Does anyone have a suggestion for a simple heart rate app? I want an app that will do one thing only, tell me my current heart rate. I don’t want to be required to sign up for an account to store past readings or compare my stats to others. I just want to know my current heart rate no more. I’ve gotten frustrated with what I’ve found in the App Store as every one that I’ve looked at all have every imaginable bell and whistle none of which I need or want.
