BlurOne - Face Blur & Mosaic

Someone else's face ended up in your video, but editing apps feel too complicated, and upload-based blur apps make you uneasy about where your footage goes?

BlurOne blurs faces and mosaics sensitive details entirely on your device — nothing is ever uploaded to a server. When a passerby or friend shows up in your Reels or Shorts, BlurOne finds every face automatically; just pick who to blur and tap once.

Key features

▶ Fully on-device privacy
Face detection, tracking, blurring, and export all happen only on your device. No video, photo, or face data is ever sent anywhere. It even works in airplane mode.

▶ Free and unlimited, full-resolution exports
Automatic face blur is free and unlimited. You'll see ads while BlurOne is working, plus one short rewarded ad before export. Free exports keep the full original resolution — exactly as previewed.

▶ One-tap face blur + object tracking
Load a video and BlurOne automatically finds every face and shows them as thumbnails. Pick who to blur, and the app builds a track that follows them through the entire clip. You can also draw a box around anything else — a screen, a logo, or any other area — and it will be tracked and covered automatically. Play back the preview at any time to confirm everything stays covered.

▶ Four cover styles with fine control
Choose from blur (Gaussian), mosaic, solid color, or an emoji sticker, and fine-tune intensity and edge softness. Emoji stickers sit right on top of a face, so a clip keeps its mood while the person stays anonymous. What you see in preview is exactly what you get in the exported video.

▶ Trim to the part you need
Drag the handles at each end of the timeline to set where the export starts and ends — only that section is saved. Useful for pulling one scene out of a long clip, or cutting dead air off the beginning and end.

▶ Plans
- Free: every feature — automatic face blur, object tracking, and full-resolution export — available with ads (shown while working, plus one short rewarded ad before export).
- Lifetime unlock (one-time purchase, not a subscription): removes ads only. No feature differences.

Precise silhouette blur that follows a person's exact outline is planned for a future update; processing time may vary depending on device performance.
