Not what I thought
I thought it would be a wallpaper to get into my phone not a shortcut app
Response from developer
"Hi! Thank you for your review. Due to Apple's strict system restrictions, no third-party app is allowed to replace the native iPhone lock screen. Using the Shortcuts app is currently the best possible way to bring the Zipper lock experience to iOS! For a much smoother and faster experience, we highly recommend adding our App Widget directly to your Lock Screen Or home screen. Also, the app is much more than just a zipper interface—it includes a built-in Secret Vault where you can safely hide your private photos and videos behind the zipper. We hope you give the vault and the widget a try!"
