Your Phone Is Now a Live Broadcasting Studio
Castream 4.0 is a landmark update that transforms your iPhone into a fully-featured live production environment. Everything you need to produce professional-quality streams is now in your pocket.
Picture-in-Picture (PIP) Camera
Use your front and back cameras simultaneously. Position the PIP window anywhere on screen and resize it to fit your production style — perfect for reaction streams, tutorials, and multi-angle broadcasts.
Draggable Overlays
All overlays are now fully draggable. Move text, graphics, and other elements around your screen in real time during a live broadcast to create dynamic, engaging layouts.
Lower Thirds
Add professional lower thirds — the name cards and title bars used in broadcast TV — directly to your stream. Perfect for introducing guests, showing your name, or displaying titles during segments.
Live Location Overlay
Show your audience exactly where you're streaming from with a live location overlay. You can use your actual GPS location or set a custom location for privacy or creative purposes.
Camera Filters & Voice Effects
Expanded from the experimental stage in 3.2: camera filters and voice effects are now a core part of the streaming experience. Add visual styles and voice modulation to enhance your broadcast personality.
Improved Chat Overlay
The chat overlay has been redesigned for better readability and aesthetics during live streams. Chat messages appear cleaner and integrate more naturally with your video.
Faster & More Reliable Streaming
Core streaming performance has been improved for faster connections and more stable broadcasts across all supported platforms.
