Whoo - Fun Face Swap Tool

Snap a face. Swap a world.

Picture this: you've just captured the most magical moment at a family gathering. Laughter frozen in time, genuine joy radiating from every face in the frame. It's perfect—except you're not quite ready to share everyone's faces with the world. Perhaps it's a friend who values their privacy, a child whose digital footprint you'd rather protect, or simply your own face on a day when you'd rather remain anonymous.

You reach for the trusty mosaic blur. Drag, resize, position, repeat. By the third face, you're questioning your life choices. By the fifth, you've abandoned the photo altogether.

That's precisely why we created Whoo.

One Tap. Instant Privacy.

Whoo is the fastest way to mask faces in your photos. With just one tap, automatically detect all faces and replace them with cute Emojis, artistic Rock paintings, or festive Eggs. It turns privacy protection into a creative feature.

Perfect For:

• Sharing Kids' Photos: Keep those core memories while shielding your child's identity with adorable stickers. • Group Photos: Respect everyone’s privacy in group shots without hiding the fun. • Meme Creation: Swap friends' faces with funny expressions for inside jokes. • Social Media: Maintain a bit of mystery while staying active online.

Features

Instant Detection

Advanced on-device technology detects every face in your photo instantly. No manual selection needed.

Live Photos & Videos

Whoo doesn't stop at still photos. Live Photos come back to life with stickers riding every frame — sound, timing, and all preserved. Videos get the same treatment: pick any clip up to 60 seconds, and Whoo works through it frame by frame, saving the result straight to your library.

Creative Sticker Library

• Emoji: The universal language of fun. Completely free forever! • Rock Art: Hand-crafted stone faces for a unique, artistic look. • Dyed Eggs: Colourful and festive options for any celebration. • Rambutan: Playful illustrated faces bursting with personality. • Lunar Horse: Elegant illustrated faces inspired by the lunar new year. • Custom Emoji: Add anything from the iOS keyboard — Emoji, Memoji, Genmoji, Live Stickers, and third-party packs. Add in batches, remove what you don't need. Syncs via iCloud.

Your Stickers, Your Order

Long-press any sticker to rearrange the gallery. The order matters — when Whoo detects faces, it assigns stickers from left to right. Drag your favourites to the front so they're always picked first. New emoji you add land at the very front automatically. Your arrangement syncs via iCloud.

Mix & Match

Give each person in the photo their own sticker theme. Tap a face, swipe to a different category, and only that face changes. Every combination is fair game.
