Dual Camera Video: TwinLens

TwinLens records two videos at once using your iPhone’s dual cameras — a 9:16 vertical for TikTok, Reels, and Shorts, and a 16:9 horizontal for YouTube — from the same moment, at the same time.

Your portrait file comes with auto-captions burned in, ready to post.

Film once. Post everywhere.

No more re-shooting when the moment’s gone.
No more cropping vertical clips for YouTube and watching the quality turn to mush.
No more round-tripping through CapCut to add captions and export twice.

Press record. Get both. Captioned.

WHAT YOU GET

• Simultaneous dual-aspect recording — 9:16 portrait + 16:9 landscape from one take
• Auto-captions burned into the 9:16 file — on-device speech recognition (no cloud, no account)
• Built-in teleprompter — paste a script, auto-scroll while recording
• Optional creator watermark — your @handle in the lower-right
• Scene tags — Vlog, Podcast, Tutorial, Event presets (or custom naming)
• In-record trim — cut the start/end without leaving the app
• Native quality on both files — true 16:9, not cropped
• Automatic save to a dedicated “TwinLens” album
• Tap to delete within 5 seconds if the take was bad
