The whole edit,
on your phone.
Record on your iPhone, finish on your iPhone. BRoll King cuts the silences and the blown takes, plans B-roll around your transcript, styles your captions and renders the final video on the device — no desktop editor in the loop.

One email at launch. Nothing else.
What the app does
The same four steps as the web app, built for a phone screen and a thumb.
Pick a video
Choose a recording from your library. The audio is analysed on device first, so the scan starts immediately and your video file never leaves the phone.
Review the cuts
Silences, filler words and restarted takes arrive as a list you can scroll, uncheck and fine-tune. Nothing is removed before you say so.
Review the B-roll plan
Each suggested insert shows its moment, its source and why it was picked. Swap it, regenerate it, or drop it.
Caption, render, save
Captions are styled to taste and burned in, the video renders on device, and you save it to Photos or share it straight out.
Built for the phone
On-device silence scan
Loudness analysis runs locally on your iPhone. No upload, no waiting on a server to tell you where the dead air is.
Renders on device
Cuts, B-roll overlays, slow zooms and captions are composited on the phone and exported at 1080p, ready to post.
Editable caption styling
Font, size, characters per line, position, casing, shadow, and a background box with its own colour, opacity, padding and radius. Correct a misheard word before it burns in.
Sign in with Apple
Sign in with Apple or Google. Your credit balance lives on the account, so it follows you to a new phone.
Free to start
