About Diapo
Diapo shows your photos big on screen, folder by folder. You go from one to the next with a swipe, and your photos are never modified.
VIEW
• Every photo on the phone, sorted by folder.
• Swipe to go from one photo to the next, pinch to zoom, double tap for full screen.
• Three modes: Full Screen, Filmstrip (the photo and a strip of thumbnails) and Contact Sheet (a grid of thumbnails).
• Photos are shown the right way up, from their EXIF orientation.
• Diapo resumes at the last photo seen in each folder.
FORMATS
• JPEG, HEIC, PNG, WebP, GIF, BMP and RAW (Canon CR2/CR3, Nikon NEF, Sony ARW, DNG…).
FAVORITES AND SELECTIONS
• A heart adds a photo to your Favorites.
• Selections: mark photos with a tap, then copy them into a folder to share them. Duplicates are skipped by their content.
YOUR PHOTOS STAY UNTOUCHED
• Diapo never modifies, moves, renames or deletes a photo. It only makes copies, when you ask for them.
• No ads, no tracking, no account.
PRICE
• 14-day free trial, then a one-time purchase to keep using it. No subscription.
Available in 28 languages.
