Zero cost, zero sign-up
Open the app and start watching immediately — there is no registration stage at all.
Multiple server backup
If one link dies, OnStream auto-switches to keep playback smooth.
Trakt integration
Sync your watch history across every device you use.
On-demand requests
Can't find your movie? Request it directly inside the app.
Built-in subtitle support
Select a language straight from the player, no external tools required.
Favourites list & sharing
Save shows and share them with friends without leaving the app.
Tested safe
VirusTotal scanned with zero harmful files detected.

Is OnStream Safe and Legal to Use?
Safety: Yes — OnStream has been scanned and contains no malware.
Legal note: OnStream aggregates links from third-party sources; depending on your country, streaming unlicensed content may fall into a legal gray area. A VPN is strongly recommended for privacy and to bypass regional blocks.
Troubleshooting
If the app won't install, re-enable Apps from Unknown Sources. Buffering? Switch servers or restart your router. Subtitles not loading? Change the server and reload. A black screen on launch means cached data is causing a conflict — clear it from Settings → Applications → OnStream. Still crashing? Update to the latest version.
