Heii! We're happy to announce that the Heii On-Call app for iOS has been granted the Critical Alerts entitlement by Apple. This means that alerts from Heii On-Call will always play a sound and deliver a notification, even if your phone is silenced or has Do Not Disturb enabled, making sure you never miss a single alert from any website monitoring you have configured. This also helps make sure you are able to respond when it is your turn in an on-call rotation, preventing the incident from being escalated to another member of your team.
Update to the latest version of Heii On-Call for iOS and you will be asked to grant the app permission to deliver Critical Alerts.

- Set your phone to silent.
- Enable Do Not Disturb.

- Tap the power button to put your phone to sleep.
- Using your computer, from the Notification Channels configuration page, send yourself a test message.
