Ratings and reviews

genuinely the most annoying editing app to deal with. the photos don't save properly 70% of the time, stickers don't lay over photos correctly, etc. just stick with pixart at this point.

photos move out of place when I save the file in gallery. it's frustrating and doesn't work properly. if it wasn't for this bug it would be a great app

The best app ever, I love using it for my posts and ig carrousels, pls pls never change I love this app and I love that it's free, and the background eraser is lovely the variety of stickers too!! 100% recommended

What’s new

Fixed what matters most — your work is safe now:
• Photos no longer disappear from projects after restarting the app
• Autosave: your drafts are waiting on the home screen
• Projects are kept even after exporting to the gallery
• "Open" and "Share" right after export
