Professional capture. Cinematic color. CDNC is an iPhone video camera with manual capture controls, built-in Film Looks, and precise color grading tools. Set exposure, shutter, focus, and white balance before you roll, then shape the finished image in the same app. START WITH GOLD 200 Gold 200 is included free: monitor with it while filming, refine your clips, save finished edited versions, and export. Core recording, supported capture formats, manual controls, import, playback, basic editing, original-file export, framing guides, and the histogram are also included. CHOOSE A FILM LOOK Try other built-in Film Looks live in Camera or in the Editor before upgrading. Camera labels a Pro preview and asks you to unlock or switch to free Gold 200 before recording. CDNC Pro unlocks recording while monitoring these Looks, saving finished edited versions, and export, plus reusable creative presets and advanced monitoring tools. REFINE THE COLOR Shape your image with exposure, contrast, highlights, shadows, temperature, tint, saturation, skin tone, primary color wheels, curves, and seven-band HSL controls. Make color adjustments before the Film Look, then refine texture with diffusion, grain, lens blur, and sharpening. Dedicated Frames, Resize, and Trim tools help finish the composition. Preview Effects while editing. CDNC Pro is required to save or export with active Effects. To finish for free, choose Gold 200 without Effects and keep your color and composition adjustments. RECORD IN PRORES 422 HQ Capture ProRes 422 HQ original recordings in supported Apple Log and Apple Log 2 modes on compatible iPhones. HQ preserves a 10-bit 4:2:2 original for further grading. It requires substantially more storage than HEVC. Finished graded video exports use HEVC. SHUTTER DRAG. MADE IN CAMERA. Create native 1/5-second motion blur on supported camera configurations. Record and play back normally, then refine your Film Look and color in the Editor. The exposure blur is part of the recording; your grade stays editable. STEADIER SHOTS. SIMPLER FINISHING. Use CDNC Steady (Beta) to analyze a clip, choose Smooth Motion or Fixed Tripod, and adjust the amount. An optional camera Level helps line up your shot. Select your whole Media library and copy or move originals with saved CDNC edits to a Files location or external drive. ONE PRO TIER. YOUR CHOICE. Choose a monthly subscription, annual subscription, or one-time lifetime unlock. Each provides the same Pro access. Lifetime includes future core app improvements and additions to the standard CDNC Film Look collection; separate future products, services, or licensed collaboration packs are outside that promise. Monthly and annual subscriptions renew automatically unless canceled. See the in-app purchase screen for current local prices and terms. Manage subscriptions through your Apple Account. A lifetime purchase does not automatically cancel an existing subscription. Capture formats and monitoring options depend on your iPhone and system support. CDNC focuses on capture and look/color refinement, not a multitrack editing timeline.

Verdict
The clearest difference is update cadence: CDNC at every 4 days against Duo Video's every 3 weeks. Duo Video's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
