RatioRoll: Dual-Format Camera

Vertical & Horizontal Recorder

Only for iPhone

Free · In‑App Purchases

iPhone

RatioRoll is now free, with an in-app Photos-backed Library for playing, sharing, and managing your dual-format clips. RatioRoll is the dual-format camera built for creators, shooters, and storytellers who need the same moment in both landscape and vertical formats. Record once. Walk away with both ratios. A single take captures a 16:9 horizontal master and a 9:16 vertical cut at the same time. No reshoots. No second setup. No forgotten vertical angle. KEY FEATURES • Dual-Aspect Recording — Capture 16:9 horizontal and 9:16 vertical simultaneously. Both files save to Photos, ready to edit or share. • In-App Library — Review the RatioRoll clips already saved in your iPhone Photo Library without leaving the app. The library uses Photos-backed assets instead of duplicating video storage inside RatioRoll. • Video Playback + Swipe Navigation — Tap any clip to play it, swipe across to the next clip, or swipe down to return to the grid. • Share + Multi-Select — Open the native iPhone share sheet for one clip or select multiple clips to share or delete with confirmation. • Open-Gate Framing — Use more of the sensor area so the horizontal and vertical frames both have room to work. • Pro Camera Controls — Exposure compensation, manual exposure controls, frame-rate options, tap-to-focus, and a clean recording HUD. • Apple Log + LUT Preview — Shoot Apple Log on supported iPhones with Rec.709 monitoring and live LUT previews. LUTs are preview-only, so your recorded files stay clean. • Monitoring Tools — False Colour and Zebra overlays help judge exposure while filming. • Front + Rear PiP — Add a front-camera picture-in-picture for talking-head and vlog framing. • 9:16 Safe Area Guides — Keep the vertical crop visible while shooting. FREE TO USE RatioRoll is now free. There is no recording paywall, no subscription gate, and no account required. PRIVACY • Camera and microphone access are used to record video and audio. • Photo Library access is used to save and display your RatioRoll clips. • No tracking. No third-party advertising SDKs. No cloud upload is required to record, save, or view clips. NOTES • iPhone-only. • Best on multicam-capable devices such as iPhone 13 Pro and newer. • Apple Log features require supported iPhone Pro hardware. Made by H3llo H3llo Ltd.
