Hello, Syncing the KW88 with iPhone does not work properly.

Hello,
Syncing the KW88 with iPhone does not work properly. I can not get it to connect by bluetooth natively, and very badly with the Sinwear application. any solution? It is incredible that a smartwatch of 20 € is perfectly connected to my iPhone and the KW88 has so many problems.

Of course , but KW88 has problems with 3G coverage and battery duration. It is imposible to switch on wifi, 3G and Bluetooth all day. I need synchronize contacts, calendar and to receive notificarions of my iPhone.

It’s crap. No support on this, iPhone does not connect properly with this smartwatch. Once is connected the connection is instable, and disconnect frequently, without reconnecting again automatically. Every time it requests to pair, with this behaviour it’s a useless smartwatch. Another thing is about the whatsapp notifications does not display the sender name. With my work android phone everything is good, but the main one for me is the iPhone and so It’s very annoying.
