App Idea: Sanctus Bells

I went to a wedding this weekend, and the silence of no sanctus bells during the consecration was noticeable. Why not an app for that? There’s nothing in Google Play nor the Apple Store. Sanctus bells aren’t cheap, and they pack a loud punch. The enterprising altar boy can easily connect to the church’s PA system via Bluetooth and operate his phone’s shake event detection discretely inside his surplice sleeves.
