About this app

React, film and edit — one vertical video, ready to post anywhere.

Duovid plays a video while you record your reaction next to it. Or film just yourself, or edit the clips
you already have. Add captions, text and music, then export without a watermark. Free, no account needed.

THREE WAYS TO START
• React to a video – a video plays while you record your reaction next to it. Pause, resume and retake
whenever you want; the sound stays in sync.
• Selfie video – just you and the camera: full screen, rounded, circle or green screen.
• Edit a video – no camera needed. Add text, captions and music to videos and photos you already have.
Mix it up later: selfie, duo, photo and video clips can go into the same project in any order.

6 REACTION LAYOUTS
Top / Bottom, Side by Side, Bubble, Circle, Reverse Bubble and Green Screen. Switch layouts while
recording or afterwards, drag and resize the bubble, and mirror your selfie.

BUILT-IN TELEPROMPTER
The prompter sits right under the front camera, so you keep eye contact while you read.
• Write or paste scripts and keep a library of them
• Adjust speed, text size and colours, with a reading line and mirror mode
• Move, resize or hide the window
• Countdown before the text starts scrolling

EVERY CLIP, ONE TIMELINE
• Line up selfie, reaction, photo and video clips and rearrange them
• Trim clips, change the layout after recording and undo anything
• What you see in the preview is exactly what you export
• Drafts are saved automatically

AUTO CAPTIONS IN 100 LANGUAGES
Duovid listens to your voice and writes the captions for you, right on your iPhone. Your voice is never
uploaded, and once a language is ready it works without internet. Fix any word or timing line by line,
then pick a style. Includes a dedicated Albanian speech model for accurate captions in Shqip.

TITLES THAT POP
• Add titles, captions and credits
• Drag, pinch and rotate text right on the video, and choose when each one appears
• Rounded, Classic, Serif, Mono and Condensed fonts
• Plain, outline, box or neon styles, in any colour and size
• Stack, duplicate and layer as many texts as you like

MUSIC, SOUNDS AND VOICE-OVER
• Add background music from your Files
• Use the soundtrack of another video
• Record a voice-over while the video plays back
• Set the volume of every track separately, balance the original video against your voice and fine-tune
their sync

EXPORT AND SHARE
Export in 720p, 1080p or 4K. Save to Photos or share straight to your favourite apps. You can also send a
video to Duovid from the share sheet of another app and start reacting right away.

PRIVATE BY DESIGN
Your videos stay on your phone. No account, no sign-up, no watermark.
