Due to the weak vibration I tend to not feel the vibration on my Moto360 from time to time. I've been searching for an app that would allow me to change the vibe pattern for months to no avail. My problem was solved by an app I already had installed on my phone. Yesterday Light Flow just updated their app to allow vibration patterns and repeating vibrations to notify your wearable device. I just tested this out and it works great!! I have mine set to 3 long vibes. I hope this app helps the people who complain about the weak stock vibration on their Moto 360. BTW I have no vested interest in Light Flow.
