beurer HealthManager 4+

First of all, there's no iPhone 6/6s Plus interface optimization. UI seems stretched from smaller screen.
Second. No adjustment for the duration of vibration during wake up alarm (I use AS 80). Vibration continues for about 10 seconds and stops even if the device stays still. It means that if you didn't wake up during the vibration you will oversleep your wakeup time.
Third. There's no settings for adjustment of the indication for incoming calls and messages. AS 80 neither shows nor vibrating when I receive an incoming call. Bluetooth is always on.

I need a single feature from this app — get data from scales into the apple health app and it barely works, I can never know if I get measurements today or not and there is no way to force reading the data from the scales.

If I knew the app is this bad, I wouldn’t buy the Beurer scales in the first place. It’s unstable, it takes ages to proceed operations of syncing, and, what is worst, it “loses” connections between app account and scales user and wants to create on scales 8 users with the same data (or delete scales from app, there is no third option), I can’t even manage the scales users from the app, I can just add one (and deleting option would be more useful than adding - another user can sync from his own device). Anyway, right now I’m stressing every time I’m using this app, i can’t just get on the scales, weight and get the data in my phone.
