Good basic features with BAD BUGS and room for improvement

BUGS:
1) Syncs all data multiple times to Apple Health:
- same steps up to 13 times (Mi Fit: 1.000 steps -> Apple Health: Up to 13.000 steps)!
- heart rate is synced several times to Apple Health.
- sleep is also synced several times to Apple Health.
==> GET IT FIXED immediately please!

FEATURE REQUESTS:
1) Re-Add early bird function
2) Continuous heart rate monitoring for exercises (start and finish via app)
3) Sleep: Detect "awake" time slots - currently a night walk to the bath is recorded as "light sleep"
4) Sleep: Ability to record daytime sleep
5) Allow export of all raw data (as csv via mail e. g.)
6) Steps: Allow edit of individual step length
7) Notifications: Add important basic apps like calendar
8) Add reminder function (for medicine or sleep time), currently only alarm-clock may be abused for this
