bt notifier to conect smartwatch android to iphone 6

Hi, good day to all,

I have a trouble to enable the notifications from my iphone 6 on a smartwatch android, the watch display a message that says "Please install BT Notifier app in remote", but when I search on App Store, and does not exists, that app does not appear.... then I don't know if exists other way to enable the notifications on the watch...

Version of the watch is M26_OPT.FN4.V013_V7

Device connect by bluetooth to iphone correctly, and I can see my phonebook and make calls, listen music too... but it does not receive any notification....

Someone can help me please? thanks...
