What kinds of wearables are you guys using that aggregate data to the health app? I'm looking for something with heart rate, and distance trackers (gps would be a plus, but not required), waterproof/resistant, and sleep tracking. It would be nice if it could go at least a few days before a recharge. I know there's stuff from Fitbit, jawbone, basic, Microsoft, etc. I've been looking around at reviews and stuff, but wanted to see if anyone had any firsthand experience with them and/or recommendations or ones to stay away from. I'm looking to keep it under or right at $200, hence the reason I'm not waiting for the apple watch.
