On-device.
Transcription, rendering, and export run on your iPhone. Your video never leaves the device.
Stylish captions for vertical video, written on your iPhone.
Open a clip. Sound Off transcribes the audio, animates the captions in the style you pick, and exports the finished video to Photos, Messages, or anywhere else you share to. Everything runs on the device.
One-time purchase
A small native iPhone app for captioning vertical video. The work runs on the device, and you pay for the app once.
Transcription, rendering, and export run on your iPhone. Your video never leaves the device.
Twelve caption styles, from word-by-word animation like Pop Yellow and Karaoke to full-sentence paragraph styles built for talking-head and podcast clips.
Sound Off is a single purchase, not a subscription. The app works on every iPhone signed into your Apple ID.
Free exports carry a small watermark. The one-time unlock removes it and opens the full caption style catalogue.
