Is there a kiosk mode for Android and does Skie have one?
Yes. Android has kiosk-style locking for device-owner apps, and Skie offers full-screen kiosk mode on managed phones and tablets. The device shows one experience, the user cannot leave it, and the admin controls it from the dashboard. A one-app allow list also locks a device to a single app.
Kiosk mode means the device is locked to a purpose. Instead of a home screen with many icons, it shows a full-screen app or a tight set of apps and nothing else. People use it for shop demo tablets, order-taking tablets, customer-facing screens and exam tablets.
On Android this is only possible reliably when the management app is the device owner, which is how Skie runs. The rules are enforced by Android itself, not by an app the user can close. A device must be freshly set up or reset once to become managed, with any Google account removed first.
Skie gives you two ways to get there. Full-screen kiosk mode locks the interface itself. A one-app allow list makes the app list contain a single app. Both can be combined with policy switches such as camera off, Bluetooth off, screenshots off and the Play Store hidden, plus the always-on hardening that blocks factory reset and safe mode.
The admin keeps control. Changing the group's policy or app list changes the kiosk, and the change reaches the device on its next sync. A practical tip: always test kiosk on one spare tablet first, and write down the steps to change or disable it before you give any device to a customer. See the Android device owner explainer for why this needs device-owner status.
