Zero Duplicates

I’m working on Zero Duplicates, a duplicate file finder for Mac, iPhone, and iPad.

The app detects duplicates by comparing actual file content rather than filenames or metadata. It shows exact matches and lets you decide which versions to keep, ensuring at least one copy always remains. My focus has been on keeping it lightweight, predictable, and safe, especially for large photo libraries.

You can download Zero Duplicates for free on Mac, iPhone, and iPad and run unlimited scans at no cost. Deletions up to 1 GB are free. For anyone who wants to try the full version, the first month is free, redeemable until January 31 using promo code JAN2026.

I’m actively developing the app and would really appreciate feedback. If you have questions, feature ideas, or think something is missing, please leave a comment. I read everything and use it to guide development.

If the app ends up being useful to you, an App Store review also helps a lot with keeping the project going.
