TechCrunch laid out the main differences thoroughly in their review here https://techcrunch.com/2022/06/17/grace-debuts-privacy-focused-parental-controls-for-ios-devices-built-with-apples-screen-time-api/
Here are some highlights:
Much more intuitive interface
Flexible Schedules
Quick Actions Pause & Lock
Ability to customize restrictions for Downtime (block some apps, while allowing others)
You may also find this post useful: Grace vs Apple’s Screen Time
Grace and Apple’s Screen Time manage the device independently. Restrictions set in Grace can’t be disabled by Apple’s Screen Time and vice versa.
Grace and Apple Screen Time don’t sync and track restrictions statuses. For example, if you toggle “Block in-app purchases” in Grace, the same feature in Apple Screen Time stays disabled. Enabling Grace doesn’t automatically turn on Apple Screen Time and vice versa.
Technically, you can use Grace and Apple’s Screen Time together.
But here is the simple rule: the more restrictive rule wins.
So, for example, if you set up an App Time Limit for Youtube for 15 minutes in Grace and set up an App Time Limit for Youtube for 20 minutes in Apple’s Screen Time, then Youtube will be locked after 15 minutes of usage by Grace and will stay blocked unless something changes or a new day starts.
Our app works through Family Sharing. It works natively on iOS and lets you share Grace with up to five other family members.
First, make sure that Share Purchases with Family is turned ON in your Family Sharing settings.
When Grace+ screen appears on the child’s device, try tapping the “Restore Purchase” button.
If the step above doesn’t help, then try to download Grace to children’s devices according to this tutorial: Family Sharing guide. In other words, on the child’s device, try to download from the list of purchases shown in the Purchased section of your family member’s App Store account.
Currently, we support only one parent as an administrator (i.e. the one that authorizes parental controls with the Screen Time API on the child’s device).
It’s our priority and we will add multiple supervisors in one of the next updates soon.
The “Pause” quick action lets you temporarily turn off all restrictions you set for the child.
For example, let’s say you have Youtube as an “Always blocked” app, then the Youtube app becomes hidden on the child’s device. If you click Pause, this restriction temporarily turns off, letting Youtube appear on the child’s device, and Youtube can be accessed.
So the “Pause” action works if only there is a restriction already set up, and if you don’t have any restriction, then nothing can be paused.
Please check on the child’s device if notifications are enabled for Grace.
Go to Settings > Grace > Notifications > Tap Allow Notifications
Notifications should always be enabled on the child’s device.
