It’s not watch specific but tied to your phone. It pulls all the data from your CGM and offers more insight than the native app offers.

You can record your meals by taking photos, leaving descriptions, or scanning UPCs. It already has the info for popular franchise meals.

The best part is if your levels are dropping too much and too fast overnight, it will call your phone and make your watch sound and vibrate. It’s waken me enough times that I should send some thank you money to the developer

Did I mention it’s free?
