I've bought a smart bracelet (ID115 by LETSCOM) for its silent alarms as advertised:
Wake you up peacefully with a silent alarm.
Alarm Alert: Set silent alarms on the tracker to wake you up without disturbing your family.
However, when setup Alarm Alert as Get Up in VeryFitPro app (for iOS) and synced via Bluetooth, but the bracelet keeps beeping till I start shaking my hand or by pressing the button, therefore it's disturbing others. What I'm looking for is to set up the alarm using silent vibration only (without beeping).
I've checked the app and manual, but it's not clear for me how to do it.
