed.
Watch SDR video at HDR brightness. Browse the videos on your Mac or NAS by folder on your iPhone or iPad, and get the most out of your display. Motion goes up to 120fps.
- Browse your shared folders
Connect over SMB to Mac File Sharing or a NAS (Synology, QNAP and more) and play straight from the folder. You can also open videos from the Files app, your photo library, or a direct video link (.mp4 / .mov / .m3u8). WebDAV, Jellyfin and DLNA/UPnP servers are supported too.
- SDR to HDR brightness
Uses the extra brightness of your HDR display to make SDR video brighter and more vivid. Presets: Natural, Vivid, "Brighter, as is" and No conversion. A/B compare shows the original side by side.
- Sharper and smoother
Videos smaller than your screen are upscaled to its native resolution. Videos at 30 fps or lower can be smoothed with frame interpolation. Both pause automatically when the device is hot or in Low Power Mode. Up to 120fps on ProMotion displays.
- Anime upscaling (only when you choose it)
Choose Anime Super Resolution to sharpen anime such as DVD-quality episodes 2x or 4x with trained models on your device, or Anime (Light) for a lighter pass that cleans up line art. Uses trained models only when you choose it. Everything runs on your device and switches or backs off automatically to match its speed, temperature and Low Power Mode.
- Playback controls
Choose a playback speed from 0.5x to 2x. Set A and B to repeat a section (A-B loop). On iPhone, rotation lock keeps portrait or landscape. Double-tap to skip 10 seconds back or forward, press and hold for 2x speed, pinch to zoom. Import your own LUTs (.cube) from the Files app and apply them.
- Subtitles, audio, lists and PiP
Subtitles in the same folder as the video (Movie.srt / Movie.en.srt / .ass) appear automatically, and embedded MKV and MP4 subtitles can be selected. Switch between audio tracks. Folder lists show thumbnails, with sorting, search and favorites. Picture in Picture lets you keep watching while you use other apps (inside the PiP window, HDR highlights are more restrained due to iOS limits).
- Formats
MP4 / MOV / M4V / HLS / MKV / AVI (H.264, MJPEG and more). H.264 and HEVC (including 10-bit, HDR10, HLG and Dolby Vision 8.1).
