Okay, head Is spinning today. Got this handy unit for Christmas, but I'm not sure which app to use with it to suit my needs, or if this unit will even do that. I'm needing something to monitor me through the day steps, etc., that can loop with my fitnesspal. I need the HRM for during exercise for targeted heart rate. Am I going to have to purchase an app to get this to work like I want it to, or should I return it and get something else?? Any suggestions would be appreciated, I'm new to this technology thanks!
