CatchSlide: Lecture Slide Scan

Slides photographed from the back row always come out crooked, and they get lost between selfies and receipts. CatchSlide is a camera just for presentation slides: it captures them, straightens them, and keeps them together.

Straight, every time
The camera finds the four corners of the slide as you aim. Shoot from any seat and CatchSlide flattens the slide as if you were facing it head on, cropping away the room. A green frame tells you it is locked, and auto capture can take the shot for you.

Silent
There is no shutter sound, so you can capture slides in the middle of a lecture or talk without disturbing anyone. Blurry shots are skipped automatically.

Organised by session
Slides you capture in a row are grouped into one presentation. Give each one a title, reorder slides, or merge presentations together.

Straight from Photos
Already have lecture photos? Select several in Photos and share them to CatchSlide. They are straightened, sorted by the time you took them, and filed as one presentation.

Search the words on your slides
CatchSlide recognises the text on every slide, so a single word you remember brings back the slide from a lecture weeks ago.

Sharper text, then PDF
Enhance Readability clears shadows and faded contrast. Export a presentation as a study PDF with one, two, or four slides per page, or share the images.

Capture from the Home Screen
Tap the widget and the camera opens right away. It works on the Lock Screen too.

Your slides stay on your device. No account or sign-in needed.
