I would like to know which fitness tracker or sport watch has a good heart rate monitor built in that provides notification from incoming call and messages from my phone. I'm thinking of getting the Garmin Forerunner 230 but it doesn't record HR 24/7. As for 235, i read that the HRM is not that good. I need one with good HRM because i have a heart problem. I want a sportwatch for running so I can get ready before the basic training for army. Budget is 300. I can go higher if i need to.
