Caturday

Every default photo comes from a public post on mastodon.social, collected from the hashtags #cat, #caturday and #catsofmastodon. Photos are checked on-device to confirm they show a cat, and near-duplicates are filtered out before they become part of the curated set. The app and widget always offer a direct link to the original post. Caturday Pro can instead display still images from one Photo Library album you choose; those images stay on your device.

No. Caturday creates no account and asks for no email address or password. It only needs your device to be signed in to iCloud to sync the shared cat-photo cache. Caturday contains no analytics, no tracking and no advertising.

Caturday is rated 4+ on the App Store.

A current cat is shown and changes on a schedule, so there is a new one waiting whenever you open the app. You can also browse the collection and choose another cat at any time. Photos are stored on your device, so an already synced cat is there even without a connection.

1. Long-press an empty area of your Home Screen until the icons jiggle.
2. Tap the + button in the top corner.
3. Search for Caturday and choose a widget size.
4. Tap Add Widget, then tap Done.

Open a cat and drag the photo with your finger: on devices that support it, the picture is separated into foreground and background, and the layers shift against each other as you drag, so a flat photo gains real depth. All of it is computed on your device — no photo is sent anywhere for it.
