Download & Install
Winder runs on iOS, macOS and Android — one app, the same darkroom everywhere. Grab it from the App Store or Google Play.
What you need
- Scans from your lab. Standard 35mm scans in JPEG or PNG. Each file holds two of your half-frame shots side by side — that's normal, and it's exactly what Winder expects.
- Nothing else. No account, no sign-up, no cloud. Winder works the moment it opens.
Platform differences
| iOS | macOS | Android | |
|---|---|---|---|
| Splitting & library | Yes | Yes | Yes |
| Library in a folder you choose | Yes | Yes | App storage only |
| Home-screen widgets | Yes | — | Yes |
| Alternate app icons | Yes | — | — |
On Android the system hands apps a content:// tree rather than a real
directory, which Winder cannot open as a folder, so the library stays in app
storage and the folder picker is hidden rather than shown broken.
