DuoO - Photo Slideshows
Photos in parallel
$2.99
Turn your albums into a continuous photo display. Set each panel's album and pace, with independent playback on supported iPad, Mac and Apple TV layouts.
DuoO turns album photos into a continuously playing parallel view.
Focus on one photo on iPhone. On iPad, Mac and Apple TV, choose one, two or three panels where supported. Each panel can advance, pause and select albums independently, while avoiding duplicate photos on screen.
• Global shuffle: choose photos randomly from eligible albums. Newly discovered eligible albums are included automatically.
• Immersive playback: multi-panel photos fill their panels while preserving proportions. Landscape photos in single-panel mode are shown in full by default. Photos fade between frames and advance after the next image is ready.
• Your own pace: adjust slideshow duration, pause a single panel or pause all panels.
• Album management: search, filter by count, sort and pin albums. Assign a different album to each panel.
• Skip viewed photos: mixed playback can skip photos already seen. Viewing history stays on your device.
• Device-appropriate controls: use touch, mouse and keyboard, or the Apple TV remote.
• Local-first playback: only downloaded photos are used by default. You can allow Apple Photos to retrieve iCloud photos on demand.
Album requirements: regular albums must contain 10–1000 images, with images making up at least 90% of their photos and videos. Some common download and recording albums are excluded. Multi-panel playback uses portrait and square images; single-panel mode also supports landscape images. Panel availability on Mac and iPad depends on window width. Apple TV content depends on the Photos library available to the system.
Choose Follow System, Simplified Chinese or English in Settings. Other system languages use English.
One purchase. No subscriptions, in-app purchases or ads. No account is required, and photos are not uploaded to the developer. Settings and viewing history are stored separately on each device.
