A few good photos. Several almost identical ones. Screenshots you no longer need. PicDecide helps you go through them one at a time. Swipe right to keep a photo, left to set it aside, or save it for later when you’re not sure. START WHERE YOU WANT Review all photos, screenshots, videos, an album, or a month and year. Start with the largest files, or sort your photos oldest first, newest first, or shuffled. TAKE A CLOSER LOOK Open a photo full screen and zoom in. Undo a decision, revisit your saved photos, or close the app and continue later. CHECK BEFORE YOU DELETE Swiping left only sets an item aside. Review your choices before requesting deletion. Apple Photos asks for confirmation before anything is removed. SEE YOUR PROGRESS Cleanup history shows your review activity and confirmed deletions. Review decisions and history stay on your device. MADE FOR YOUR IPHONE A simple black-and-white design follows your device’s light or dark appearance. No account, ads, or tracking. PicDecide does not upload your photos to its own servers. If iCloud Photos is enabled, deleting an item can also remove it from your other devices. Deleted items normally remain in Recently Deleted for 30 days. Original file sizes may differ from storage used on your iPhone; deleting photos may not free that space immediately. FREE TO USE Make up to 50 keep or set-aside decisions a day for free. Undo, Look Later, and removing what you set aside always stay free. PicDecide Lifetime is a one-time purchase that unlocks unlimited decisions. If you paid for PicDecide before it became free, unlimited decisions are already included.
