## Version history (last 5 releases)

### 1.7.3 — 2026-10-24

New: Scrambler
Scramble any photo or video like a signal from something not of this world. Tear it, roll it, cut it into blocks, split the colours and bury it in static. Let it pulse in and out, hit on a tap, or follow the sound in the room, so it scrambles to a beat or a voice. Videos keep their sound, scrambled right along with the picture. Send it full screen to a TV over HDMI or AirPlay and run it live from your phone.

Operator
• Launch on the lock screen or the home screen, and line up calls, video calls, texts, emails and notifications in one Actions list.
• Video calls with your live camera or a clip, contact posters, and quick text replies on incoming calls.
• Open Strike Up, Live Feed, News, CineVault and Custom Stitch from the home screen, then swipe up and the app shrinks back into its icon, like a real iPhone.
• Lock screen clock that runs live, with an editable date.
• Guided Access status and a quick how-to in Setup, to keep takes locked on screen.

News
• Stories can hold a video that plays on its own once it's on screen.

Messenger
