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 CREATOR-FIRST CONTROLS • Spring-morph record button with haptic feedback • One-handed zoom — presets (1x, 2x, 5x) + drag dial • Tap to focus, long-press to lock AE/AF • Flashlight, stabilization, grid toggles • Pause and resume mid-recording • Volume buttons trigger recording • Settings remember your last configuration QUALITY OPTIONS • Resolution: 4K or 1080p • Frame rate: 24, 30, or 60 fps • Quality: Low, Medium, High (variable bitrate) • Format: MOV (HEVC, editor-friendly) or MP4 (H.264, share-friendly) WHO IT’S FOR • TikTok, Reels, and Shorts creators who also post to YouTube • Podcasters capturing B-roll • Vloggers and journalists • Anyone tired of cropping, reformatting, or using multiple apps PRIVACY TwinLens runs entirely on-device.
