DigSig

Photo & Video Slideshow for iPad

Turn any iPad into a dedicated photo and video slideshow display — for a digital photo frame, a reception desk, a shop window, or anywhere you want your own media on a loop.

DigSig plays entirely from photos and videos you import yourself. There’s no cloud account, no ads, and nothing ever leaves your device.

Version 1.0 · Designed for iPad · Requires iPadOS 16.0 or later · Age rating 4+

What it does

Your media, your folders

Import photos (JPEG, PNG, HEIC, TIFF, GIF) and videos (MP4, MOV, M4V) straight from Files. Organise them into folders and build as many playlists as you need.

Transitions that suit the room

Four styles: a slow Ken Burns pan and zoom, crossfade, hard cut, or fade to black. Fill, fit or stretch to match your screen.

Brand it with an overlay

Drop in your own transparent PNG frame or logo and attach it to any playlist — useful for shop windows and reception screens.

Schedule by clock or by sun

Trigger playlists at set times, or relative to local sunrise and sunset, on the days of the week you choose.

Dims itself when it should

Auto-dim at night, or automatically when nobody is nearby — detected on-device, with nothing recorded.

Hands-off playback

Fullscreen, no chrome, no distractions. Start a playlist by voice with Siri Shortcuts; hold the screen for three seconds to exit.

Privacy by design

DigSig doesn’t collect, transmit, or share any data. Your media, playlists and settings stay on your iPad. Camera and location access are both optional, used only for on-device presence detection and sunrise/sunset calculation — nothing is ever recorded or sent anywhere.
