About this app

Cast to TV from your phone, with subtitles that actually show up. One tap plays any local video or photo on your Chromecast or DLNA smart TV. Subtitle casting is the one thing most cast to TV apps quietly drop; BubbleCast was built to get it right.

BubbleCast streams your local videos and photos (downloads, recordings, camera footage, screenshots) to your TV. Works with Chromecast and with DLNA-compatible smart TVs from Samsung, LG, Sony, Philips and more. Demanding files — MKV, HEVC/x265, DTS audio, embedded subtitles — just play.

Subtitles, done properly
• Reads subtitle tracks embedded inside MKV files and shows them on the TV.
• External SRT, VTT and ASS files supported, with a size slider and live preview.
• Blu-ray (PGS) and DVD image subtitles are blended into the picture.
• No subtitle file? Search OpenSubtitles from inside the app and switch tracks while you watch.

Plays the formats your TV can't
• HEVC, x265 and HDR videos are converted on the phone in real time and start playing in seconds. HDR is tone-mapped. No PC or server needed.
• Movies with DTS or TrueHD sound are detected and the audio converted, so a film never plays silent.
• Multi-language files show an audio-track selector (language, codec, channels). Switch tracks while playing.
• DLNA smart TVs receive the original file and decode it natively — 4K, HEVC and HDR stay untouched.
• Automatic recovery: rejected files, silent failures and stuck buffering fall back to a working path by themselves.

Photos on the big screen
• Cast any photo from your phone full-screen to the TV.
• Browse your whole gallery inside the app — tap a photo to display it.
• Photos stream straight to the TV; nothing is converted and nothing leaves your network.

Comfortable to live with
• Movie and show info with posters for your library.
• Resume where you left off, and auto-play the next episode.
• Seek on converted streams, with 10 and 30 second skips.
• A built-in connection check explains network problems in plain language.
• The app speaks your language: English, German, French, Italian, Spanish, Dutch, Polish and Portuguese.

Private by design
Your videos and photos never leave your home network — the streaming server runs inside the app. No account, no sign-up, no tracking, no analytics, no cloud.

Simple pricing
Casting, subtitles and photos have no limits. Videos that need real-time conversion play at full quality for 30 minutes per session; one single purchase unlocks unlimited conversion. No subscription, ever.

Good to know
BubbleCast plays your own local files; it does not cast websites or streaming services. Fire TV and Roku have no open casting support built in, so they are not reached out of the box — though a Fire TV running a DLNA-capable app such as Kodi will appear as a smart TV target. Requires Android 10+ and a compatible receiver on the same Wi-Fi network.
