Help me shop for a new activity tracker?

I so want to joint the activity tracker craze, but the fitbit just doesn't have what I want. I looked around a bit. Got very excited about the OMbra (http://mashable.com/2016/01/07/ombra-sports-bra-fitness-tracker/#iW17RuCQx8qN), but waited a year for it and don't think it will ever be released. If anyone has any suggestions, let me know!

I am looking for an activity tracker with the following features, listed from most to least important. The only REQUIRED features are bolded. The rest would be great added bonuses.
1. Real-time active heart rate tracking
-Tracks heart rate from start of finish of a work out
-See a read out of current heart-rate on the spot
-Tracks time spent in various heart-rate zones
-Tracks averages
-Prefer chest sensor. If not a chest strap, a high measure of accuracy can be predicted
2. Battery lasts 24 hours minimum
3. Not a watch. If it must be a watch, the face is small. I have a watch I love and don’t feel like wearing 2 watches.
4. Works with variety of apps (not limited to sync to one app to some company that might go out of business any moment)
5. Non-aerobic heart rate tracking
-Checks resting heart rate
-Checks heart rate throughout the day
6. Wi-Fi, NFC or Bluetooth syncing. If must sync corded, then simple interface
Accelerometer and/or GPS to track distance or steps specifically up and down stairs.
7. Monitor for breathing/respiration
