Smartwatch users, want something shiny and new to track all your health levels ? Samsung’s latest Oura Ring-rivaling piece of tech , the Samsung Galaxy Ring , officially launches on July 24 , but if you preorder it now for $400, you’ll get a free sizing kit, valued at $10, as a bonus gift. That freebie isn’t frivolous, either. Based on recent reviews about the ring , its comfortable, barely-there fit is one of its best features so getting a gauge for your Samsung ring size before you have it on can help ensure it isn’t too big or too tight.

Samsung’s smart ring comes in three allegedly scratch-free and water-resistant finishes, Titanium Silver , Titanium Gold and Titanium Black , all of which retail for $400. You can choose from nine size options, too, ranging from size 5-13. You can only use the Galaxy Ring with an Android device, unlike the Oura Ring which is compatible with Androids and iPhones.

According to the brand, you’ll also get the “best” Galaxy Ring experience when you’re pairing it with a Galaxy phone or smartwatch. The ring features Galaxy AI-enhanced health insights with three sensors that monitor vital metrics, such as sleep quality, heart rate, blood oxygen levels, skin temperature and workout performance workouts. You get all these personalized insights saved directly to your phone on the Samsung Health app, which displays your insights on a dashboard at a glance, from sleep patterns to fitness progress.
