I have provided for you a link that lists all of the specifications about this device. https://www.samsung.com/us/mobile/wearables/smartwatches/galaxy-watch--42mm--midnight-black--lte--sm-r815uzkaxar/#specs. The Galaxy Watch does comes with Samsung Health. When it comes to other apps, it all depends on the compatibility. Thanks for reaching out to us. ^Monique
