Store description excerpt
Straighten presentation slides—even from an angled seat. Rectify is a camera app for lectures, conferences, meetings and presentations. It detects the projected slide, corrects perspective and saves a clear front-facing image. AUTO CAPTURE Start Auto Capture and keep the camera pointed at the screen. When the slide content changes and becomes stable, Rectify can capture it automatically. You can also use the shutter button at any time. PREVIEW BEFORE CAPTURING See the detected corners and a live corrected preview before you save the image. Turn correction on or off directly from the camera screen. CHOOSE WHERE EACH VERSION GOES Set a separate destination for the original and corrected image: • In the app • Photo Library • Both • Don’t save By default, the original stays in the app and the corrected image is saved to Photos. BROWSE BY DATE Review, share, export or delete in-app images from a simple date-based gallery. Deleting an in-app copy does not delete the copy in Photos. ON-DEVICE IMAGE PROCESSING Slide detection and perspective correction run on your iPhone. Captured images are not uploaded for image processing, and the app does not record audio. Great for: • Conferences and talks • Classes and training • Meetings and presentations • Projected documents, whiteboards and large displays Please follow the photography rules of the venue and respect the rights of the presenter. Detection and auto capture may vary with distance, lighting, motion and slide content.
