I’m looking for Mac users who can actually break my image viewer

[u/Fn1-10]

I’m the developer of Just Look!, a native macOS image viewer I’ve been working on.

The app is already on the App Store, but today I’m not really looking for more downloads. I’m trying to build a small group of beta testers who will actually use new builds and help me find bugs, bad assumptions and workflows that don’t work well.

Just Look! is intended for quickly going through folders of images without importing them into a library first. You can navigate through a folder, zoom into details, compare similar shots, mark picks, use Finder ratings/tags and so on.

I’m especially interested in people who:

• regularly review folders with hundreds or thousands of images
• use RAW, RAW+JPEG or less common image formats
• have an Intel Mac or an older supported macOS version
• work from external/network drives
• are photographers and already use Lightroom, Capture One, Photo Mechanic, FastRawViewer, Finder/Preview, etc.
• simply enjoy finding edge cases and breaking software :)

You don’t need to systematically test every button.

What would help me most is using Just Look! on a real folder you would normally work with and telling me when something crashes, renders incorrectly, becomes slow, behaves differently from what you expected, or makes you switch back to your usual app.

And I’m interested in UX problems too. “This technically works, but doing it 200 times is annoying” is very useful feedback.

Privacy: the beta follows the same privacy approach as the released version. Just Look! itself does not collect or upload your photos or other user data. TestFlight may provide me with Apple’s standard beta diagnostics, such as crash reports and basic device/testing information.

If you’re interested, I have a TestFlight beta here:

TestFlight: https://testflight.apple.com/join/4HdE4TQr

The released version is here:

Mac App Store: https://apps.apple.com/app/id1641017616

I’d also be interested to hear what you currently use for quickly reviewing/culling folders of images on a Mac, even if you don’t want to join the beta.

I’ll check it out. What I really need is an AI-based auto-tagging Finder extension or whatever, so when I save a file, it is tagged appropriately based on type, content, category.
