iZoomViewer, an innovative & revolutionary way to explore & discover digital media. You magnify one image to reveal thousands more, endlessly. Content Interface's iZoom (Infinite Zoom) is an infinitely zoomable mosaic of photos and videos. iZoomViewer allows the user to select an iZoom from a list of many iZooms to zoom in. While zooming, each pixel is gradually morphed into another image or video which is morphed further into others, endlessly. Each iZoom contains thousands of images and photos, providing you with hours of entertainment and education. How to set custom cover image for an iZoom scene: 1) Tap the gear button to open the Setting menu. 2) Tap "Cover" to open the child menu. Then tap "Camera" to open the camera screen, or "Gallery" to selecting a photo from the device's Photo app. 3a) In the camera screen, tap anywhere to capture the photo. 3b) Tap the V tick button to set this captured photo be the cover image of the current scene. 4a) After select a photo from the device's Photo app, a photo preview screen will be opened. 4b) In the photo preview screen, tap the V tick button to set this selected photo be the cover image of the current scene. Functions of other buttons in the camera screen: - ">>" : Switch to the next camera of the current type (iPhone Pro models may have 3 back cameras). It is hidden if the current camera type has only one camera. - AF : Auto focus mode. Tap it to switch to MF mode. If it is still AF, then the current camera does not support MF mode. - MF : Manual focus mode. Tap it to switch to AF mode. Notes about the camera screen: - In captured state, these buttons will be hidden : AF/MF, ">>". - In live state, the V tick button will be hidden. - In MF mode, the tap gesture is used for setting camera focus point. So a circle button will appear for setting captured and live state of the camera.

ReceptionRating · Positive reviews · Number of ratings

iZoomViewer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ProCamera. Professional Camera has 11K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of ProCamera. Professional Camera's written reviews are positive against 50% of iZoomViewer's, so the app with the better star average is not the one people write more warmly about.
