Mosaic
Read full descriptionHide full description
Mosaic is a quick way to hide the parts of a photo or video you don't want to share. ■ Three ways to choose what to hide ・Lasso: trace around an area with your finger ・Rectangle: drag a box over it ・Faces: Mosaic finds every face for you and covers them all at once ■ Choose who stays visible When several people are in the shot, keep one face visible, or hide just one. Each face can be switched on and off. ■ Six styles ・Mosaic: the classic pixelated look ・Blur: soft and natural ・Pixel Blur: pixelated, with softened edges ・Scribble: hand-drawn lines that scribble it out ・Emoji: a different emoji for each face ・Black Bar: covers just the eyes Adjust the strength with a slider. It scales with the size of your photo, so small and large images both look right. ■ Video, too Open a video and Mosaic follows faces and the areas you drew, hiding them frame by frame. Check the tracking before you export, and redraw a box wherever it drifts. Audio is kept, and video is exported at full quality. ■ Precise control Pinch to zoom, drag with two fingers to move around, and double-tap to see the whole picture. Move any area with your finger, or delete just the one you selected. On Mac, zoom with the mouse wheel or ⌘+ / ⌘−. ■ Your photos stay on your device All processing happens on your iPhone, iPad or Mac. Mosaic never uploads your photos or videos. No account, no ads, no tracking. ■ Pricing Anyone can try every tool. A subscription is required to save to your Photos library. ・1-week free trial ・Then a monthly auto-renewing subscription (the price is shown in the app before you subscribe) ・Cancel anytime in Settings ▸ Apple Account ▸ Subscriptions ・Cancel at least 24 hours before the trial ends and you won't be charged ・The subscription renews automatically unless canceled Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://uuuu.to/mosaic-privacy-policy/ Works on iPhone, iPad and Macs with Apple silicon.

Cover what you don't want seen, then send the photo. ■ Drag to cover Drag over anything you want hidden and it's covered — mosaic or blur, your choice. Add as many areas as you need, each with its own settings. ■ Still editable afterwards Every area stays an object you can come back to, not a brush stroke that destroys pixels. Press and hold to move it, drag a corner to resize, change the strength any time. Each change is recomputed from the original, so nothing degrades. ■ You decide what gets hidden No auto-detection. Auto-detection misses things, and with redaction, missing one thing means the whole job failed. You choose what to cover and how hard. ■ Add text Put a note on top when you're done. Black, white and bold are free. ■ Full-resolution export The free version exports at original resolution. No watermark, no downgrade. ■ Works offline Photos are processed entirely on this phone and never uploaded. No account, no server. (Only three things reach the outside: in-app purchases, restores, and anonymous usage stats. The stats record which features you used — never your photos or the text you add — and you can turn them off in Settings.)

Verdict
The clearest difference is update cadence: Mosa at every 6 days against Mosaic's every 2 weeks. Mosa also leads on iOS requirement (17.0 vs 26.0). Mosaic's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
