Winnow: Regroup camera bursts inside the macOS Photos app

Hey Product Hunt — I’m Dominik, maker of Winnow.

I got a mirrorless camera and kept dumping bursts into Photos on my Mac. Photos is fine for iPhone bursts; for everything else it’s just dozens of near-identical stills with no “pick the sharp one” workflow. Full catalogs solve it if you leave Photos. I wanted to stay in the library I already have.

Winnow:

• Rebuilds camera bursts by capture time

• Filmstrip + actual-size zoom that sticks as you step frames

• Side-by-side pin/compare with shared zoom & pan (1.2)

• Sharpest / Softer badges from the image itself (hints only — never auto-deletes)

• Deletes go to Recently Deleted; macOS confirms

• Offline: no account, no analytics, no network

$9.99 one-time on the Mac App Store. macOS 14+.

AMA. Especially useful feedback:

1) Does burst grouping match how you shoot (birds, sports, kids)?

2) Are Sharpest/Softer helpful or in the way?

3) What would make you trust a Photos helper with your library?

Happy to answer anything.
